Our clients aimed to transform an aging extension, originally designed decades ago when they first acquired the property, which no longer met their functional and environmental needs. With one half of the couple being an academic in the field of climate change, there was a strong responsibility to create a building aligned with their values. FPA was tasked with reimagining the remodel as an energy-efficient, contemporary extension that harmonized with their home and lifestyle while fulfilling their aspirations for a sustainable future. We responded with a modern intervention distinct from the original building fabric. The design, with its unique forms, draws inspiration from Kingston’s industrial heritage and its connection to the coconut industry. Referencing the saw-tooth roof associated with Middle Mill - once home to “The Patent Cocoa Fibre Co Ltd” - the new volumes honour the structures of the town’s manufacturing past. Faced with strong resistance from the Local Authority, which favoured a more traditional approach, the clients’ belief in the design proved instrumental. While initial adjustments under Permitted Development were rejected, permission was ultimately secured through a successful appeal, reinforcing the architect’s and clients’ commitment to a contemporary design. The open-plan extension employs varied ceiling forms and carefully positioned openings and skylights to distinguish functional areas, adding spatial interest while guiding views toward key focal points: the mature Yucca tree beyond the kitchen, the larger maple tree and expansive garden, or even the sky itself. To further emphasize the zoning, pastel colours are used throughout to enhance and complement the architecture, with pink hues signifying objects and differentiating spaces. In the kitchen, a bold multicoloured terrazzo worktop makes a striking statement, paired elegantly with oak cabinets. The design features a double-soothed façade that frames the sunken patio, with the new volumes subtly echoing Kingston’s industrial heritage. Modern stock bricks are used to tie the extension to the existing house, with varied brick bonds forming an abstract motif that adds texture and depth. From the outside, the extension appears deceptively compact, yet it unfolds into a surprisingly spacious interior. The existing structure has been extensively retrofitted with insulation, significantly improving energy efficiency. Heating and hot water are provided by an air source heat pump, working alongside a mechanical ventilation system with heat recovery to maintain indoor comfort. Additionally, a 7,500-litre underground rainwater storage system supplies water for the larger-than-usual garden during the summer months.
