The rationale behind the design of this striking house was born from the client’s much loved vineyard. The straight lines and repetition of the vines are echoed in the organisation of the interior spaces and precision of the external treatment. The site is overlooked by a listed 16th century church and Ham Hill, a scheduled monument, and as such the roof is covered in wild flower and sedum and runs into the ground reinforcing the house’s connection to its surroundings. The external walls are made of hempcrete and clad in Ham stone and larch. Mill Green far exceeds Passiv-Haus standards, with environmental credentials including a biomass boiler, mechanical heat recovery, solar thermal panels and a PV array.
