Garden Rooms in Halesowen — FAQs
Costs, planning, timescales and coverage across Halesowen and the West Midlands.
How much does a garden room cost in Halesowen?
Our fully-fitted garden rooms in Halesowen 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 Halesowen and the wider West Midlands.
Do I need planning permission for a garden room in Halesowen?
Most garden rooms in Halesowen 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 Halesowen City Council or your local authority.
How long does it take to build a garden room in Halesowen?
Once your design is signed off and the base is ready, installation in Halesowen 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 Halesowen do you cover?
We cover the whole of Halesowen and West Midlands, including Halesowen Town, Quinton, Hayley Green, Cradley Heath, Old Hill, Blackheath and surrounding villages. Our workshop is 25 minutes from Halesowen, 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 Halesowen builds stay warm in winter and cool in summer, and come with a 10-year structural guarantee.
