Modest in scale, yet big in its effect, this beautifully executed mansard roof extension delivers a spacious master bedroom with a large walk-in dressing area and en suite bathroom. The layout is fully open-plan without doors. A bespoke wall clad in copper designed for the en suite screens off the shower and toilet areas from the dressing zone. The copper wall seamlessly connects with the countertop on which his and hers marble basins sit.
