7-22 Systems Ltd is an ecological construction business based in the Southern Isles of the Outer Hebrides, founded by experienced Uist-based Architects. The company was formed in response to the practical and design challenges of delivering best value, high-quality, environmentally sustainable buildings. They produce an architect-designed building system, suited to small to medium-sized construction projects, and provide a turn-key Design and Build construction service.
The 7-22 System utilises off-site prefabrication of pre-insulated components, offering an innovative approach to construction. The team has expertise in delivering bespoke houses, multi-house and mixed-use developments for island and rural communities, worker housing, community projects, commercial units, and tourism accommodation, all to market-leading ecological standards. With a proven track record of delivering projects throughout the Scottish Highlands and Islands and beyond, 7-22 Systems leverages modern methods of construction and a commitment to environmental sustainability.
Their approach emphasizes quality control through prefabrication and a deep understanding of the local cultural and environmental context, climate challenges, and building industry specifics.
Isle of North Uist
A 2-bedroom croft house designed and built on the shores of a sea loch, maximizing views and natural light, with attention to thermal comfort and plywood-lined finishes. The project overcame challenging site conditions with 3m deep peat by using pier foundations in recycled oil drums to minimize ground disturbance and concrete usage.
Isle of North Uist
An award-winning studio house and sauna with a large gable window framing sea views, designed to bring a Scandi lifestyle to Uist. Structural components and cladding panels were prefabricated on-site, with the buildings becoming wind and watertight in two weeks. The project won Best Use of Timber at the 2024 Highlands and Islands Architecture Awards.
Grimsay, North Uist
A modern house currently under construction that cantilevers over tidal rocks, with spaces designed to reveal fine views of the Uist coastline and the Cuillin Ridge.
