Porta Cabin Sizes & Dimensions Guide for UAE Projects

Porta cabin sizes and dimensions in the UAE range from 2m × 2m security booths to 3m × 12m (40ft × 10ft) large modular complexes. The two most widely used porta cabin dimensions across UAE projects are the 3m × 6m (20ft × 10ft) for site offices and the 3m × 12m (40ft × 10ft) for labor accommodation. Both are manufactured with 75mm polyurethane (PU) sandwich panel insulation and high-ambient air conditioning to withstand Gulf summer temperatures that regularly exceed 48°C.

Three compliance points worth remembering before you order anything:

1. Every habitable cabin needs a minimum of 75mm PU sandwich panel insulation.
2. Every habitable cabin needs a high-ambient, T3-rated split air conditioning unit.
3. Cabins on ADNOC, DEWA, Dubai Municipality, or Abu Dhabi Municipality-regulated sites must meet each authority’s own structural and occupancy rules.

A reliable porta cabin manufacturer in UAE will already build to these standards as default practice rather than as a paid upgrade, so it is worth confirming this with any supplier before you sign off on a size.

 

Why Porta Cabin Sizes & Dimensions Matter More in the UAE Than Anywhere Else

A procurement manager on a busy Dubai construction site places a porta cabin order. Three weeks later, a Dubai Municipality inspector arrives for a scheduled welfare check, measures the floor area, and flags the cabin as non-compliant.

Here is what usually happens next, step by step:

1. The site receives a 48-hour stop-work notice for that block.
2. The contractor scrambles to source a replacement cabin of the correct size.
3. Delivery takes several working days because the right porta cabin dimensions were not in stock.
4. The project timeline slips by almost a full week.
5. The contractor absorbs the rehousing cost, the penalty risk, and the reputational hit with the client.

This story repeats across construction sites in Dubai, labor camps in Abu Dhabi, and industrial installations throughout the UAE. The cause is almost always the same: the wrong porta cabin size was chosen, not because nobody cared, but because nobody had the right information before placing the order.

Most porta cabin guides online are written for a global audience, and they rarely mention that:

• A UAE summer renders a 50mm-panel cabin uninhabitable within months.
• MOHRE sets legally binding minimum floor area requirements per worker.
• Delivering a 3m × 12m cabin to a JAFZA project site requires a permit that some suppliers never mention upfront.
• A cabin’s advertised size and its actual usable size can differ by more than two square meters once insulation panels are factored in.

This guide closes that gap, and it covers:

1. Every standard porta cabin size available in the UAE, with internal and external dimensions.
2. How panel thickness reduces real usable space, and why this matters more in the UAE than almost anywhere else.
3. The exact regulatory thresholds set by MOHRE, Dubai Municipality, Abu Dhabi Municipality, and ADNOC.
4. Application-specific size recommendations for construction offices, labor camps, oil and gas sites, events, schools, and retail.
5. A five-step sizing decision framework built specifically for UAE project managers.
6. A short FAQ section answering the questions UAE buyers search for most often.

This guide is useful whether you:

• Manage a construction site in Dubai and need a compliant site office.
• Run a labor camp in Abu Dhabi’s industrial zones.
• Oversee facilities for an ADNOC contractor.
• Plan a retail pop-up in Sharjah or anywhere else in the UAE.

For projects that need a manufacturer rather than just information, Bait Al Maha has been building porta cabins, prefab houses, and modular site facilities from its Sharjah production base for use across Dubai, Abu Dhabi, and every other emirate.

 

What Is a Porta Cabin? Understanding the Basics Before You Compare Sizes

A porta cabin, also written as portacabin or portable cabin, is a prefabricated, relocatable modular structure built from a galvanized steel frame and insulated sandwich panels. It is manufactured off-site and delivered fully or partially assembled to the project location.

