A picture framer and a designer for performance left London for the banks of the River Test, where a 17th-century water mill had spent decades as an unloved rental. We refurbished the Grade II listed mill house and added a new studio and workshop, giving each of their practices a dedicated home on a Site of Special Scientific Interest, immersed in the river, its Mill Run and settling ponds.

In the house, we stripped back later modifications to reinstate the original plan and open up the living spaces. Working throughout with Hampshire's conservation officers and the SPAB, we reinstated the hand-crafted character of the house with natural materials: wood fibre insulation, lime plaster, and linseed on the lath-and-plaster walls. Enabling works uncovered a bread oven behind a brick wall, which we retained; the kitchen around it is fitted out with self-made joinery. A ground floor extension wraps one corner to create an open-plan dining and sitting room, and a water source heat pump draws from the mill race in place of fossil fuel heating.

The studio annexe is a single-storey timber structure, clad in locally sourced heat-treated sycamore that will weather into the trees at the boundary. We planned each studio around its practice: a north clerestory brings glare-free light to the woodworking workshop, and a south oculus marks the relationship back to the house.
