Garden Rooms in Tewkesbury — FAQs
Costs, planning, timescales and coverage across Tewkesbury and the West Midlands.
How much does a garden room cost in Tewkesbury?
Our fully-fitted garden rooms in Tewkesbury 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 Tewkesbury and the wider Gloucestershire.
Do I need planning permission for a garden room in Tewkesbury?
Most garden rooms in Tewkesbury 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 Tewkesbury City Council or your local authority.
How long does it take to build a garden room in Tewkesbury?
Once your design is signed off and the base is ready, installation in Tewkesbury 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 Tewkesbury do you cover?
We cover the whole of Tewkesbury and Gloucestershire, including Tewkesbury Town, Ashchurch, Northway, Bredon, Twyning, Kemerton and surrounding villages. Our workshop is 35 minutes from Tewkesbury, 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 Tewkesbury builds stay warm in winter and cool in summer, and come with a 10-year structural guarantee.