In the UAE, porta cabins are purpose-built for rapid deployment as:

• Site offices.
• Worker accommodation.
• Welfare facilities such as toilets, prayer rooms, and first-aid rooms.
• Storage units.
• Temporary commercial spaces such as kiosks and pop-up shops.

A proper UAE-specification porta cabin is not a basic shed, and it is not a converted shipping container left as it is. It is an engineered structure designed to be functional the same day it arrives on site, and built to survive conditions that include:

1. Sustained ambient temperatures above 48°C.
2. Sand-laden winds across desert and coastal construction zones.
3. Humidity levels along the coast that turn a poorly insulated cabin into an unbearable space within hours.

How a UAE-Specification Porta Cabin Is Built

A standard UAE porta cabin is assembled from six core components. Each one plays a specific role, and each one affects either the internal usable space or the cabin’s ability to survive UAE conditions.

1. Steel frame. Hot-dip galvanized or powder-coated structural steel, typically 2mm gauge for standard units and heavier gauge for ADNOC-spec or two-storey applications.
2. Floor. A steel deck with a polyurethane foam core, finished with vinyl sheeting, anti-slip checker plate, or cement-fibre board depending on use.
3. Walls and roof. Polyurethane (PU) sandwich panels, the single most important component for UAE heat resistance. Panel thickness directly affects usable internal area.
4. Doors and windows. Steel-framed doors with aluminum-framed windows, tinted or frosted glass, and mosquito mesh.
5. Electrical wiring. Pre-wired to UAE standard 240V single-phase or 415V three-phase supply.
6. Air conditioning. A high-ambient split unit rated for Gulf temperatures, since standard domestic units are not adequate here.

Manufacturers such as Bait Al Maha produce this full range of cabin types, from security booths to multi-room labour accommodation blocks, with these UAE-specific build standards applied as standard rather than as an extra cost.

Porta Cabin vs. Shipping Container vs. Modular Building: What Is the Difference?

Feature	Porta Cabin	Shipping Container	Modular Building
Structure	Steel frame plus PU sandwich panels	Repurposed or new Corten steel container	Engineered prefab modules with full fit-out
Customization	High	Low to medium	Very high
UAE Climate Readiness	Yes, with 75mm-plus panels and T3 air conditioning	No, requires heavy insulation retrofit	Yes
Municipality Acceptance	Widely accepted, established NOC process	Varies by site and authority	Project-specific, usually a longer approval
Delivery Time	2 to 5 days for stock sizes	3 to 7 days depending on modification	6 to 12 weeks minimum
Best UAE Use	Site offices, labor accommodation, welfare facilities	Storage, workshops, cafeterias	Semi-permanent offices, schools, medical facilities

A few quick takeaways from this comparison:

1. A modified shipping container works well for storage or workshop applications, and dedicated container conversion services exist for exactly this purpose.
2. For habitable, occupancy-compliant spaces, a purpose-built porta cabin with proper insulation is almost always the faster, cheaper, and lower-risk choice.
3. Modular buildings suit semi-permanent projects where budget and timeline allow for a longer build period.

 

The Dubai Context: Why Global Porta Cabin Size Standards Do Not Apply Here

A porta cabin size guide written for the United Kingdom, India, or the United States will not serve a UAE buyer well. The UAE combines extreme climate conditions, multiple regulatory authorities, and unique logistics constraints, and this combination makes generic global dimensions an unreliable reference point on their own.

The Climate Engineering Problem, and How It Shrinks Your Usable Space

UAE summer temperatures create a genuine structural engineering challenge, not just discomfort:

• Ambient temperatures regularly exceed 48°C in June, July, and August.
• Ground-level temperatures on exposed construction sites routinely reach 55°C to 60°C.

In these conditions, a porta cabin with inadequate insulation does not just become hot. It becomes a welfare liability. Here is the detail most suppliers never volunteer upfront: panel thickness comes directly out of your usable internal space.

