PROJECT REPORT: SELFBUILD & CUSTOM BUILD PROJECTS

work of Belgian architect Vincent Van Duysen helped “give a steer on how to get the finer details right,” and the precise framing of the brick elevations using the specially fabricated aluminium copings shows the fruits of this attention to detail. The low-rise section of the building, which sits further down the hill and is accessed externally by short flights of steps to north and south, largely comprises a loggia which encloses the open kitchen/dining/living space. The glazed door folds back to open four central panes – two are fixed at the edge – allowing access to a sheltered patio and outdoor dining area adjacent to the entrance on the south side, and a large lawned area to the north. In total there’s around a 7.5 metre possible aperture on either side. Despite the apparently very formal nature of the plan, “nothing is symmetrical apart from the loggia window,” says Cashin.
Materials & engineering While the focus was on creating a dynamic, modern family home, at the same time, says Cashin, “we were always conscious of trying to bring the old house into the new.” Therefore, brick was the obvious choice for the exterior, with the geology of Hampshire being of chalk

and clay, and a Michelmersh Freshfield Lane rustic brick was chosen for virtually the entire cladding, bar a couple of aluminium panels.
However fitting with the designers’ aim
of “looking to the past to help inform contemporary design,” the joints were raked out by 10 mm to offer greater relief to the walls – “much more depth and variety,” says Cashin. He adds: “We always think of every detail, even at the very beginning of a project.”
The structural engineer specified a steel truss frame, due to the need for a cantilever, and some large spans (up to 11 metres). The walls are brick, but some brick slips were used, such as for soffits. The cavities are extra-wide at 250 mm, hiding all the guttering within them to avoid impeding the exterior aesthetic, as well as housing copious insulation to counteract the large amounts of glazing.
The building has been designed to meet Code 4 of the Code for Sustainable Homes, with nighttime purge ventilation thanks to the 8 metre high stairwell to an openable roof light and a tilt/turn window to the north side of the ground floor, providing a chimney effect. Water is supplied from a borehole and aquifer.
