From extensions and loft conversions to kitchen extensions and full refurbishments, Firtree Build is a local Enfield building company that manages the whole project.
Project managers, structural engineers and skilled trades work as one team, so you deal with one point of contact from consultation to completion.
What we build
Whether you are expanding a growing family home, modernising an older property or planning a full renovation, the right local builder makes all the difference. Enfield’s mix of Victorian terraces near Enfield Town and 1930s family houses in Winchmore Hill and Southgate each present their own structural considerations, which is where local, hands on experience counts.
Rear and side return
Rear and side return extensions to expand kitchens and living areas, managed from structural preparation through to final finishes.
Dormer and rooflight
Dormer, rooflight and en suite loft conversions that turn unused roof space into an extra bedroom, office or bathroom.
Garden and side return
Open plan kitchen diners built into garden or side return space, bringing more light and space into the ground floor.
Whole property
Structural alterations, layout modernisation, and kitchen and bathroom updates for a full property refresh.
Ground up
New residential builds across North London, managed from initial design through to completion and certification.
Not sure which?
A rear extension solves a different problem from a loft conversion. Our guide explains which fits your Enfield home.
Local knowledge, not a generic template
Enfield is one of North London’s most established residential areas, with neighbourhoods including Enfield Town, Winchmore Hill, Southgate, Palmers Green, Edmonton and Bush Hill Park. Many homes here were built in the Victorian and early twentieth century periods, with character and charm, but not always designed for modern living.

Builders Enfield FAQs
It depends on the type and scale of the project, the structural work involved, materials and design. We provide a detailed, itemised quote after a site visit rather than a single headline figure.
Many home improvements fall under permitted development rights, so planning permission may not be required. This depends on the size of the work, the type of property and whether it is in a conservation area. Larger extensions usually need planning approval from Enfield Council.
We provide house extensions, loft conversions, kitchen extensions, home refurbishments and new builds, coordinating architects, structural engineers and Building Control inspections so every project meets UK Building Regulations.
It depends on size and complexity, and extra time may be needed for planning approval, design work and structural calculations before construction begins. We give you a realistic timeline in your quote.
