Extension & Alteration to a Georgian Grade II Listed Home in St Leonard’s Conservation Area
We were appointed to transform a tired, outdated sunroom at Manston Terrace into a striking, light-filled contemporary extension. The new addition features slim-framed aluminium doors and a dramatic wide roof-light, flooding the space with natural light and creating a seamless connection to the garden. Inside, a section of glass flooring was introduced to channel daylight into the basement below—now repurposed as a sleek home gym.
A bespoke kitchen was installed in the original dining room, blending modern functionality with heritage sensitivity. While kitchen installations typically fall outside the scope of Listed Building Consent, this project involved a new floor finish and underfloor heating. We therefore included it in our submission to the Local Authority, ensuring transparency and demonstrating our commitment to preserving the building’s historic features. Original architraves and skirtings were carefully retained and protected throughout the works.
With an RIBA Conservation Architect on our team, we produce detailed Heritage Statements to support our applications. These documents are essential in Conservation Areas and when working with Listed Buildings, as they show a thorough understanding of the building’s significance and guide sensitive design decisions. This proactive approach helps streamline the consent process and fosters constructive dialogue with Conservation Officers.
New Rear Extension
These photos show the existing conservatory which was demolished and replaced with the proposed contemporary flat roof extension (shown to the right).
Quite a transformation!
Side Garage Extension

The proposal located an internal garage, utility and wc with access through to the garden and kitchen extension. The front elevation of the house remain the same with the new flat roof tying into the existing wall.
Existing Stairs
The existing staircase down to the basement gym were removed to allow for more floor space in both the gym and extension.
To draw light into the basement a glass floor is installed underneath a flush rooflight.
