The Courtyard House is situated within a prominent conservation area in South West London close to the River Thames. The original house was architect designed at the beginning of the 20th Century. Fraher & Findlay revisited every aspect of the existing building to propose the most efficient use of space whilst creating a strong sense of place within each of the floors. The client wished to fully refurbish the building, adding a rear ground floor and loft extension. Before the completion of Hammersmith bridge which led to major railway development, much of Barnes was dominated by market gardening. Much of the waterfront of the Thames at Barnes around 1820 was covered by market gardens. The orchards, gardens and nurseries were famous for the exotic produce. The design proposal introduces a 'garden/ courtyards and green space into the floor plan. This courtyard brings natural light deeper into the plan creating external environments within the living spaces. Natural ventilation to the rear ground floor room of the original building is maximised whilst providing visual interest and maximizing external amenity space and the connection between the garden and the building. Wildflower roofs to the extension elevate the garden space to the first floor bedrooms, enhancing the gardens aspect, whilst providing a bio-diverse habitat. Supporting information The interior material use was influenced by the owner’s Danish family background with a strong focus on use of natural timber finishes as well as clean scandinavian lines. Brass detailing throughout gives a reference to the original brass features of the arts and crafts house. To avoid a full width rear extension the design breaks up the rear massing of the building, stepping the extension down into the garden to soft then level change that was problematic with the existing house and its relationship with the garden. A garden facing snug room sits nestled into the lower garden level, whilst maintaining a visual and physical relationship with the living spaces to the main house. High level windows capture views up towards the green roof as well as towards the garden, with a feature wrap around rooflight to the kitchen, enhancing the feeling of space.
