NOOK Base | 9.75m² Insulated Prefab Garden Room

In most cases, no. A 9.75m² NOOK Base is classified as a non-permanent installation with a reversible helical-pile foundation. Requirements vary by local authority, but most areas allow structures under 10m² under Permitted Development or equivalent rules. We provide every technical document you need (dimensions, materials, foundation specs) so your local authority can sign off quickly.

A fully insulated NOOK Base starts from a price that reflects premium materials, real foundation work, and turnkey installation. Unlike stick-built garden rooms where the price excludes delivery, foundations, and electrics, every NOOK price includes the helical-pile foundation, crane placement, transport, electrical pre-wiring and a 3-year warranty.

Yes. NOOK Base uses 80mm multilayer rock wool insulation in walls, floor and roof — thicker than most garden offices on the market — plus double-glazed safety-tempered PVC windows and an EPDM waterproof membrane. The result is an officially certified Energy A rating: comfortable in summer without air conditioning, and warm in winter with a modest heater. Optional climate control is available for extreme climates.

Factory manufacturing takes 8–10 weeks. The foundation (helical piles) is installed in half a day, typically two weeks before delivery. On delivery day the fully assembled unit is placed by crane and connected to utilities in under 24 hours. Total order-to-move-in timeline is 8–12 weeks, versus 3–6 months for traditional garden rooms built on-site.

A helical-pile screw foundation — included in the turnkey price. Piles are driven into the ground by machine in half a day, with no concrete pouring, no excavation, and no civil works. This means the installation is fully reversible: you can remove or relocate the NOOK without permanent land impact, a major advantage versus concrete-slab competitors when you sell or move.

Yes — it's designed for all three and more. 9.75m² with 2.5m interior height gives you a dedicated working space with no distractions, a fully insulated gym free of noise transfer to the main house, or a creative studio bathed in natural light. Configure it with the integrated NOOK Work rotating desk, Play bench-sofa, or Sleep extendable bed depending on your use case.

NOOK Base is engineered for 25+ years of durability. The reinforced steel frame doesn't rot or warp, the 50mm high-density sandwich-panel cladding resists UV and moisture, and the EPDM roof membrane carries a long-term manufacturer warranty. Heat-treated wood exteriors need light re-lacquering every 5 years; Millboard composite exteriors are zero-maintenance for the life of the unit.

A well-built garden room typically adds 5–15% to property value, depending on location and specification. NOOK Base offers additional investment protection because the foundation is reversible — if you sell, the unit can be taken with you or negotiated as an asset, not a permanent fixture. Property listings that mention a garden office have grown 1,046% over the last decade — buyers now expect it.

Yes — this is one of NOOK's key advantages. Because the foundation is a set of helical-pile screws (not a concrete slab), the entire unit can be detached, craned out, transported and reinstalled at a new location in the same way it was originally delivered. Think of it as a recoverable CAPEX asset rather than a permanent extension.

Every NOOK Base includes a 3-year full warranty covering the structure, steel frame, cladding, glazing, EPDM roof and factory-installed components. All materials are premium-grade with long-term manufacturer guarantees (EPDM membrane, PVC windows, Millboard cladding). We've engineered the unit for 25+ years of durability.
