Hackney Lofts
Hackney, London
Hackney Lofts is a remodelling and deep retrofit of a neglected office building to provide two spacious, light-filled apartments. By peeling back layers of clumsy adaption and fit-out, the height and character of the historic building was revealed and opportunity given for thermal upgrades that vastly improve the energy performance of the space.
The careful removal of floors and ceilings revealed aged timber roof structures which now dominate double height living spaces. This is complemented by light touches of new joinery - a box jointed staircase, carefully crafted oak shelving and kitchens with contrasting deep-blue recycled plastic. New roof terraces were designed into each apartment, carefully slotted behind parapets and chimney stacks to protect views from the surrounding conservation area.
Thermal comfort is at the core of the design - dual aspect living spaces maximise cross ventilation, with new skylight openings increasing air flow and drawing natural lighting into the plan. The project was completed with the highest ambitions for energy efficiency - incorporating breathable internal insulation, air-tight linings, full house ventilation with heat recovery, and efficient air-source heat pumps for all heating. Since completion in January 2023, the heating and cooling demand has been measured through energy consumption and resulting bills. As a result of the above design strategy with regards to airtightness and MVHR, to heat/cool the entirety of the space only requires 30kWh/sqm/year.
