Pembury Gardens proposes a revitalization of an existing housing site through a multi phase approach of addition and new build, refurbishment, and outdoor design. The project site is located on Pembury Road in Hackney, London, and is adjacent to Pembury Circus, a newly constructed housing project by Fraser Brown Mackenna Architects. Initial massing studies were used to determine the optimal form to maximize solar gains during cold winter months. Analytic simulations were then used to test various design parameters to optimize indoor environmental conditions. Key considerations included solar access, indoor/outdoor comfort, thermal performance, and embodied carbon.
