MB24 | ISO Frame | Site & project offices

Portable office site cabin for construction and project teams

The MB24 provides a defined office space in a nominal 24ft × 8ft ISO Frame unit. Its mineral-wool insulated walls, roof and floor, wipe-clean internal steel panels, grey PVC floor and convector heating form the supplied base specification for site administration and day-to-day project work.

The external footprint is approximately 17.83m². The supplied internal dimensions give approximately 15.64m² of rectangular floor area before deductions for fittings or any agreed partitions, with a stated internal height of 2.50m. Plan desks, circulation and storage within those internal dimensions rather than the nominal external size.

The MB24 portable office site cabin is priced at £13,995 + VAT. This is a cabin purchase offer, not a weekly hire rate. Delivery, offloading, lifting and any site installation are confirmed for the destination before the order total is agreed; no included-delivery promise has been supplied.

The model uses the product-specific mineral-wool construction sheet: 80mm walls, 100mm roof and floor insulation, a 12mm roof liner and a 22mm P5 floor deck. The specification is not the KC Bespoke nursery package and does not automatically include PIR panels, SPC flooring, triple glazing or heat-pump cooling.

Electrical installation and convector heating are listed, but the drawing controls quantities. The sheet specifies 230V sockets alongside a 400V/5P/32A external connection and fluorescent lighting. Confirm the destination-specific electrical schedule and completion records rather than assuming a domestic plug-in connection or LED equipment.

Browse site and project offices or the modular building shop to compare alternatives. For a different construction range, download the KC Bespoke Collection catalogue (PDF); it is not the technical specification for this ISO Frame cabin.

Frequently asked questions

What is the MB24 portable office site cabin?

MB24 is a nominal 24ft × 8ft office cabin in the ISO Frame modular system. The supplied package includes mineral-wool insulation, grey PVC flooring, glazed openings, scheduled electrical installation and convector heating. It is not the KC Bespoke nursery specification.

How much does this portable office site cabin cost?

The stated MB24 cabin price is £13,995 excluding VAT, or £16,794 including the configured 20% VAT. Delivery, offloading, lifting and any on-site work must be agreed before confirming the complete installed-project total.

What are the exact external and internal dimensions?

The supplied external dimensions are 7314mm long × 2438mm wide × 2800mm high. Internal dimensions are 7084mm long × 2208mm wide × 2500mm high. These millimetre dimensions take precedence over the rounded 24ft × 8ft designation.

How much floor space does the cabin provide?

The external footprint calculates to 17.831532m², displayed as approximately 17.83m². Multiplying the stated internal length and width gives 15.641472m², displayed as approximately 15.64m² before deductions for equipment or any partitions. No desk or occupancy count is assigned.

What insulation and flooring are specified?

Walls have 80mm mineral wool; the roof and floor each have 100mm mineral wool. The floor has a 22mm P5 chipboard deck and 2mm grey PVC covering with welded joints. PIR, SPC flooring and nursery-specification build-ups are not substituted.

Are the roof and floor loading figures confirmed in the sheet?

The source states a roof load capacity of 1.6 kN/m² and a floor load capacity of 200 kg/m². Their application must be checked for the actual loading and site conditions. No higher floor-load figure, point-load rating or stock-storage rating is supplied.

Which doors and windows are supplied?

The sheet specifies a PVC single glazed door at 1150 × 2050mm according to the drawing, with lock, three keys, handles, closer and fanlight provision. It also lists a 935 × 1295mm tilt-and-turn window with an external blind and fixed panoramic glazing with notation 1130/1150 × 2420mm without an external blind. Exact quantities and the applicable panoramic width follow the approved drawing.

Is the glazing double or triple glazed?

The MB24 source describes insulated glazing but does not establish pane count, U-value or a laminated/toughened specification. These must be confirmed from the selected glazing schedule. No double- or triple-glazing claim is imported from another model.

Does MB24 include electrical installation and heating?

Yes, these are listed in the supplied specification: concealed/covered wiring, a distribution panel, 230V sockets, scheduled lighting and electric convector heating. Quantities, heater outputs and the destination-specific installation are confirmed on the drawing and electrical schedule.

Does it use a simple 230V plug connection and LED lighting?

That is not what this sheet states. It lists 230V sockets but a 400V/5P/32A external socket-and-plug connection. Lighting is described as IP65 fluorescent luminaires with 2 × 18W lamps. Confirm any alternative supply or LED substitution in writing rather than assuming either is included.

Are the interior images proof that the electrics are finished?

No. The supplied interior images show loose cables and incomplete fittings. They illustrate a fit-out stage, not completion, testing or readiness for occupation. The final supplied condition and completion documents must match the written order.

Can the cabin be moved using forklift pockets or standard ISO openings?

The source explicitly states no forklift pockets and corner transport handles with no ISO openings. Agree a suitable approved lifting method using the model-specific handling information. The ISO Frame product name does not change those source limitations.

Can this 24ft site office be stacked?

The manufacturer system sheet describes stacking up to three floors. This listing prices one cabin, not a multi-storey arrangement. Stacking requires an approved structural/support design, module connections, access, escape arrangements and a separately defined installation scope.

Is delivery or installation included in £13,995 + VAT?

The current brief does not specify those inclusions. Confirm delivery, unloading, cranage, any assembly and final connections with the site quotation. Zero delivery fields must not be used to advertise free transport.

Does the cabin include a WC, kitchen or furniture?

No WC, kitchen, plumbing, furniture or IT package is itemised in the supplied MB24 specification. These would need an expressly agreed design and quotation. It is an office cabin, not an all-in-one welfare offer.

Does the manufacturer standards list certify KC Cabins Solutions Ltd?

No. The references relate to the manufacturer and manufacturing scope. The sheet mentions management and fabrication standards and a CE declaration of performance, but actual certificates and declarations must identify their holder, scope and applicable product. No KC-held certificate is asserted here.

What is the lead time?

No manufacturing or delivery programme is supplied for this listing. Dates, availability and handover arrangements are confirmed after the specification and site review; no immediate-stock or fixed-week promise is made.

Where can I compare site offices or view the catalogue?

Browse site and project offices and the KC shop. The KC Bespoke Collection catalogue (PDF) covers an alternative range, not the MB24 ISO Frame technical specification.
