Garage Conversion Basingstoke — Garage Conversion Specialists in Basingstoke

Garage Conversion Basingstoke converts garages across Basingstoke and the surrounding towns and villages, and does nothing else. That focus matters because a garage conversion carries the same structural, thermal and regulatory questions as any other habitable room, even though it looks like the smallest project on offer. We survey every garage before quoting and give you a fixed written figure.

Our Garage Conversion Services

Five conversion types, and the right one for your property depends on the garage itself and how you want to use the space.

Single garage conversions convert an integral single garage into a proper room, usually the cheapest way to add genuine space to a Basingstoke house. Most single garages across the town’s estate housing have held nothing but bikes and a chest freezer for years.

Double garage conversions open up a genuinely large amount of space, common on the executive-style properties around Hatch Warren, Brighton Hill and parts of Chineham, either as one open room or split into two.

Home office conversions build in a proper electrical first fix for hybrid working — Basingstoke sits on the Waterloo mainline and has long been a base for commuters who need a genuinely separate space to work from.

Bedroom conversions are built to the escape window and fire door requirements a habitable bedroom needs, and are usually the cheapest way to take a three-bedroom house to four.

Partial garage conversions keep a utility area for the washing machine and bin storage while converting the rest — a good fit for the compact kitchens common on Basingstoke’s older estates.

Why Choose Garage Conversion Basingstoke

• We survey before we quote. Damp checked, wall and roof construction assessed, conservation status confirmed. A quotation without those things is a guess.
• Fixed written quotations. Damp proofing, insulation, Building Regulations submission and making good are inside the figure, not sitting outside it as provisional sums.
• We design bedrooms to fire safety standards from the start, rather than treating escape windows and fire doors as an afterthought.
• We tell you when a partial conversion is the better answer, rather than selling a bigger job than the household needs.
• Approvals handled throughout, including planning and listed building consent in Old Basing and Overton where they apply.

Areas We Serve

We work across Basingstoke and the surrounding towns and villages, and each has its own character worth knowing before you start.

Chineham is later, larger-plot housing with more double garages than the rest of the district. Old Basing sits partly within a conservation area with a real concentration of listed buildings. Tadley grew rapidly after the war around AWE Aldermaston, producing more variable construction than a single planned estate.

Hook was largely built from the 1960s onward around its railway station. Overton is a genuinely old market town where many garages are later detached additions rather than integral.

What a Garage Conversion Costs

Locally a basic single garage room starts around £9,000 and a fully fitted double garage annexe reaches £36,000. Cost is driven mainly by what the room is for — an office, a bedroom, or a room with plumbing — rather than by structure the way a loft conversion is.

Our 2026 cost guide breaks that down by conversion type with worked examples from real Basingstoke properties. The building regulations guide explains what approval actually covers, and the value guide sets out which conversion types add the most to your property.
