Extend is a design-and-build company based in Fulham, South-West London, that covers the whole London area. We specialise in loft conversions, kitchen extensions and basements, as well as high-end home refurbishments.

All of the projects we undertake are personally overseen by our Managing Director and qualified engineer James Quinn, and we offer a full ’end-to-end' service. James has been working in the construction industry since 2002 and has supervised over 1000 domestic projects.

We take pride in consistently delivering great quality developments on time and on budget. Once we have agreed to work with a client on an expansion or renovation, we are happy to attend to the initial planning, structural calculations and building control submission for the project. On a number of projects, we have also worked as the main contractor, in collaboration with top architects and interior designers who are experienced in luxury home transformations.

There is not sub-contracting at Extend and all of our contracts are made directly with the client. For your peace of mind, our work is guaranteed for a 10 year period.

Loft Conversions:

If you’re looking to transform your old loft space into a new bedroom, playroom or home office, Extend can do it. We have completed a range of loft conversions including dormers, mansards, pod rooms and hip-to-gable loft conversions. Most lofts (if they are not in a conservation area) can be completed under permitted development. To discuss further, we can visit your property to offer a free consultation on your planning requirements.

Kitchen Extensions:

Whether you want to create a larger kitchen/dining area, or increase the square footage of your property and re-design the layout, a ground floor extension from Extend could be the solution. A lot of our clients say that their kitchen extension creates a new central family area in the home, particularly with an open-plan layout. Planning permission is required for many side-return kitchen extensions but the majority of local authorities approve these under certain conditions. Some types of extension can be completed under permitted development or the neighbourhood consultation scheme. Get in touch and we can visit your property and offer a free consultation on your planning requirements.

Basement Conversions:

A great way to add space to your home is to create a retro-fit basement under your existing property. Basements are a large engineering project and Extend can provide an engineer to oversee the process for the duration of the project. All basement conversions require planning permission. Extend are experienced in dealing with the many requirements that the local authorities require to grant permission. We can also advise on the Party Wall requirements of a basement and also ensure that we are considerate contractors during the build phase. A basement is a great way in adding a large amount of square footage to your property without dramatically changing the visual appearance. A wide range of rooms can be installed from cinema rooms to the humble utility room!
