How much does a garage conversion cost in Teesside?

A typical full garage conversion in Teesside costs £10,000 to £18,000 in 2026, making it the cheapest way to add a proper room to most houses. A part conversion, keeping the front of the garage for storage and converting the back, runs £6,000 to £12,000. At the top end, a double garage or a conversion with an en-suite or kitchen fits out at £15,000 to £25,000, and detached garages £15,000 to £30,000 depending on services.

What moves the price most is not the size but the specification: the floor build-up and damp proofing, whether you are adding a bathroom or kitchen, and how the old garage door opening is closed up. Every quote here is priced off a proper look at your garage, which is the only way a conversion quote means anything.

Full breakdowns, including floors, damp proofing, utilities and the extras that move quotes, are in our Teesside garage conversion cost guide.

Teesside's most underused rooms

Most integral garages on Teesside hold a freezer, some paint tins and everything that has nowhere else to go, while the house next door needs another bedroom, an office or a kitchen the family can actually sit in. Converting the garage typically adds 15 to 20 square metres of proper living space for roughly a third of the cost of an extension, with no loss of garden and no new foundations.

The local stock suits it. The 1930s semis of Acklam, Hartburn and Fairfield, the post-war estates across Billingham and Thornaby, and the newer detached houses of Wynyard and Ingleby Barwick almost all carry integral or attached garages that were designed as part of the house, which makes the structural side straightforward. One honest caveat: garages on some new-build estates sit under developer covenants that restrict conversion, and a good quote will flag that before you spend anything.

What good looks like

Every quote follows the same standard, and it is the same four things worth asking for whoever you choose:

• Insured: public liability cover, shown on request.
• Proven: finished garage conversions locally you can go and look at.
• Written quotes: itemised, with the floor build-up, insulation, electrics, plastering and building control fees specified, never a single line and a cash price.
• Certified: building regulations sign-off arranged as part of the job, with the completion certificate handed over at the end.

Planning permission, usually not needed

Most garage conversions need no planning application at all: you are altering the inside of an existing building, not extending it, so the work normally falls outside planning. Building regulations approval is different and always applies, covering the floor, damp proofing, insulation, ventilation, electrics and fire safety. Our planning and building regs guide explains exactly where the lines sit, and the ideas guide helps you work out which conversion your garage suits.
