Frequently Asked Questions

Common questions about garage conversions in Surrey.

Do I need planning permission for a garage conversion?

In most cases, converting an existing garage does not require planning permission as it is classed as a change of use within the building envelope. Exceptions include listed buildings, properties in conservation areas, or where the conversion changes the external appearance significantly. Building regulations approval is always required.

Will a garage conversion add value to my home?

Yes, a high-quality garage conversion typically adds 10–15% to the property value and is one of the most cost-effective ways to gain extra square footage. Converting a double garage into a home office or additional living room is particularly popular in Surrey.

How long does a garage conversion take?

A standard single-garage conversion takes around 3–5 weeks from start to handover. Double garages or conversions with en-suite bathrooms or complex layouts may take 6–8 weeks. We will confirm the timeline in your quote.

Can the garage door be retained while converting the interior?

Yes, in some cases homeowners prefer to retain the garage door for visual continuity, particularly on the street frontage. We can insulate and line behind the door and create a full internal room while keeping the external appearance unchanged.

What can a converted garage be used for?

Popular uses include home offices, playrooms, gyms, guest bedrooms, cinema rooms, and utility or boot rooms. We design the conversion around how you want to use the space, ensuring appropriate insulation, lighting, and heating are included.
