ISO Frame | Construction-sector accommodation

Modular site accommodation with a fully furnished 45m² apartment layout

Combine two ISO Frame modules into a fully furnished apartment for construction staff and project teams. The brief specifies a 45m² apartment, with the final rooms, occupancy, furniture and service requirements coordinated around the intended site and use.

This is an accommodation product within the wider construction-site building range. Welfare units, offices and storage containers can be discussed alongside the apartment, but they are separate products rather than automatic inclusions in the two-module package.

The ISO Frame master specification offers Standard, REI60 fire-rated and higher-performance energy packages. Their different wall, roof, floor, opening and heating specifications are set out separately below. The selected package must be identified in the quotation; its suitability for sleeping accommodation is reviewed for the actual project.

The fully furnished modular apartment is not presented as an empty shell. Its furniture inventory, kitchen and bathroom arrangements, hot-water provision and appliance schedule must nevertheless be agreed because the supplied master specification does not identify those items or quantities.

The steel-frame system supports transport and future relocation, subject to the selected configuration, lifting plan and receiving site. Two modules do not establish a bedroom count or a two-storey arrangement.

Explore ISO Frame systems and discuss separate welfare units when planning the wider site compound. The apartment and companion buildings are scheduled individually in the project quotation.

Applications and layout options

Construction projects

Construction Worker Accommodation

A two-module apartment brief for construction staff working away from their usual base. Final occupancy, room arrangement and the sleeping-accommodation approval route are established for the proposed site.

Staff living space

Fully Furnished Modular Apartment

A furnished accommodation package rather than a basic site office. The room plan and inventory define the furniture, storage, kitchen, bathroom and appliance arrangements actually supplied.

Longer project deployments

Relocatable ISO Frame Accommodation Unit

An ISO Frame accommodation unit can be planned around a project deployment and possible later relocation. Transport, lifting, services and the receiving site are reviewed for each move.

Wider site compound

Accommodation, Welfare & Storage Planning

Coordinate the apartment enquiry with separately specified welfare units, site offices and storage containers. Their layouts, loading requirements, quantities and prices remain separate from the apartment specification.

Frequently asked questions

What is this modular site accommodation product?

It is a fully furnished apartment formed from two ISO Frame modules, with a stated area of 45m², proposed for construction-sector staff accommodation. The final layout, package, occupancy and site requirements are agreed before manufacture.

Does two modules mean two bedrooms?

No. Two modules describes the construction format. The supplied brief does not state the bedroom count, bed spaces or permitted occupancy, so these must be confirmed on the floor plan.

Is 45m² the usable internal area?

The brief states a 45m² apartment but does not define the measurement basis. Gross external footprint, usable internal area and individual module dimensions must be confirmed by the drawing.

What does fully furnished include?

Fully furnished is part of the apartment brief. The exact furniture, storage, kitchen, bathroom, appliance and hot-water schedules must be agreed because the master specification does not provide an itemised apartment inventory.

Which ISO Frame package is included?

No package has been selected in this unpriced configuration. The quotation must identify Standard, REI60 or the higher-performance energy package, or a separately documented combined specification.

What is the Standard ISO Frame construction?

The supplied Standard package uses a bolted steel frame, 80 mm mineral-wool walls, a roof with 100 mm mineral wool and a floor with 100 mm mineral wool and 22 mm P5 chipboard. Its standard finish is 2 mm grey commercial PVC flooring.

Does the apartment include heat-pump heating and cooling?

The Standard package specifies convector heaters. An air-to-air heat pump with a stated SCOP of 4.5 is listed for the higher-performance energy package. The ordered heating system must therefore be confirmed rather than combining both descriptions.

Is REI60 fire resistance standard?

No. REI60 is a separate fire-rated variant in the master specification, with different frame and envelope details. The final apartment needs matching supporting documentation and a project fire strategy; the package name is not an independent approval for the joined building.

Can REI60 and the energy package be combined?

A combined requirement can be reviewed, but the supplied specification does not establish a single construction that automatically achieves both. The agreed build-up needs coordinated structural, fire and thermal evidence.

Is the higher-performance package automatically approved for an apartment?

No. The supplied package is described against non-domestic Part L 2021 requirements. The dwelling or other sleeping-accommodation classification and applicable requirements must first be confirmed. An A-rating also requires the relevant assessment rather than being inferred from insulation thickness.

What glazing is specified?

Standard PVC windows have a stated U-value of 1.1 W/m²K, without a specified pane count. The higher-performance package lists double glazing and 0.5 W/m²K for windows and glazed doors. That lower figure needs supporting product data and confirmation of whether it refers to the complete window or door, or glazing alone.

Can the apartment be relocated or stacked?

Relocation is part of the ISO Frame system concept, subject to the actual building and site. The source describes Standard units as stackable up to three floors and REI60 units up to two. Neither system limit is an automatic stacking approval for this two-module apartment.

Are storage containers and welfare units included?

No. They are separate companion products for the wider construction site. Their quantities, floor loads, fit-outs, delivery and prices are agreed separately from the furnished apartment.

Is the apartment a substitute for site welfare provision?

Do not assume that an apartment alone covers the welfare needs of the whole workforce. Assess the site requirements separately; HSE construction welfare guidance explains the facilities to consider.

Does the wider entrance door make the apartment accessible?

The source offers a 1150 × 2100 mm glazed door described as a DDA option. Accessibility also depends on clear opening dimensions, thresholds, approach, internal circulation and the facilities, so it must be reviewed for the complete layout.

Are delivery, assembly and mains connections included?

No inclusion has been established in the supplied brief. The quotation will separately identify transport, offloading, joining, on-site assembly, final connections and any client works.

What is the price and lead time?

Neither a price nor a product-specific manufacturing or delivery period has been supplied. Request a quotation with the chosen package, accommodation layout, furnishings, postcode and target date.

Are the ISO certificates held by KC Cabins Solutions Ltd?

The listed management and manufacturing systems refer to the ISO Frame production partner. They must not be interpreted as certifications held by KC Cabins Solutions Ltd unless the company is expressly identified as the certificate holder. Current holder, scope and validity must be verified from the relevant documents.

Specify your 45m² modular site accommodation

Send your site postcode, proposed use, required occupants and rooms, furnishing needs, preferred construction package and target delivery date. List any separate welfare units, offices or storage containers so the wider site scope can be quoted clearly.
