Chiswick garage infill site digs down into a Passivhaus home
PHT member RDA architects and team, recently received certification for a beautifully bespoke London Passivhaus home. Overcoming a fraught three yearlong planning process, the detached home for a private client sits quietly on the site of a former garage in Chiswick.
Deceptive from its exterior appearance, the house boasts three bedrooms, generous living space and outdoor amenity achieved through the addition of a basement level courtyard. Exposed concrete walls, and a bespoke timber staircase are flooded with vast amounts of natural light to create a warm and sub terrain home.
