OCM Compact Two-Bedroom Expandable Container Home with Restroom for Small Site Housing and Granny Flat Projects

Area note: Expanded external footprint and estimated internal floor area are different measurements. Occupancy figures are planning references only, not certified maximum capacities. Confirm all final dimensions, clearances, facilities and applicable local requirements against the approved drawing.

1. Shared sleeping accommodation

Two bedrooms allow occupants to sleep separately rather than sharing one large sleeping space. This may suit small teams, siblings or a small household when the rooms have appropriate dimensions and privacy. The buyer should check whether the restroom is directly accessible from the common circulation area and whether the layout supports the intended schedule of use.

2. Temporary or rotating staff accommodation

Projects with rotating teams may value the straightforward arrangement of two bedrooms and a restroom. Before deciding on occupant numbers, review the rest of the site's welfare facilities, including meal preparation, laundry and any shared kitchen. Provide enough personal storage and keep entrance and restroom routes clear for people coming and going at different times.

3. Guest accommodation with shared external amenities

On some properties, a sleeping unit may use shared dining or kitchen facilities elsewhere on site. This model can be evaluated for that scenario when the project has a convenient, weather-appropriate route to those amenities. Operators should state the location of shared facilities clearly and check local rules on sanitation, fire safety, accessibility and guest occupancy.

4. Rural or recreational plot

A compact unit can provide two separated sleeping spaces for a property where the main cooking facilities are in another building. This arrangement should only be selected after confirming utilities, wastewater, access and local approval. Consider outdoor circulation, lighting and safe movement between buildings if occupants will use a shared kitchen after dark or in poor weather.

Practical application planning: If the unit relies on a shared kitchen elsewhere, show that building and the walking route on the site plan. A nominally low-cost layout may be less practical if occupants must travel a long distance for meals or in poor weather. Confirm the project's shared facilities, access hours and lighting before selecting a sleeping-focused module.

Operational considerations for this use case: For two bedrooms with a single restroom, capacity planning needs to take the shared facility into account. Think about the timing of use, storage of toiletries, ventilation and cleaning access, especially for workers or guests. The final number of occupants should be based on the actual arrangement and applicable rules rather than simply the number of beds that could physically fit.

(1) Separate sleeping rooms without a large floor plate

The two-bedroom arrangement supports personal space while keeping the external dimension family compact. The practical trade-off is that each bedroom and the shared circulation must fit into the available internal area. Review clear room dimensions and bed placement rather than judging suitability by the bedroom count alone.

(2) Restroom provision addresses a key daily need

An internal restroom helps make the unit more independent than a simple room module. Its usefulness depends on fixtures, ventilation, waterproofing and a workable wastewater connection. Buyers should ask for a fixture list and service drawing, particularly when the destination has limited utilities or strict sanitation requirements.

(3) A simpler scope when a kitchen is not needed

Not including a kitchen may suit projects where meals are prepared in a shared facility or where the main task is overnight accommodation. This can leave more scope for sleeping and movement, depending on the chosen design. If cooking is required later, discuss the changes before ordering rather than assuming a kitchen can be added without affecting services and layout.

(4) Compact layout encourages disciplined furniture planning

A carefully selected bed size, wardrobe arrangement and storage plan can make a smaller two-bedroom home easier to use. Avoid placing cabinets where they obstruct window access or narrow the restroom route. A full-scale furniture drawing helps resolve such details before manufacturing.

(5) Additional value for project buyers

The main advantage is a clear separation of sleeping rooms and an internal restroom without requiring the project to include a kitchen in every unit. This can be appropriate where a site already has a shared dining or meal-preparation facility. The key is to make that operating assumption explicit so the layout is not sold as more self-contained than it is.

(6) Long-term planning value

A compact plan can be easier to repeat across small accommodation sites where each unit serves the same basic purpose. A standard furniture list, room drawing and restroom maintenance routine help reduce operational variation. Site approvals and the availability of shared facilities must still be confirmed for each destination.

# Layout, room use and occupancy planning

Start by confirming whether occupants will prepare food in this unit or use facilities elsewhere. If there is no kitchen, plan a suitable place for everyday items and confirm how residents move to the shared cooking area. For the restroom, check door swing, fixture clearance, ventilation and maintenance access on the drawing.

Use two-to-four occupants only as a starting point. The appropriate number depends on actual bed layout, room dimensions, sanitary capacity and local requirements. For a worker or guest project, check relevant accommodation rules and emergency egress requirements before assigning room capacity.

The estimated internal area is 34.5 m²; this does not replace clear room measurements. The final number of occupants must match the approved bed plan, sanitary provision, circulation, local requirements and the way the unit will be used.

Site Preparation & Installation

# Site preparation, delivery and installation

The installed unit needs a prepared support base, clear expansion zone, weather drainage and correctly placed utilities. If cooking amenities are off-site, make sure the property plan accounts for safe and practical access to them. Have local professionals check structural, electrical and sanitation provisions as required.

After expansion, inspect the restroom and test all utility connections before occupancy. Local inspection, fire-safety and accommodation requirements vary by destination; agree who manages these checks and who completes any locally required work.

