Garden Rooms in Warwick — FAQs
Costs, planning, timescales and coverage across Warwick and the West Midlands.
How much does a garden room cost in Warwick?
Our fully-fitted garden rooms in Warwick start from £9,000 inc. VAT and typically range from £18,000–£35,000 depending on size, cladding and interior finish. Every quote is fixed price and includes insulation, electrics, lighting, flooring, doors and windows — no hidden extras. We provide a free site visit and written quote within 48 hours across Warwick and the wider Warwickshire.
Do I need planning permission for a garden room in Warwick?
Most garden rooms in Warwick fall under Permitted Development and do not require planning permission, provided the building is single-storey, under 2.5m high (within 2m of a boundary) and used as ancillary space — not as a separate dwelling. We handle the full planning check during your site visit and, if approval is needed, prepare and submit the application on your behalf to Warwick City Council or your local authority.
How long does it take to build a garden room in Warwick?
Once your design is signed off and the base is ready, installation in Warwick typically takes 3-5 days. From first enquiry to a finished, plugged-in garden room is usually 6–10 weeks — including design, manufacture in our Tipton workshop and on-site assembly by our own employed team (no subcontractors).
Which areas of Warwick do you cover?
We cover the whole of Warwick and Warwickshire, including Warwick Town, Leamington Spa, Kenilworth, Whitnash, Bishops Tachbrook, Cubbington and surrounding villages. Our workshop is 40 minutes from Warwick, so we offer free same-week site visits with no travel charges within the West Midlands.
Are LouMil garden rooms suitable for year-round use?
Yes — every LouMil garden room is fully insulated to current UK building standards with 100mm PIR insulation in floors, walls and roof, double-glazed thermally-broken doors and windows, and a fitted electric heater. Our Warwick builds stay warm in winter and cool in summer, and come with a 10-year structural guarantee.
