A 48 unit development of volumetric dwellings for social rent designed to meet the 'Gold' Standard for sustainability. The project was awarded funding from the Scottish Government under the Greener Homes Innovation Scheme; a scheme which strives to invest in modern methods of construction and reduce carbon emissions in housing. Constructed off-site using a SIP system, the dwellings achieve unprecedented levels of energy performance; both in terms of minimal heat loss and air leakage. This fabric-first approach, together with renewable technologies, results in dwellings which produce 50-60% less carbon emissions.
