AD++ House

A two-storey extension in a conservation area in York that includes a glazed and elevated living space to enjoy the evening sun

The project includes a large, elevated living space heavily glazed to the west, to enjoy the evening sun, with a red stair leading to the studio at ground level.

The family who live in the home have a long tradition of working in the seed trading business. Our extension connects the home to the adjoining landscape and offers a place for planting. An external water features create a sense of place and relaxation. The roof cantilevers a significant distance to cut and carve the consistent pitched roof form to allow light and views to and from the space. As the sun tracks around in the afternoon the space is filled with light and the shadows of the leaves from the surrounding trees.

A SUSTAINABLE SOLUTION

The project is constructed primarily from sustainably sourced timber and clad in recycled zinc. Zinc uses the least amount of ores out of all non-ferrous metal cladding solution – 1/4 that of aluminium and 1/2 that of copper and steel. Additionally, zinc requires low levels of maintenance during its life cycle and is a self finish material that ages with beauty, omitting the need for continuous redecoration.

“Thanks to Coffey Architects, we have added a striking, modern addition onto a house. We have enjoyed working with them, and winning two RIBA awards is one hell of a bonus!”

LIGHT AND SHADOWS

The pitched roof is cut and folded to create a tension between the cantilever and glazing, allowing south sunlight to penetrate deep into the house. The self-finish zinc cladding both reflects and contrasts with the surrounding trees.

A CONNECTION

The addition extends the existing living area at first floor; glazing visually connects it to the landscape beyond an adjacent retaining wall. This new living space is linked to a studio/guest room below, via a 1m2 bold red stair.
