This townhouse located in the heart of Holland Park underwent total gutting and internal reconfiguration. A new full size basement was added requiring underpinning to both party walls as well as tanking all walls and installing a dual sump pump beneath basement level. At ground level an extension was added to the rear, housing the kitchen and living areas. A new decked roof terrace was created with access through a large sliding skylight. The modern staircase linking the basement with the ground floor features a glass balustrade, which allows the oak staircase to be a feature in the main living space.
