A House is a renovation of a wooden house that had become an unauthorised structure due to r repeated extensions and alterations since it was constructed 100 years ago. The processes to bring this house back into compliance with the current building regulations and reapply for planning permission involved 1) removing the unauthorised extensions, 2) constructing a new foundation inside the existing structure for seismic reinforcement, and 3) applying fire-resistant wall cladding. The renovation of A House can be used as a case study to explore the possibilities for other wooden structures with similar conditions.
