Services
Loft Conversions
We specialise in converting underutilised loft spaces into functional living areas while maintaining structural integrity. Our conversions maximise headroom and incorporate necessary insulation, flooring, and ventilation. Clients benefit from increased property value and additional living space without planning permission requirements in most cases.
House Extensions
Our house extensions create additional living space tailored to family needs, including kitchens, bathrooms, and multi-functional rooms. We handle planning permissions, structural calculations, and material sourcing while ensuring seamless integration with existing property aesthetics.
Home Refurbishment
We deliver comprehensive property upgrades from kitchens and bathrooms to full structural renovations. Our process includes modernisation of utilities, space optimisation, and design enhancements that improve functionality while maintaining architectural character in both period and modern properties.
New Builds
We construct bespoke residential properties to modern energy-efficient standards. Our new builds incorporate smart home technology, open-plan living spaces, and tailored design elements while managing all regulatory approvals and construction phases from foundation to completion.
Garage Conversions
We transform existing garage spaces into functional living areas that complement property requirements. Our conversions maintain structural integrity while integrating insulation, electrical systems, and finishing touches that match the main property's aesthetic and functionality.

Matt and his team built a rear ground floor extension for us in Islington. The price was competitive, Matt was quick to reply to any questions and helpful with suggestions and ideas. The quality of the work is excellent, Claud and Wojtek are highly skilled builders and we are very happy with the finish. Matt also coordinated well with other trades that were involved and the project progressed as expected. We had some minor delays as there were some complications with the piled foundations but Matt managed this well and minimised the impact on our project. I would highly recommend Firtree to anyone

We recently used Firtree Building Services for our downstairs rear extension and were really pleased with the result and have no hesitation in recommending them. The job was completed on time and on budget and the quality of the finished work was excellent. We found the entire team to be very reliable and hardworking and they minimised disruption so we were able to work from home throughout the entire build. The Project was well managed and Matt was happy to give advice and suggest options at different stages. Thanks very much to Matt, Joe, Dan and Sean for all the hard work!

Useless. Came to see us in July to get a quote- measured up our house and said the quote would take two weeks to do- no idea why it would take so long. 3 weeks later, when we still hadn't heard anything, I texted the owner and asked for an update and was told the quote was on its way. It's now October and no quote received, no contact, no explanation. Lazy and poor customer service. Avoid.

We used Fir Tree to convert our loft and found them to be polite, tidy and never left a mess. Would wholly recommend.