Panel Thickness	Reduction Per Side	Resulting Internal Size (on a 3m × 6m cabin)	Resulting Internal Area
50mm	50mm reduction on each face	Approximately 2.9m × 5.9m	Approximately 17.1m²
75mm	75mm reduction on each face	Approximately 2.85m × 5.85m	Approximately 16.67m²
100mm	100mm reduction on each face	Approximately 2.8m × 5.8m	Approximately 16.24m²

That difference, up to 1.76m² on a single 3m × 6m cabin, is enough for an additional workstation, an extra bed, or a critical safety margin when MOHRE measures floor area per occupant.

UAE panel specification guide:

1. 50mm panels: inadequate for continuous occupation, suitable only for storage.
2. 75mm panels: the UAE’s minimum standard for any habitable cabin.
3. 100mm panels: recommended for ADNOC-specification cabins and exposed desert locations.
4. 120mm panels: a specialist option for extreme heat exposure.

The air conditioning requirement follows the same logic. A cabin that is too small cannot physically house the air conditioning capacity it needs to stay habitable. The UAE industry uses this formula as a baseline:

Cabin Volume (m³) × 650 to 750 BTU = Minimum air conditioning capacity for UAE summer conditions.

Standard domestic air conditioning units are rated for ambient temperatures only up to 43°C, which UAE summer exceeds on most days. Always specify high-ambient, T3-rated units rated to 52°C or 54°C for any UAE porta cabin. Bait Al Maha’s technical and AC installation team sizes the unit to the cabin volume at the point of order, which removes this guesswork for the buyer.

UAE Regulatory Authorities That Set Minimum Cabin Dimensions

You cannot simply pick a size and order it in the UAE. Depending on your project type and location, one or more of the following bodies will have direct authority over your cabin’s minimum size, occupancy limit, and material specification.

1. MOHRE – Ministry of Human Resources and Emiratisation

Under Ministerial Resolution No. 44 of 2022, any establishment employing 50 or more workers earning AED 1,500 or less per month must provide accommodation that meets MOHRE’s published standards. Key requirements include:

1. A minimum of 3 square meters of bedroom space per worker, with industry practice commonly applying 3.5 to 4 square meters for a safer margin.
2. A minimum bed spacing of 36 inches on all sides for single beds, and 48 inches for bunk beds.
3. A strict prohibition on three-tier bunk beds.
4. One toilet for every 8 workers sharing facilities.

MOHRE inspectors conduct both scheduled and surprise visits. Non-compliance can lead to:

• Fines ranging from AED 5,000 to AED 50,000.
• Restrictions on new work permits.
• Project suspension in serious cases.

2. Dubai Municipality (DM) and Abu Dhabi City Municipality (ADM)

Before a porta cabin can be occupied, the project must obtain a No Objection Certificate. The NOC process generally requires:

1. A site plan showing the cabin’s location.
2. The cabin’s technical specification sheet.
3. The main contractor’s project documentation.

Processing time is typically 5 to 15 working days.

3. ADNOC – Abu Dhabi National Oil Company

For any project within ADNOC’s supply chain:

• Only ADNOC-approved vendors can supply cabins for ADNOC sites.
• 100mm PU panels are effectively the standard for accommodation use.
• Cabins near process areas may require blast resistance classification.

4. Free Zone Authorities – JAFZA, KIZAD, TECOM, and Others

Each major UAE free zone runs its own regulatory environment for temporary structures, and access or permit requirements should always be confirmed with the relevant authority before ordering a cabin, not after.

