Choices to weigh up in Solihull

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.

Full conversion to a living room or study

The whole garage becomes one room: the door opening is bricked up with a matching window, the floor is raised to meet the house, and walls and ceiling are insulated and plastered. A new doorway from the hall or kitchen usually replaces the old side door, so the room feels like part of the house rather than an add-on.

Your questions answered

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.

Do you cover the whole of Solihull?

Yes — we cover Solihull from our West Bromwich base, including Birmingham, Warwickshire and Sandwell. Call 0800 088 6248 or send the form on this page to book a free survey.

Is a garage floor warm enough for a living room?

Not as it stands. Garage floors are usually bare concrete, lower than the house and uninsulated. We lay a damp-proof membrane and insulation, then a screed or timber floor, so the new room sits level with the house and meets current energy standards. Building control inspects the build-up before it's covered, so you know the floor won't feel cold or damp.

Does Solihull Council need to approve my garage conversion?

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