Garage Conversion Specialists in Brighton & Hove

Create a guest suite · Home office · Gym · Playroom — without extending

Turning an under-used garage into a fully insulated living space is the fastest, most cost-effective way to gain 15–25 m² in Brighton & Hove’s high-value property market. Safe Bricks Limited manages every stage—survey, planning, structural tweaks, plumbing, electrics and flawless finishing—so your conversion feels purpose-built, not retro-fitted.

Why Convert Your Garage?

Cost-effective floor area – far less than a full extension.
No garden sacrifice – keep outdoor space untouched.
Often no planning permission – most single garages fall under Permitted Development (check height changes & conservation status).
Boost EPC & value – we add cavity insulation, breathable renders or mineral-wool EWI for warmer, greener living.
Perfect for WFH – create a quiet office with wired data, sound insulation and plenty of daylight.

Frequently Asked Questions

Do I need planning permission?
Most garage conversions are internal works under Permitted Development. You will need consent if you alter the roof height, change the façade in a conservation area, or live in a listed building.

How long does a conversion take?
A straightforward single garage averages 4–6 weeks; extras like bathrooms or complex drainage add 1–2 weeks.

Will it be warm enough to live in?
Yes—our insulation levels meet or exceed Part L 2025. Breathable lime or silicone renders stop condensation.