UAE Site Logistics: How Your Project Location Determines What Size You Can Actually Deliver

Cabin Size	Transport Method	Crane Required	UAE Road Permit	Typical Delivery Lead Time
Up to 3m × 6m	Standard flatbed truck	Optional, forklift possible	Not usually required	1 to 3 days
3m × 9m	Standard flatbed	Recommended	Not usually required	2 to 5 days
3m × 12m	Long flatbed	Yes	Required on some UAE roads	3 to 7 days
Custom over 12m or double-wide	Specialist heavy transport	Yes	Yes, sometimes with police escort	4 to 8 weeks

Project location changes the equation more than most buyers expect:

1. Downtown Dubai active construction sites: delivery windows are typically restricted to between 10 PM and 6 AM, with a maximum width of 3m for standard road delivery.
2. JAFZA: crane vehicles must be pre-registered before entering the zone.
3. KIZAD, Abu Dhabi: wide industrial roads support larger deliveries, but a zone authority NOC is still required.
4. Remote Abu Dhabi desert sites: road access is generally flexible, but local crane availability should be confirmed early.
5. Northern Emirates (Sharjah, RAK, Fujairah): access is generally flexible, with fewer formal restrictions but fewer local crane operators for larger units.

A manufacturer with its own crane fleet, such as Bait Al Maha, which operates mobile cranes ranging from 20 to 300 tons for loading and unloading, can remove much of this logistics uncertainty from the delivery process.

 

Porta Cabin Sizes & Dimensions: The Complete UAE Reference

UAE porta cabins range from a compact 2m × 2m up to custom multi-unit complexes exceeding 200m² of combined floor area. Standard market sizes follow shipping container footprints, the 20-foot (6m) and 40-foot (12m) lengths, because these dimensions optimize transport costs on UAE roads and are pre-accepted by municipality permit processes.

Micro and Security Cabin Sizes & Dimensions

External Size (M)	External Size (FT)	Internal Usable Area	Standard A/C	UAE Applications
2m × 2m	6.5ft × 6.5ft	~3.2m²	9,000 BTU	Unmanned kiosks, parking barriers
2m × 3m	6.5ft × 10ft	~4.8m²	9,000 BTU	Single-guard entry points, toll booths
2.4m × 3m	8ft × 10ft	~5.5m²	12,000 BTU	Upgraded guard houses, reception booths
2.4m × 4m	8ft × 13ft	~7.5m²	12,000 BTU	Security supervisor rooms, dual-guard posts

Why UAE security companies prefer a 2.4m width over 2m:

1. A 2m × 2m cabin fits one chair and a small countertop, and nothing more.
2. A guard on a 12-hour UAE summer shift cannot stand, stretch, or access a toilet comfortably in that space.
3. A 2.4m × 3m cabin allows room for a proper chair, an unobstructed A/C unit, and space to add a compact toilet if required.

Dubai and Abu Dhabi-based security firms increasingly specify 2.4m × 3m as their minimum booth size for long-shift posts. Suppliers offering a dedicated security cabin range, including parking attendant and cashier cabin variants, can usually accommodate this size as a stock item.

Small Cabin Sizes & Dimensions

External Size (M)	External Size (FT)	Internal Usable Area	Max Office Occupancy	Standard UAE Applications
2.4m × 6m	8ft × 20ft	~11.5m²	2 people	Small site offices, supervisor offices
3m × 4m	10ft × 13ft	~9.5m²	2 people	Prayer rooms, small meeting rooms
3m × 5m	10ft × 16ft	~12m²	2 to 3 people	Site first-aid rooms, welfare facilities
3m × 6m	10ft × 20ft	~14.5m²	3 to 4 people	Site offices for small teams, small clinics

Why the 3m × 5m matters more than its size suggests:

1. It is the UAE industry’s practical minimum for a compliant site first-aid room.
2. It fits a treatment table, a medical cabinet, an attendant’s workspace, and clear floor access for a stretcher, all at once.
3. Going smaller usually means sacrificing one of those functions, which rarely passes a municipality inspection.