Folded transport dimensions: 2200 × 5900 × 2480 mm. Expanded external dimensions: 6300 × 5900 × 2480 mm. Confirm the final packaging data, unloading arrangement, support-base details and utility responsibilities before shipment.

Q1: What is the standard layout for this unit?

The reference arrangement is: 2 bedrooms + 1 restroom; a kitchen is not included in the stated layout unless expressly added. Review the approved floor plan for actual room dimensions, partition positions, door swings, windows and circulation. Product images can show a sample arrangement and should not replace the drawing attached to your quotation. If a room or facility is essential, make sure it appears by name and position in the final specification.

Q2: Which sanitary or kitchen facilities should I specify?

The stated layout includes a kitchen and restroom. For the specified layout (2 bedrooms + 1 restroom; a kitchen is not included in the stated layout unless expressly added.), confirm the exact fixture package, cabinetry, appliances, hot-water equipment and utility connections in the approved quotation. Please identify every required item before production. If the project needs an independent kitchen or a complete bathroom, ask for a drawing and inclusion list showing the fixture arrangement, water and wastewater points, ventilation and electrical provisions.

Q3: What occupant number should I use for early planning?

For early planning, use this guide: 2–4 people as a preliminary guide; review room size, bathroom access and local occupancy rules. It is not a certified capacity or a promise of legal occupancy. For a project centred on two sleeping rooms and one restroom in a compact layout, occupant planning must account for bed arrangement, furniture, ventilation, restroom capacity, movement space and the destination's applicable rules. Tell us how the unit will be used so the proposed layout can be assessed more accurately.

Q4: How much interior area does the expanded unit provide?

Using the listed internal length and width for the 20ft expandable container house, the estimated internal floor area is about 34.5 m². The expanded external footprint is about 37.2 m², which includes the external dimensions rather than only the interior. These figures are estimates for comparing the two sleeping rooms and one restroom in a compact layout concept; the final room drawing should be used to confirm clear dimensions before furniture is specified.

Q5: How should the base and service routes be prepared?

The site needs an appropriate support base, a clear delivery and unloading route, space for the expansion sequence, drainage and planned utility routes where required. Foundation design depends on ground conditions, engineering and local requirements. Provide the site plan to the installation team and compare it with the supplier's instructions before arranging delivery or preparing the support base for two sleeping rooms and one restroom in a compact layout.

Q6: Can installation time be guaranteed?

The expandable construction is intended to reduce some on-site assembly compared with building every component on location, but no fixed completion time should be assumed from the product category alone. Timing depends on the prepared base, lifting equipment, crew, weather, services, final fit-out and inspection. Ask for a project-specific installation sequence and confirm which activities are included in the supplier's scope.

Q7: How do I choose an insulation core for the destination?

Listed insulation-core options include EPS, rock wool and PU. The suitable choice depends on destination climate, intended use, project specification, local regulations and the full wall/roof assembly. Ask OCM to confirm the material, thickness and relevant technical documents for the exact order. Do not treat the material name alone as proof of a particular fire, thermal or acoustic rating.

Q8: How should I request layout changes?

Layout discussions can be based on the intended occupants, use of the rooms, preferred openings, facilities, storage and site conditions. Changes must be reviewed for technical feasibility and confirmed by OCM on an approved drawing. For this 20ft expandable container house, do not assume every requested change is available as standard or that it leaves the reference dimensions unchanged; confirm any effect on folded size and transport.

Q9: Which size is relevant to freight and access checks?

Use the listed folded transport dimensions for initial logistics review: 2200 × 5900 × 2480 mm. The completed external dimensions are 6300 × 5900 × 2480 mm; the installation site must accommodate the expanded form and the space required to open the unit. Ask for final packing dimensions, gross weight and loading advice for the actual order before freight is booked.

Q10: How do I confirm shipment and packaging details?

OCM's sea-export packing description includes moisture-resistant wrapping and anti-collision protection; confirm the actual package for your order. The exact package, loading arrangement and included components must be confirmed for the order. Before shipment, ask for the packing list, folded dimensions, shipping weight, loading plan and any required documents. The freight forwarder should evaluate the actual cargo data and destination constraints.

Q11: How can I verify the specification for my destination?

Requirements depend on the destination, intended occupancy and whether the unit is used as a residence, guest accommodation, workplace or public facility. Before purchase, check planning permission, structural design, fire safety, energy performance, sanitation, electrical work and occupancy rules with relevant local professionals or authorities. Any product-specific certificates or reports should be verified for the actual model and market.

Q12: What should I provide for a project quotation?

Please share the destination country, intended use, quantity, preferred layout (2 bedrooms + 1 restroom; a kitchen is not included in the stated layout unless expressly added.), target occupants, insulation preference, door/window requirements, required kitchen or restroom facilities and any site-access limitations. A site sketch or photos can help where delivery access is difficult. Ask for a dimensioned drawing, material list, package details, included/excluded items and confirmation of the final configuration before ordering.
