Challenge

Our clients were a young couple who were letting out their terrace house but wanted eventually to use it as their family home. The home they dreamt of would have a spacious master bedroom with an en-suite bathroom. On the ground floor, there would be a large living-dining area with lots of natural light opening out onto the garden, plus the option of a ground-floor bedroom.

Adding that much space to the house would require a two-storey creative house extension. The challenge was that there was no precedent for building an extension on this scale in the terrace that the house forms a part of. What’s more, the first-floor extension could potentially block daylight for the neighbours. These issues meant that obtaining planning permission could have been tricky, and required a creative approach to designing the extension.

Solution

By using angled walls for the extension on the first floor, we were able to comply with the 45-degree rule local planning authorities use to ensure that neighbours do not lose their access to daylight and sunlight. But rather than treat those angled walls as a merely practical solution to a technical problem, we mirrored them on the ground floor, using them to give the design of the house a bold new dynamism.

When designing the scheme, we took an imaginative approach that took advantage of the layout of the creative house extension so that it transitions well into the garden space. With meticulous attention to detail, we considered all the specifics that produce an integrated scheme. By doing this, our creative house extension design approach fulfilled our clients’ wish for a house that was much more exciting than it had been before, at the same time as both storeys of the extension provided a huge increase in living space.