Medium Cabin Sizes & Dimensions: The UAE Construction Standard

External Size (M)	External Size (FT)	Internal Usable Area	Office Occupancy	Primary UAE Use
3m × 6m	10ft × 20ft	~14.5m²	4 to 5 people	UAE’s most common site office size
3m × 7m	10ft × 23ft	~17m²	5 to 6 people	Dual-use office with an integrated meeting area
3.2m × 6m	10.5ft × 20ft	~15.5m²	4 to 5 people	ADNOC technical rooms, wider-format applications
3m × 8m	10ft × 26ft	~19.5m²	6 to 7 people	Senior staff offices, PRO rooms

Why the 3m × 6m became the UAE’s standard porta cabin size:

1. It matches a standard 20-foot shipping container footprint.
2. UAE road widths, flatbed trailers, and forklifts are all built around 20-foot and 40-foot container handling.
3. It fits on a standard UAE flatbed truck without needing a special transport permit on most roads.
4. Dubai and Abu Dhabi Municipality have processed thousands of NOC applications for this exact size, which speeds up approvals.
5. It is the most widely stocked size in UAE supplier yards, often available within 24 to 48 hours for rental.

Four internal layout options for a 3m × 6m cabin:

1. Four-person open office with desks in two facing pairs and a central walkway.
2. Small meeting room with a central table for six and a whiteboard on the short wall.
3. Single executive office with one large desk, a bookshelf, and two guest chairs.
4. First-aid or medical room with a treatment table and clear stretcher access.

Large Cabin Sizes & Dimensions: Accommodation, Dining, and High-Capacity Applications

External Size (M)	External Size (FT)	Internal Usable Area	Labor Accommodation (MOHRE-Compliant)	Primary UAE Application
3m × 9m	10ft × 30ft	~22m²	4 to 5 workers	Medium accommodation, dining rooms
3m × 12m	10ft × 40ft	~29.5m²	6 to 8 workers (single beds)	Labor accommodation, large site offices, dining halls
3.5m × 12m	11.5ft × 40ft	~33m²	8 to 10 workers	Premium site offices, executive accommodation
3m × 15m	10ft × 50ft	~37.5m²	10 to 12 workers	Long dining halls, large accommodation blocks

The 3m × 12m is the most important porta cabin size in the UAE. It is the cabin you will see in rows across nearly every active labor camp in Dubai, Abu Dhabi, and the Northern Emirates, offering around 29.5m² of usable space with 75mm panels.

01. Six-person accommodation (comfortable, strong compliance margin).

1. Six single beds in two rows of three.
2. A personal locker at the foot of each bed.
3. A high-ambient split A/C unit on one short end wall.
4. Roughly 4.9m² of floor space per worker.

02. Eight-person accommodation (standard MOHRE-compliant).

1. Eight single beds in four pairs.
2. A 1m clear aisle running down the center.
3. Roughly 3.7m² of floor space per worker, within the MOHRE range when a fully equipped welfare block sits nearby.

03. Ten to twelve-person bunk bed accommodation (minimum compliance boundary).

1. Six bunk beds in two rows with a shared locker column.
2. Acceptable only when a fully compliant ablution block and welfare facilities are also in place.

Ablution block sizing, the number most camp managers get wrong:

UAE guidance requires one toilet per 8 workers in shared accommodation. For a standard camp using 3m × 12m accommodation cabins:

1. 40 workers: one 3m × 9m ablution cabin with 5 toilet cubicles, 5 shower stalls, and 3 wash basins.
2. 80 workers: two 3m × 9m ablution cabins, or one 3m × 12m with 10 toilets, 10 showers, and 4 wash basins.
3. 120 workers or more: multiple dedicated ablution cabins.

Labour accommodation blocks, dining halls, and prefab toilet cabins are typically supplied together as a package by UAE manufacturers, which simplifies coordination across a full camp setup.

Custom and Modular Complex Configurations

Double-wide configurations:

1. Two 3m-wide units joined along their long wall create a 6m internal-width space, similar to a proper office floor plan.
2. This gives roughly 66m² of usable area.
3. Dubai and Abu Dhabi both treat double-wide units as a separate structural category for permitting, so expect a longer NOC processing time.

