KC Bespoke | Portable cabin | 22.05m²

A 7m × 3.15m portable cabin for a dedicated workspace

Create a separate space for office work, project administration or a home workspace with this 7m × 3.15m portable cabin. The insulated steel-frame package includes finished SPC flooring, triple-glazed laminated windows and aluminium entrance doors, with the working layout and services agreed for your site.

The supplied overall dimensions give a 22.05m² footprint. The 7m-long rectangular plan can be arranged around desks, storage and circulation once the finished internal dimensions are established. No workstation count, partition layout or usable-area figure is implied by the external size.

The confirmed building price is £21,000 + VAT. This is a purchase offer for the specified KC Bespoke cabin, not a hire rate, a furnished accommodation package or a ready-connected office. Delivery, offloading, lifting, assembly and service inclusions are agreed before the complete order total is confirmed.

The cabin retains the same material specification as the 4m × 4m KC Bespoke garden office pod: high-strength closed steel profiles, Kingspan KS1000/1150 TL panels or an agreed equivalent, Protan SE 2.0 membrane, an 18mm cement-bonded chipboard floor deck and Class 42 SPC flooring. The new dimensions and price do not introduce the MB24 ISO Frame build-up.

The supplied insulation basis is 0.18 W/m²K for the wall, roof and floor specification. UPVC windows are specified at 0.9 W/m²K with triple glazing and laminated safety glass; aluminium entrance doors are specified at 1.1 W/m²K. Each selected assembly and opening needs supporting project documentation.

For a portable office cabin, agree power points, lighting, internet, heating and ventilation around the work pattern. These services are not itemised in the inherited building specification. Insulation alone does not establish a year-round temperature guarantee or an operating-cost saving.

Portable refers to planned modular transport and installation, not a wheeled or road-towable unit. Any future relocation requires a review of the structure, connections, lifting details, condition and receiving site, with a separate quotation.

Browse site and project offices or the KC shop, and download the KC Bespoke Collection catalogue (PDF). The specification and quotation for this 7m × 3.15m cabin govern its inclusions.

Frequently asked questions

How much is this 7m × 3.15m portable cabin?

The confirmed building price is £21,000 excluding VAT, or £25,200 including the configured 20% VAT. Delivery, lifting, assembly and the complete services package need to be agreed before an installed-project total is confirmed.

What is the footprint and usable internal area?

The stated overall size is 7.00m × 3.15m, giving a calculated footprint of 22.05m². Internal dimensions and usable floor area depend on the final wall build-up and layout. No desk or occupancy count is stated.

Does it use the same specification as the 4m × 4m garden office pod?

Yes. The material package is retained, including the steel frame, specified insulated envelope, Protan SE 2.0 membrane, 18mm cement-bonded chipboard deck, Class 42 SPC flooring, aluminium doors and triple-glazed laminated UPVC windows. Dimensions, structure and opening schedules must suit this cabin.

What insulation and U-values are specified?

Kingspan KS1000/1150 TL panels or an agreed equivalent are retained under the combined wall, roof and floor heading, with a specified 0.18 W/m²K basis for each completed assembly. Panel thicknesses are not supplied. Window U-value is specified at 0.9 W/m²K and entrance-door U-value at 1.1 W/m²K.

Does this portable office cabin include finished flooring?

Yes. The specification includes Class 42 SPC rigid-core vinyl flooring over an 18mm cement-bonded chipboard deck and insulated steel floor system. Select the agreed texture and finish before manufacture.

Are windows triple glazed?

Yes. Multi-chamber UPVC windows with triple glazing and laminated safety glass are specified. Opening types, dimensions, quantities, positions and safety details follow the approved schedule. This does not automatically specify triple glazing for the entrance door.

Are electrics, lighting and heating included?

They are not itemised in the inherited specification. Confirm wiring, sockets, distribution, lighting, testing, heating, cooling, ventilation and data before purchase. A convector or heat pump is not automatically included.

Is delivery or assembly included in £21,000 + VAT?

Their price inclusion has not been confirmed. Agree the destination, transport, lifting, unloading, assembly and all charges in writing. Zero delivery amounts in the configuration must not be advertised as free shipping.

What must be prepared before installation?

Agree the foundation or support design, vehicle and lifting access, utility interfaces and any site segregation before delivery. Groundworks and final mains connections are not itemised in the supplied building package.

Is this an ISO Frame container or an MB24 unit?

No. This listing uses the KC Bespoke specification inherited from the garden office pod. It does not copy the MB24 mineral-wool build-ups, handling points, stacking capability, electrical package or dimensional schedule.

Can the portable cabin be relocated?

A future move can be planned subject to structural design, condition, connections, approved handling arrangements, route and receiving-site review. It is not a wheeled or towable cabin. Later relocation is a separate project and cost.

Is this portable cabin available to buy or rent?

This listing offers purchase at £21,000 + VAT. No hire rate, rental term or finance plan has been supplied, so it is not advertised as a rental product.

Can it be used as residential or sleeping accommodation?

The proposed uses are office, project administration and home working. No bedroom, bathroom, kitchen or residential approval is included. A different use needs a separately agreed design, services and approval review.

Does a portable cabin need planning or Building Regulations approval?

Check both routes for the actual site and use. Portability does not itself establish an exemption. Consult planning-permission guidance and Building Regulations guidance, then confirm the position for the relevant UK jurisdiction.

Is the cabin soundproof, fire certified or automatically A-rated?

No whole-building soundproofing, fire certificate or issued A-rated EPC is supplied. The panel fire and acoustic references require matching documentation, while the optional energy objective and applicable Part L requirements depend on the final project.

Can I customise the portable office cabin layout?

Opening positions, finishes and working layout can be developed within the approved structural design. Internal partitions, additional services or changed materials need an explicit scope and price agreement before manufacture.

What is the lead time and where can I see other cabins?

No fixed lead time is supplied. Confirm dates after the specification and site review. Browse site and project offices or download the KC Bespoke Collection catalogue (PDF). Wider-range examples do not add inclusions to this cabin.
