Building your own home is, for many, a dream come true but it can also be a living nightmare if your architect is sloppy or inexperienced. At Extension Architecture, we have decades worth of experience of helping people develop property for profit or creating their forever home across the whole of London, in boroughs such as Redbridge, Haringey, Mole Valley, and Lewisham. We project manage the whole thing, leaving you to relax and enjoy the process.

When you self build you can have your house exactly as you want it and enjoy living somewhere that you created. Hate cooking but love entertaining? A smaller kitchen and larger living room might be hard to find in an existing property but easy to build yourself. Want a separate room to hide the kid’s toys in without sacrificing your dining room? No problem! Sometimes, a plot is perfect but the existing house needs so much work doing to it, it is easier to knock it down and start again.

Alternatively, you might be interested in rebuilding a house on an existing plot, or having a quick, turn key solution to be able to sell on and make a profit.

Whatever your reasons for wanting to build a house from scratch, we can help. Whether that is conducting a site survey or Topography survey, designing the interior and exterior, or project managing the whole thing.

Take a look at the new build case studies below for inspiration, or get in touch to find out more about how we could help you take your home to the next level.

New Build Case Studies

Extension Architecture are experienced in creatively collating ideas and translating your brief(s) into actualisations with our Architectural and Interior Design experience. Through mood boards and 3D realistic renders we are able to provide the client with suggestions and visualisations of the potential space. This can help with planning projects, especially if a challenging proposal to help illustrate to the planners the proposed idea; or for large scale developments and refurbishments to show the client the new proposal and how it would look and fit in situ with surrounding properties and the existing building. We liaise with the client in order to be able to achieve an interior finish of high quality and befitting to the needs and budget.