Two-storey configurations:

1. A standard two-storey setup uses two 3m × 12m units stacked vertically with an external galvanized steel staircase.
2. Total height typically runs from 5.5m to 6.5m.
3. A licensed UAE structural engineer must certify the connection design and load calculations.
4. A separate municipality approval is required in both Dubai and Abu Dhabi.
5. Allow a minimum of four to six weeks for this permit.

Camp Size	Accommodation Cabins (3m × 12m)	Ablution Cabins	Dining Cabin	Site Office	Total Land Area
50 Workers	7 cabins	2 × 3m × 6m	1 × 3m × 9m	1 × 3m × 6m	~660m²
100 Workers	13 cabins	3 × 3m × 6m	1 × 3m × 12m	1 × 3m × 9m	~1,200m²

500 Workers	63 cabins	12 × 3m × 6m	4 × 3m × 12m	2 × 3m × 12m	~5,500m²

 

Exact Porta Cabin Sizes & Dimensions for Every UAE Project Type

1. Construction Site Offices in Dubai and Abu Dhabi

Direct answer: For a team of up to four people, the minimum practical size is a 3m × 6m cabin. For teams of five to ten people, the 3m × 12m is the UAE standard. Beyond ten staff, plan for a double-wide or two-storey unit.

Site Office Team Size	Recommended Cabin Size
1 to 2 people	3m × 4m or 3m × 6m
3 to 5 people	3m × 6m
6 to 10 people	3m × 9m or 3m × 12m
11 to 15 people	3m × 12m or double-wide
15 or more people	Double-wide or two-storey

2. Labor Accommodation Porta Cabins

Direct answer: The UAE standard is a 3m × 12m cabin configured for 6 to 8 workers, based on a minimum of 3 to 4 square meters of space per worker under MOHRE guidance.

A compliant accommodation facility also needs:

1. A dedicated dining or canteen area, separate from sleeping quarters.
2. One toilet and one shower per 8 workers.
3. A first-aid room for housing units above a defined size.
4. A designated prayer room and laundry facilities.

3. Oil and Gas Project Cabins for ADNOC and Offshore Sites

Direct answer: Standard sizes range from 3m × 6m to 3m × 12m, but:

1. 100mm PU sandwich panels are effectively mandatory.
2. All cabins must come from ADNOC-approved vendors.
3. Hazardous zone classification can limit cabin placement.
4. Blast resistance certification may be required near process areas.
5. Offshore weight restrictions can affect the final size chosen.

4. Event and Exhibition Temporary Cabins

Direct answer: The most common sizes are:

1. 3m × 6m for ticket offices and VIP check-in areas.
2. 2.4m × 3m for security checkpoints.
3. Up to 12m × 9m modular complexes for temporary media centers at large UAE events.

5. Temporary Classrooms and Healthcare Cabins

1. UAE private schools commonly use 3m × 9m or 3m × 12m cabins for class sizes of 20 to 30 students.
2. Classroom and laboratory cabin units are also widely used for temporary medical screening and consultation rooms.
3. A 3m × 6m is the minimum for a full clinical consultation room.

6. Retail and Commercial Pop-Up Cabins

Direct answer: Sizes range from:

1. 2.4m × 3m for coffee kiosks and ATM enclosures.
2. 3m × 9m for pop-up retail stores and temporary bank branches.
3. Commercial retail cabins typically need three-phase electrical supply, which changes the DB board specification.

 

The 5-Step Porta Cabin Sizing Framework for UAE Projects

Step 1: Define the Primary Function and Map It to the Right Authority

Primary Function	Minimum UAE Size Logic	Regulatory Authority
Site office	Staff count × 4 to 6m² each	Dubai Municipality / ADM
Labor accommodation	Worker count × minimum m² per person	MOHRE
First-aid room	Equipment footprint, staff, and clear access	DHA / DOH
Storage	Pallet count or equipment dimensions	Civil Defence
Dining / canteen	Diner count × 1.2m² per person	MOHRE
Ablution / toilet block	Toilet and shower ratio per occupant	MOHRE
Security / guard post	Shift duration and welfare compliance	Municipality / MOHRE

Step 2: Calculate Occupancy the UAE-Compliant Way

1. Office use: number of staff × 4 to 6m² per person.
2. Labor accommodation: number of workers × 3 to 4m² per person.
3. Dining or canteen: number of seated diners × 1.2m² per person.

