An ambitious and complete rebuild and extension of a late Victorian terraced house in Brockley, south east London.The existing house suffered from the addition of poor quality extensions and structural problems. The ambitious solution is to completely rebuild the house. This rebuild is to be achieved with a design of uncompromising high-quality architecture.Our proposals responded to the local context and the predominance of poor quality permitted development extensions. Looking to maximise the potential of the property a detailed analysis was undertaken of the rules that allow such development. The proposal radically challenges what can be achieved with this most typical of house extension types and then takes it to another level by rebuilding the whole house. The approach taken has built upon the work we outlined in our RIBA article published in spring 2017.
