NOOK quality
Permanent-building materials and architect-designed lines. The solidity of a house — a steel frame, 50 mm sandwich panels, an A energy rating — placed in your garden in a single day.
Materials
Every layer chosen to last decades and hold its temperature year-round. This is what sits beneath the finish.
The thermal envelope
It starts with a reinforced steel frame. Around it sit 50 mm high-density sandwich panels, rock-wool partitions with improved fire resistance, and a double-layer false ceiling that cuts thermal bridges. The result? An A energy rating and a steady temperature 365 days a year, whatever the weather does outside.
Carpentry and glazing
High-efficiency PVC exterior carpentry, built for extreme climates. A two-pane sliding window and a sliding door, both with double safety-tempered glazing on both sides. Floor-to-ceiling light comes in; the cold stays out.
Exterior cladding
As standard, Zenwood thermo-treated cladding in Black or Oak, re-lacquered every five years or so. Prefer to never think about maintenance? Millboard composite asks for none and lasts 25+ years. You choose the finish when you configure your NOOK.
Reversible foundation
Your NOOK rests on screw-in helical piles. Half a day to install, no civil works, no concrete. They lift out or relocate with no mark left on the land — Mobility & Demountability Certificate included. The garden stays yours.
NOOK vs. traditional build
We compare against a professional builder-led extension — not DIY kits.
Indicative comparison. Traditional-build timelines and overruns per industry estimates and internal NOOK models.
Included and extras
Turnkey as standard. Personalise the rest with curated extras — pricing is calculated live in the configurator.
Thermo-treated wood is re-lacquered roughly every five years. If you'd rather skip maintenance entirely, Millboard cladding needs none and lasts 25+ years.
Structural extras (porch, sloped roof, deck) are chosen when you configure your NOOK, before production. Tell us your project in a consultation and we'll plan it with you.
No. Helical piles screw in within half a day — no concrete, no civil works — and can be removed with no permanent mark. They include a Mobility & Demountability Certificate.
A 3-year structural warranty. Every NOOK passes four factory inspections — structure, envelope, services and finishes — before it leaves.
Yes. The envelope combines 50 mm sandwich panels, rock wool, a high-density roof and a double-insulated false ceiling, with an A energy rating for four-season use.
Exterior in Thermo-treated wood (Black or Oak) or Millboard; laminate flooring in Dark, Caova or Sand; optional linen walls and a panoramic window. Everything previews and prices in the configurator.
The NOOK Base (9.75 m²), the NOOK Doble (19.50 m²) and the NOOK Sauna. Modules dock together at the factory, so you can grow to 30–40 m² on a single foundation.
The price is fixed before production — without the +30–40% overrun a traditional build typically runs — and you're ready in 12–16 weeks instead of months. We compare a prefab garden room with a traditional extension here.
