Challenge

Our clients needed more space for their growing family, so wanted to reintegrate their separate guest residence back into their primary home. To do this, they needed to pursue a lower ground floor and ground floor extension, as well as a mansard roof extension, all in a conservation area with strict design regulations and the potential for objections from the neighbours.

Approach

We sought pre-application advice from the council to tailor our design to what they would be most likely to approve, and also consulted the character profile and guidelines to ensure sensitivity to the conservation area's context. Importantly, we also incorporated a 1.7m privacy screen and adhered to the 45-degree rule to address neighbours' privacy concerns.

Solution

We successfully designed a mansard extension, adding two master bedrooms and an additional bathroom. Plus, we increased the ridge height by 430mm. We also added a modern rear extension to the lower ground and ground floor. This maximised the property's potential, creating a spacious family home that aligns beautifully with the streetscape.

Before & After
