A clear breakdown of what drives the price of a garden room — size, cladding, glazing and finish — and exactly what's included in a fixed Vita Modular quote. Prices from £19,950, fully installed.
The short answer. A Vita Modular garden room costs from £19,950 inc. VAT, fully installed — a genuinely all-in price covering foundations, the engineered timber frame, full insulation, cladding, glazing, electrics, lighting, heating and flooring. Mid-size studios and gyms are typically £24,950–£29,950; larger and premium bespoke rooms more. Installed in around 7 days, with a 10-year structural warranty.
The honest answer is that "garden room" covers everything from a glorified shed to a fully insulated, year-round building — and the price gap between them is enormous. A Vita Modular garden room is the latter: a permanent, insulated room built to new-build thermal standards, at a fixed, all-inclusive price. Here's what that costs by size.
| Size | Price (inc. VAT) | Typical use |
|---|---|---|
| 3m × 3m (9m²) | £19,950 | Single-person home office, snug studio |
| 4m × 3m (12m²) | £24,950 | Office with meeting space, compact gym |
| 5m × 3m (15m²) | £29,950 | Office with breakout, studio with storage |
| Bespoke | Price on application | Any size, shape or configuration |
Every room is 100% bespoke — the sizes above are common starting points, not a fixed catalogue. A brick-built (masonry brick-slip) finish is a premium option at around a 15% uplift, from approximately £22,950. See our brick garden room guide for that finish.
It's a true turnkey figure — no provisional sums, no mid-build surprises. Quoted separately only where a project needs them: demolition, extensive ground preparation, mains service connections, drainage, optional plumbing and any statutory approvals.
Four things mainly determine where your project lands: size (the biggest factor), glazing (bi-fold and full-height glazing add cost), cladding (brick slip and premium finishes carry an uplift), and internal specification (a home office needs less than a room with a shower or kitchenette). Because every room is bespoke, your written fixed-price quote sets out the exact figure for your choices.
Against renting a desk (£250–£400 a month with nothing owned at the end) or a full extension (£40,000+ and months on site), a one-off garden room from £19,950 usually pays for itself in convenience, saved commuting and added property value — industry estimates suggest a quality garden room can add up to around 10% to a home's value. It's a permanent asset, not a monthly cost.
