Garage Conversion
Frequently Asked Questions
We hope this page provides clear and helpful answers for those considering a loft conversion who may have numerous questions about the process; we are here to make your decision as straightforward and informed as possible.
1
How much value does a garage conversion add to my home?
A garage conversion typically adds £20,000–£50,000+ to your home's value in the UK (often 70–90% of the conversion cost), depending on quality, location, and whether it creates an extra bedroom or ensuite.
2
Can my garage be converted?
Your garage can likely be converted into habitable space, provided it meets UK building regulations (mandatory for conversions) and has a minimum head height of around 2.2–2.4 metres (after insulation and flooring adjustments, with 2.2m often the practical benchmark)—if below this, you can raise the roof to increase height, but that typically requires planning permission. Most internal garage conversions don’t need planning permission unless in a conservation area or restricted locally—check with your local council first.
3
How much does a garage conversion cost in Sussex?
In Sussex, a garage conversion typically costs £12,000–£25,000+ in 2026, with averages around £15,000–£20,000 for a standard single garage—though this can vary significantly based on size, specifications, garage type (integral, attached, or detached), finishes, and extras like plumbing or electrics.
4
How long does a garage conversion take ?
A standard garage conversion takes 3–6 weeks, though this can vary from 2–4 weeks for basic projects up to longer for more complex conversions, depending on size, specifications, and any extras like plumbing or structural changes.
5
Do I need planning permission for a garage conversion?
You usually don’t need planning permission for a standard internal garage conversion in Worthing, as it’s often considered permitted development—however, you must comply with UK building regulations, and planning permission may be required if you’re in a conservation area, listed building, raising the roof, or making external alterations—always check with your local coucil first.
6
Can I add an ensuite bathroom to my garage conversion?
You can add an ensuite bathroom to your garage conversion, but it’s more tricky (and often more expensive) than in loft conversions because garages are on the ground floor, so groundwork like new drainage, sewage connections, and possibly a sump pump or raised floor will usually need to be done.
7
What can I turn my garage into?
A garage conversion can become a variety of functional spaces, such as an extra bedroom, home office, gym, playroom, utility room, annexe, or even a kitchen extension—popular choices depend on your needs and the garage's size/layout.
