Why Choose Fixiz for Your Garage Conversion?
Choosing the right builder for your garage conversion is one of the most important decisions you’ll make. At Fixiz Ltd, we bring years of specialist experience in residential conversions across North London. Every project we undertake is managed from start to finish by our dedicated team, ensuring quality craftsmanship and full compliance with Building Regulations. We understand that a garage conversion is a significant investment in your home. That’s why we provide transparent, fixed-price quotes with no hidden costs. Our process begins with a free site survey where we assess your garage, discuss your vision, and provide honest advice about what’s achievable within your budget. Unlike many builders who subcontract work, our in-house team handles every aspect of your conversion including structural work, insulation, plastering, electrics, plumbing, and final decoration. This means better quality control, clearer communication, and a smoother experience for you as a homeowner.
How Much Value Does a Garage Conversion Add to Your Home?
A well-executed garage conversion is one of the best returns on investment you can make as a homeowner. A quality garage conversion in London can add between 10% and 20% to your property value. For an average North London home valued at £500,000, that could mean an increase of £50,000 to £100,000 in property value from an investment of just £12,000 to £25,000. The key to maximising value is ensuring the conversion is completed to a high standard with proper Building Regulations sign-off. A completion certificate from Building Control is essential when you come to sell, as buyers and mortgage lenders will require evidence that the work was carried out legally. Fixiz handles all Building Regulations applications and inspections as part of our service.

Garage Conversion FAQs
Quick answers to the most common questions.
Do I need planning permission for a garage conversion?
Most garage conversions fall under Permitted Development and do not require planning permission, provided the work is internal and the garage is attached to the house. However, all conversions require Building Regulations approval — Fixiz handles all applications and inspections on your behalf.
Will a garage conversion add value to my property?
Yes. A professionally completed garage conversion can add between 10% and 20% to your property value. Having a Building Regulations completion certificate is essential for this added value to be recognised by estate agents and mortgage lenders.
How do you handle the garage floor step-down?
Garage floors are typically 100–150mm lower than the rest of the house. We install a damp-proof membrane, rigid insulation boards, and either a screed or timber floor to bring it up to the correct level — this is standard on every Fixiz conversion.
How long does a garage conversion take?
A standard single garage conversion typically takes 2–3 weeks from the start of construction. The full process including survey, design, Building Regulations, and construction usually spans 4–6 weeks. We provide a clear timeline during your free survey.
What happens to the garage door?
The garage door opening is bricked up and a new window or French doors are installed, matched to the existing house exterior. Some homeowners choose bi-fold doors to maintain a connection to the driveway or garden.