Worked example, accommodation for 24 workers:

1. 24 workers × 3.5m² per person = 84m² required.
2. One 3m × 12m provides roughly 29.5m².
3. 84 ÷ 29.5 = 2.85, so the minimum is three cabins.
4. Practical recommendation: four cabins at six workers each, for a comfortable compliance margin.

Step 3: Deduct for Internal Fittings, the Hidden Space Killers

Fitting	Space Deduction
Split A/C indoor unit	0.3m wall length, full wall height
Electrical DB board	0.6m × 0.6m wall area
Built-in toilet or bathroom	Minimum 1.2m × 1.5m
Pantry or kitchenette	Minimum 1.5m × 0.6m counter

Practical rule: deduct 15 to 20 percent from the listed internal area to arrive at the true functional space once all mandatory fittings are installed.

Step 4: Verify Site Access and Delivery Feasibility

1. Confirm the entry gate width is at least 3.5m clear.
2. Confirm the entry gate height clearance is at least 4.5m.
3. Confirm a 5m × 5m hard-standing area exists for a mobile crane.
4. Check the delivery route for overhead power lines.
5. Confirm RTA and municipality delivery time windows.
6. Confirm any free zone vehicle registration requirements.

Step 5: Budget Against the Right Size, Not the Cheapest Size

Cabin Size	Monthly Rental (AED)	Purchase Price (AED)
2.4m × 3m (Security)	500 to 800	10,000 to 18,000
3m × 6m (Standard Office)	800 to 1,400	15,000 to 28,000
3m × 9m	1,100 to 1,800	24,000 to 38,000
3m × 12m	1,300 to 2,200	30,000 to 48,000
3.5m × 12m (Premium)	2,000 to 3,000	40,000 to 65,000

Rental versus purchase, by project duration:

Project Duration	Recommendation
Up to 6 months	Rental
6 to 18 months	Rental, negotiate a 12-month rate
18 to 36 months	Consider purchase
36 months or more	Purchase

For shorter projects, Bait Al Maha’s prefab rental solutions cover site offices, security cabins, and accommodation units across Abu Dhabi, Dubai, Sharjah, Ajman, UAQ, Ras Al Khaimah, and Fujairah, with relocation support once the project moves on.

How Cabin Materials Change Your Real Porta Cabin Size & Dimensions

The PU Sandwich Panel: The UAE’s Non-Negotiable Insulation Standard

Panel Thickness	Reduction Per Face	UAE Suitability
50mm	50mm	Not recommended for habitable use
75mm	75mm	UAE standard minimum
100mm	100mm	Premium, ADNOC-spec
120mm	120mm	Specialist use

A worked example on a 3m × 12m cabin with 75mm panels:

1. Actual internal area: approximately 33.77m².
2. Advertised area: 36m².
3. Space lost to panel depth: approximately 2.23m², roughly the footprint of a single bed.

Internal Height: Why the UAE Standard Runs Higher Than Most Markets

1. Standard UAE porta cabin internal clear height runs from 2.4m to 2.6m.
2. A 2.5m minimum is the practical target for any habitable space.
3. A 2.6m height is recommended for long-term occupation, since lower ceilings trap more heat and increase A/C load.

A/C Unit Sizing for UAE Porta Cabin Volumes

Cabin Size	Minimum BTU (UAE Summer)	Recommended Tonnage
2.4m × 3m × 2.5m	11,700 BTU	1.0 ton
3m × 6m × 2.5m	29,250 BTU	2.5 ton
3m × 9m × 2.5m	43,875 BTU	3.5 to 4 ton
3m × 12m × 2.5m	58,500 BTU	4.5 to 5 ton

Formula: internal volume (m³) × 650 BTU = minimum UAE summer requirement.

