Conversion of a set of ancillary buildings into a five-bedroom contemporary house

The original ancillary buildings adjacent De Montalt Mill consisted of four adjoined elements of varying heights - two barns, one furniture-maker's workshop and one 'farm-use' building. This conversion knits together the refurbished spaces with a ribbon-like circulation route, which undulates around the dominant central Bath stone wall.

The house is entered from the north courtyard into a stone double-height space, crossed by a bridge at first floor level. Through a tight slot in the main spine wall, stepping onto the raised circulation ribbon, you enter a daylit open-plan living space with a view of the valley.

The private bedroom and bathroom spaces are arranged across two floors on the north side, divided by the double-height entrance hall, bridged by the ribbon.

The new roof structure of the lean-to connects at high level to the Bath stone spine wall. At the junction between these two elements, a continuous rooflight draws sunlight down the wall face illuminating the space below.
