Which option fits your home?

Detached garage conversion

A separate garage can become a home office, gym or garden room. It usually needs more work than an integral garage, with new insulation throughout, a power supply run from the house and often a new roof covering. If it's to be lived in as a separate bedroom or annexe, planning permission is likely to be needed.

Ground-floor bedroom with shower room

Useful for an older parent, a teenager or visiting family. A shower room at the back of the garage needs a waste connection, so the route to the nearest drain is checked first. If gravity drainage isn't possible, a pumped system may be allowed, provided the house also has a toilet that drains normally.

What does your garage conversion cost in Selly Oak?

Guide prices start at £7,500 and run to £40,000 depending on size and specification. A single integral garage converted into a study or playroom: around £13,500–£18,000.

Questions about garage conversions in Selly Oak

Will converting the garage affect parking or the value of my house?

You'll lose the garage as parking, so it's worth checking that the driveway is big enough and whether any planning condition requires the garage to stay available for a car. Whether the conversion adds value depends on your street; in many areas an extra room is worth more than a garage, but a local estate agent is the best judge for your home.

How long does a garage conversion take?

A straightforward single garage usually takes 3–5 weeks on site. Allow a few weeks beforehand for drawings and the Building Regulations application, and longer if a planning application is needed. Window and door lead times can affect the start date, so we order them as soon as the quote is accepted and the drawings are agreed.

Who approves garage conversions in Selly Oak?

Not usually for planning, unless a condition on your estate removes permitted development rights — Birmingham City Council can confirm. Building Regulations approval is always needed for a garage conversion.
