Grafton House, 24 Mount Street

This project involved a contemporary extension and basement conversion to a period property in a Conservation area, the property itself was not listed but was of high Architectural merit.

We initially approached the Local Authority to agree a design philosophy which concluded in us proposing a modern glazed structure to minimise the impact on the symmetry of the existing property.

The design used an internal steel frame but ensured that the two end gables were self supporting in order that the view through the structure was uninterrupted.

The basement to the property was converted at the same time and the excess heat produced by the basement space was used to warm the glazed structure during the winter.

The glass structure was designed under existing trees which provided shelter from the sun during the summer months.
