Our client approached us to assist them in designing a side infill and loft extension that had sustainable principles at its very core. The design developed with clever strategies to achieve high amounts of natural light but not excessive solar gain, views without loss of privacy, natural ventilation and solar control systems. Planted areas, green roofs and a carefully planned garden complement and enhance an aesthetically refined architectural language. Signature vibrant colours make the spaces come to life. Mitchell + Corti has brought new life to a London home with sustainable and environmentally conscious solutions. The project is a side, rear and loft extension to a mid-terrace family home located in the heart of Queens Park conservation area. The net-zero carbon residential retrofit project provides seamless integration of sustainable systems without compromising on aesthetics. To achieve the A-100 energy rating, sustainability, airtightness and energy targets were met by employing a diverse range of solutions. These included key elements from external blinds and solar panels, an ASHP, MVHR air handling unit and triple-glazed windows and doors, through to wildflower roofs, reclaimed tiles and natural clay walls.
