Split House, Sevenoaks, Kent Split House is a new-build, three-storey family home set within a steeply sloping site in Sevenoaks, Kent, positioned between two detached houses on land falling northwards. A conventional stepped arrangement down the hill would have produced a sequence of predominantly north-facing spaces with limited direct sunlight and a weakened relationship to the garden, which naturally sits to the south. The proposal instead divides the mass into two parallel volumes, separated by a central glazed link that accommodates the primary circulation. This glazed element is set back to form a small courtyard, introducing planted space into the centre of the plan and allowing daylight to penetrate deep into the building. A silver birch tree anchors this courtyard, mediating views and marking the vertical movement through the house. The two volumes follow the topography through a series of staggered levels. The northern volume is set approximately 1.2 metres below the southern volume, resulting in six interlocking split levels across three storeys. The central stair within the glazed link organises movement between these levels, establishing a clear spatial sequence while maintaining visual continuity across the house. To the rear, a stepped garden is cut into the slope, forming a series of planted terraces that extend the living spaces outward from the lower ground floor. This arrangement strengthens the connection between interior and landscape, while ensuring that each level benefits from access to light, outlook, and external space. Materially, the building is conceived as a pair of robust volumes with carefully framed openings, contrasted by the lightness of the glazed central link. The composition balances solidity and transparency, responding directly to the site’s topography, orientation, and surrounding context.
