The original house was pulled down and a new Hauf House was commissioned and built onto a complicated pile foundation system. The whole under-laying sub-soil is very heavy London clay and for this reason the pile foundations were chosen, the entire hard landscaped areas around the house were built up on 1m+ deep compacted, free draining backfill so that water tables were effectively dealt with. This was a major concern of the client and one we worked closely with him to make work.
