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

Do I need planning permission for a garage conversion in London?

Most garage conversions fall under Permitted Development rights and do not require planning permission, provided the work is internal, you are not extending beyond the original building footprint, and the garage is attached to the house. However, if your property is in a Conservation Area or is a listed building, you may need to apply. All garage conversions require Building Regulations approval, which Fixiz handles 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. The exact amount depends on factors like the quality of the finish, the type of room created, and the local property market. 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 floor level step-down in a garage?

Garage floors are typically 100-150mm lower than the rest of the house. We address this by laying a new insulated floor to bring it up to the correct level. This involves installing a damp-proof membrane, rigid insulation boards, and then either a screed or timber floor on top. This is a standard part of every Fixiz garage conversion.

How long does a garage conversion take?

A standard single garage conversion typically takes 2 to 3 weeks from the start of construction. The full process including survey, design, Building Regulations submission, and construction usually spans 4 to 6 weeks. We provide a clear timeline during our free survey.

What happens to the garage door during a conversion?

The garage door opening is bricked up and a new window or French doors are installed. The new brickwork is matched to the existing house exterior. Some homeowners choose bi-fold doors to maintain a connection to the driveway or garden.
