Classic Garden Room A3 Steel Frame

The listed overall dimensions are 4850 × 2400 × 2130 mm. Insulation, cavities, linings, roof and floor build-ups affect finished usable dimensions, so the supplied project drawings govern the final layout.

The dimensions produce an approximate structural footprint of 11.6 m². This is a simple width-by-length comparison figure, not confirmed finished internal floor area.

The published listed weight is 552 kg. Delivery, unloading, panel handling, lifting, storage and the route from the delivery point to the foundation must still be planned for the site.

No separate opening schedule is published in the source listing. Confirm every opening in the supplied project drawings.

No. It is listed as a classic garden-room frame. Foundations, erection, floor, insulation, membranes, roof, cladding, glazing, services and internal finishes are separate unless the written Forti Nova quotation includes them.

A change may require another published frame or a bespoke design. Structural dimensions, members and openings must be confirmed in approved project drawings before manufacture and must not be altered on site without approval.

No. The displayed figure is the online frame price only. Forti Nova confirms availability, VAT basis, delivery, drawings, included services and exclusions in writing.

Yes, subject to assessment. Ground screws start from £65 + VAT per screw and professional frame erection starts from £1,250 + VAT. Ground conditions, screw type and quantity, structural loads, postcode, access, frame design and programme determine the final quotation.

Send the project postcode, intended use, access photographs, required clear dimensions, door and window requirements, foundation status, target programme and whether you need frame-only supply, erection, ground screws or exterior materials.

No. The final supplied drawings, structural information and written quotation take priority over the online summary for setting out, manufacture, openings, connections, assembly and responsibility boundaries.

No approval is implied by a catalogue listing. Building Regulations can depend on floor area, intended use, sleeping accommodation, proximity to boundaries, construction and services. Obtain project-specific professional and local-authority advice where required.

Estimated delivery is 2–4 weeks from order. The confirmed programme is stated in writing and can depend on approved details, manufacturing capacity, location, access and any bespoke requirements.

The payment schedule is 30% deposit on ordering, 40% during manufacture and the final 30% before delivery. The written order and quotation confirm the amounts, VAT and due dates.

Professional frame erection starts from £1,250 + VAT. The final price depends on the selected frame, foundation readiness, postcode, access, unloading, lifting and programme.

Suitable ground screws start from £65 + VAT per screw. The final screw type, length, head, quantity, layout and installation cost depend on the ground, structural loads, levels, access and project design.

The published A range uses a 2400 mm structural depth; the B range uses a 2900 mm structural depth. Widths progress across A1–A4 and B1–B4. Compare footprint and finished usable space, then confirm the final choice from project drawings.

The published footprint is an external structural comparison, not finished internal floor area. Continuous insulation, service cavities, membranes, battens and internal linings reduce the clear space. Forti Nova can only confirm usable dimensions from the agreed wall, floor and roof build-ups.

Neither material is automatically right for every project. Light-gauge steel offers dimensional accuracy, low structural weight and resistance to rot and insects. Timber can be familiar to local trades and may simplify some thermal details. Steel still needs careful insulation, thermal-bridge control, condensation design and corrosion-appropriate detailing.

No. Year-round performance comes from the complete building system: continuous insulation, controlled thermal bridging, airtightness, vapour and moisture management, ventilation, suitable glazing, heating and correctly detailed floor, wall and roof junctions.

Supply-only can suit competent customers working to the approved drawings with suitable handling equipment and a verified foundation. Do not alter structural members or openings on site without approval. Forti Nova also offers professional erection from £1,250 + VAT.

Yes. Bespoke dimensions, openings or other changes may be available and may incur additional design, engineering or manufacturing costs. Feasibility and price are confirmed before order.
