Interactive floor plan: The Houl, Scotland
The Houl, a contemporary single-storey family home in Dumfriesshire, Scotland, reinterprets the traditional Scottish 'longhouse' while incorporating net-zero carbon credentials. Designed by Simon Winstanley of Simon Winstanley Architects for his own use, the dwelling is situated within a concave cranny on a west-facing slope, offering views of the River Ken valley and the Rhinns of Kells hills. Its design features a low-slung, streamlined profile utilizing a lightweight steel and timber frame construction. The exterior is clad with untreated cedar weatherboard, which is intended to age to a natural silver-grey, and boasts long monopitched roofs finished in pre-weathered grey zinc. The main roof's slant follows the natural slope of the hillside, with a shallower rear roof pitch designed to draw morning sunlight deep into the house.
The principal open-plan living areas are strategically positioned along the site's contour to maximize the panoramic views across the valley, while ancillary spaces are discreetly recessed at the rear. The entrance, located on the north-east side, benefits from the roof's overhang, providing shelter from the strong prevailing south-westerly winds common in the region. Beyond its aesthetic integration with the landscape, The Houl is a testament to sustainable construction practices, with all excavated material being reused on-site to minimize environmental impact.
Energy efficiency is a cornerstone of the design, leading to the home achieving net-zero carbon emissions. This is accomplished through adherence to PassivHaus insulation standards in the walls and roof, complemented by a reflective thermal membrane on both the inner and outer faces of the timber frame. The primary heating mechanism relies on passive solar gain, facilitated by extensive high-performance triple-glazed windows and external doors, which boast a very low u-value of 0.7. Supplemental mechanical heating is provided by an air source heat pump and a whole-house heat recovery ventilation system, ensuring consistent indoor climate control. Additionally, a wind turbine generates supplementary electricity, further reducing the home's reliance on external power sources.
A key design philosophy was to integrate these advanced 'green' technologies seamlessly into the architecture, ensuring they do not detract from the house's clean lines and subtle design. With the exception of the wind turbine, the eco-hardware is deliberately concealed, allowing the architectural integrity and simple elegance of the home to remain uncompromised. This approach ensures that The Houl is not merely a collection of sustainable components but a cohesive dwelling where performance and design are equally valued, embodying the principle that "God is in the detail."