Specialist technical and AC installation services, including ducted split, decorative, and packaged A/C systems, are usually bundled with the cabin order by experienced UAE manufacturers, which avoids the mismatch between cabin size and cooling capacity described above.

 

8 Costly Porta Cabin Sizing Mistakes UAE Project Managers Must Avoid

1. Ordering by external dimensions and ignoring internal usable space. Always request the internal clear dimensions, not just the catalogue size.
2. Ignoring MOHRE occupancy ratios before finalizing headcount. Apply the occupancy formula from Step 2 before finalizing any accommodation order.
3. Choosing the smallest cheap option, then adding external accessories. Map every required function before selecting a unit.
4. Not confirming delivery logistics before placing the order. Run the site access checklist from Step 4 before ordering, not after.
5. Forgetting the A/C unit’s physical footprint in the layout. Request a to-scale floor layout drawing before confirming the configuration.
6. Specifying standard panels instead of UAE-grade high-ambient material. The panel upgrade cost is far lower than the cost of an early A/C replacement.
7. Not planning for modular expansion. Order all cabins from the same supplier with compatible joining provisions if growth is even a possibility.
8. Comparing quotes without comparing specifications. Always compare the full specification sheet, not just the headline price.

 

What UAE Porta Cabin Suppliers Won’t Always Tell You

Stock Sizes vs. Manufactured Sizes

1. Stock sizes, such as the 3m × 6m and 3m × 12m, are usually delivered in 1 to 3 days.
2. Near-stock sizes, such as the 3m × 9m, take 1 to 2 weeks.
3. Custom manufactured sizes typically take 4 to 8 weeks from UAE-based manufacturers, and 8 to 14 weeks if imported.

Eight Questions to Ask Any UAE Porta Cabin Supplier

1. Are the dimensions you have quoted internal or external?
2. What is the PU panel thickness on the walls, roof, and floor?
3. What is the A/C unit brand, model, and BTU rating?
4. Can you provide municipality-ready drawings for NOC submission?
5. What is the steel frame gauge, and is this cabin suitable for two-storey stacking?
6. Is the cabin pre-wired, and what is the DB board’s load capacity?
7. What does your warranty cover, and for how long?
8. Can this cabin be joined to another unit later?

A manufacturer that builds and supplies directly, rather than reselling, will usually answer all eight without hesitation. You can review completed labour camps, site offices, and accommodation projects on Bait Al Maha’s project portfolio before requesting a quote, or reach out directly through the contact page with your floor area and occupancy numbers ready.

How tall is a standard porta cabin?

Standard internal height runs from 2.4m to 2.6m, with 2.5m as the recommended minimum for comfortable, compliant habitable use.

Final Thoughts on Choosing the Right Porta Cabin Size & Dimensions

Porta cabin sizing in the UAE is not a commodity decision. It carries direct consequences for regulatory compliance, worker welfare, delivery logistics, and total cost over the life of the project.

Five things that will keep your porta cabin selection on the right track:

1. Define the function before you define the size, since every use case maps to a different regulatory authority.
2. Calculate occupancy the way MOHRE and the municipalities calculate it, using floor area per person rather than physical fit.
3. Deduct for fittings before finalizing, taking 15 to 20 percent off the listed internal area.
4. Verify site access before placing the order, not after.
5. Specify UAE climate-grade materials, since 75mm PU panels and T3-rated A/C units are the non-negotiable baseline in this climate.

The information in this guide reflects UAE industry standards and publicly available regulatory guidance from MOHRE, Dubai Municipality, Abu Dhabi City Municipality, and ADNOC. Regulations do change, so always verify current requirements with the relevant authority for your project type.

If you are still working out the right porta cabin size and dimensions for an upcoming project, here are three easy next steps:
