Brockenhurst House began as a distinctive 1970s chalet-style property nestled on the outskirts of Brockenhurst, in the heart of the New Forest National Park. Purchased with a clear vision in mind, the new owners set out to transform the aging structure into their ideal lifelong home—one that gracefully supports the evolving needs of later life without compromising on beauty, sustainability, or design integrity. A central ambition of the project was to seamlessly integrate accessibility into a contemporary architectural language. The result is a refined, low-carbon dwelling that balances modern design with future-proofed functionality. The design brief focused on three key goals: reconfiguring the layout to allow for flexible living, delivering a sustainable overhaul of the building’s fabric and systems, and strengthening the relationship between house and garden. A modest single-storey extension to the side and rear enabled a thoughtful reorganisation of internal spaces, improving flow and spatial hierarchy while visually and physically drawing the landscape deeper into the home. Brockenhurst House exemplifies how thoughtful architecture can elevate everyday living, transforming a tired home into a high-quality, low-carbon contemporary home to support all needs in the future. The design rearranges the ground floor, maximising the space available and enhancing the functionality. The scheme extends and opens up the kitchen and dining area, increasing connectivity to the rest of the home and the large garden. The design considers passive heating and cooling strategies with external shading elements, and strategic window placement. Enhancing the connection between the house and the garden is a key aspect of the proposal; the proposal extends into the outside space as a natural extension of the home, viewing the garden as a series of external rooms and spaces with a strong connection to the internal activities. A new, detached garden yoga studio room is placed at the far end, clad in matching stained timber to echo the design of the home. As part of the whole proposal the house will be thermally upgraded, increasing the energy performance, with the aim of delivering a low energy, comfortable home that has a reduced reliance on the national grid.
