Hilldrop Road

This project was for a 5th floor roof extension to a four storey early Victorian semi-detached town house in an Islington Conservation Area.

The Conservation Area rules were very restrictive (no construction to be visible to the front above the parapet). The height of the project also imposed technical challenges with regard to compliance with the fire and building regulations.

We developed a lightweight timber frame in conjunction with the engineer that





worked with the existing proportions of the structure and could be constructed above the existing flat whilst the clients remained in the property. The stepped section maximises the available headroom, and the design includes a self cleaning glass slot wrapping over the roof, pre weathered zinc cladding, a walk in wet room and high quality Schüco sliding doors.

The result is a flexible south-east facing extension and roof terrace with fantastic views over London.
