Interiors The external materiality was brought through to the interior spaces, but in a softer palette, to create a sense of continuity. The smooth white walls of the apartments create a spacious feel within a limited footprint. Charcoal from the external steel and stonework is re-imagined in the interiors through grey tones throughout the kitchens and bathroom vanities. Interior palettes were kept neutral to form a backdrop to any individual styling by owners. The result is light, bright and seemingly spacious contemporary living spaces. Sustainability The project was rationally designed with energy modelling software, by consultants, HereToday. Due to the passive green approach to the architecture, the energy demands were minimal. Detailed planning of sustainable elements guided the energy efficiency decision making, as various thermal performance options were evaluated against the cost and value. The open atrium space between the blocks, apartment layouts, fenestration sizes and orientation capitalise northern solar gain, thus enhancing day-lighting and natural ventilation. This passive thermal design, whilst being energy efficient and sustainable, also leads to greater comfort levels, residents’ well being and even increased productivity. Other efficiency measures considered were the use of red clay face-brick walls to reduce embodied energy and future maintenance. Internal high The Chelsea level glazing aided in maximising the natural light egress, whilst extra seals on fenestration reduced air leakage and thermal transfer. Reduced shading allowed more winter solar gain and a ring main hot water system to reduce hot water usage. Multi-layered plumbing pipes and low pressure composite hot-water storage tanks with high specification insulation were used to reduce hot water standing losses as well as the low flow water fittings with low wattage lighting and energy efficient appliances. An option at a later stage is to install a photovoltaic system in order reduce the base load demand. 47
