Challenge

Our task was to design a small extension that would add space without squandering the property’s historical charm. The existing layout was impractical, the only bathroom located two floors below the main bedroom. Considering its location in a strict conservation area, it was important we approached the design with sensitivity.

Approach

Understanding the constraints of the conservation area, we proposed a subtle single-storey extension that would sit atop the existing lower-ground floor extension. To neatly blend the new extension with the existing home, we opted for a modern zinc shell and used timber slats for added privacy.

Solution

The final design featured a modest yet impactful extension and added a new light-filled bathroom to the home. The addition also included a green roof to enhance the garden connection. Ultimately, this small but significant change greatly improved the house's functionality while preserving its Victorian beauty, demonstrating the value of thoughtful, sensitive architectural solutions.
