Looking for a Professional London Garage Conversion? Look No Further
1. Proficiency

At the forefront of London's garage renovation scene, Proficiency a building company who stands out with many years experience in overseeing the whole process, from planning applications to structural building work. Handling every aspect of property renovations, from house extensions to bespoke new build properties, Proficiency's expert team of hardworking designers and architects operate from the heart of London to oversee the entire project, with the highest quality showroom and studio to spark your design ideas.
What sets Proficiency apart is an impressive portfolio of successful architectural services, ranging from structural calculations and planning permission to fully-managed house refurbishments, including new bathrooms, family rooms, dining rooms, office spaces, games rooms and property extensions, including one project that earned the coveted front cover of KKB magazine in October 2018.

The innovative use of 3D garage conversion software, alongside expert advice, allows clients to visualise all aspects of the garage conversion process with razor-sharp precision and accuracy.

2. Essex Garage Conversions
Essex Garage Conversions - with over 30 years in the game - offers a diverse range of home improvement services beyond just garage conversion services to improve the value of your home. With a portfolio including driveways, kitchens, and porches, they are a worthwhile consideration if you're trying to add extra space in a cost-effective way.
Offering a 10-year guarantee on their garage conversion projects, this also includes cover for electrical work. While Essex Garage Conversions are, by name and location, not directly local to London, they have espoused their ability to offer competitive garage conversion costs. That said, their average ratings and testimonials - while impressive - aren't as detailed as others on this list.
If you're based in a local authority outside of Central London boroughs (apart from perhaps West and North West London), you may fare better with this local firm.
3. CDC Garage Doors

With over 15 years of specialist garage conversion experience, CDC Garage Doors has established itself as a trusted name in the South East. Based in East Sussex, they do cover local councils in and around Greater London, purely specialising in garage doors. They offer a variety of professional GRP garage doors, timber doors and doors with new windows, together with fully automated and electrical door systems. All are manufactured in UK factories under strict quality control, with full Building Regulations Approval, and an unwavering commitment to quality materials.
They are therefore very well placed to work with dual purpose conversions where a level of garage space will be maintained and external finishes need to be considered. CDC Garage Doors commitment to customer service and professionalism is illustrated by their nothing under 5-star ratings as a company across 27 reviews. However, further reputable trades would need to be explored for any interior design or additional work when fully converting garages to extra bedrooms, home offices or other habitable rooms.
4. First Choice Conversions
First Choice Conversions brings more than 15 years of garage conversion project experience to the table, specialising in overhauling the most basic of existing structures into luxury and functional living spaces. Boasting approval and full development rights, they too are Essex-based but do serve London boroughs offering versatile conversion choices such as home offices, TV rooms, sports studios and even home bars. Their proven track record demonstrates their innate ability to adapt complex and unused spaces into value-adding rooms that thoroughly complement London homeowners' quality of life.
With a wide range of case studies extending far beyond garage conversions, to include other areas of the home such as bathroom conversions, First Choice Conversions have established themselves in all areas of renovation and design. Their aggregated full 5-star ratings on Google (based on 23 reviews at present) are also hard to overlook, which all but confirms they have an astute positive reputation as a building company.
5. Equus Design and Build

Equus Design and Build takes a modern approach to garage conversion projects, utilising computer-generated imaging and project management software to help clients visualise all of their potential outcomes. Their technology-forward approach to renovations allows homeowners to explore different design options and decide on any change of use before committing to the final outcome.
They have provided a range of automotive garage builds and conversion projects, not just in the domestic sector but in the commercial sector as well. One such case study is the impressive Tudor Coach House garage showroom. Equus Design and Build’s 5-star average rating further lends credibility their way, as does their impressive portfolio. However, they are based further afield (Wantage) meaning that their proximity to London is not as close as the others on this list.
Conclusion: Where to Go for a London Garage Conversion?
While each of these garage conversion specialists brings an array of strengths, qualities and services, Proficiency emerges as the most compelling and worthwhile consideration for London homeowners. Local expertise, comprehensive in-house architectural services, and proven track record of high-end projects sets Proficiency apart for homeowners seeking a professional garage conversion.
However, that doesn't mean that any of the others should be ignored. CDC Garage Doors are unmatched in terms of their garage door installations, while Equus Design and Build's innovative garage visualisation software, commercial experience and tech-led approach are, frankly, outstanding. First Choice Conversions' versatility and Essex Garage Conversions' diverse home improvement portfolio solidify them as excellent in their field, particularly for homeowners in Essex and the surrounding area.
That said, for London homeowners seeking a garage conversion expert, Proficiency’s customer satisfaction and diverse service offerings speak volumes, not to mention 3D visualisations and a full project management experience. We firmly believe Proficiency are best placed for those seeking a high-quality garage conversion in London. But if you are to take anything at all away from this guide, we recommend evaluating each potential garage conversion company in fine detail, considering your budget and specific project requirements to find the best match for your immediate and future needs.
