UPPER GROSVENOR ST
This grade 2 listed building was in such poor condition it had been put on English Heritages buildings at risk register. The roof had fallen in along with most of the floors. Amazingly the grand 1st floor panelled room was salvageable and has been meticulously restored. The house has undergone painstaking restoration to bring it back to its former glory and is now fully linked to the mews house,
a separate property when we started, by way of a double height glass extension which overlooks the 14m swimming pool. The house now also includes parking for three cars, an expansive spa complex and gym, formal dining and reception spaces as well as 12 bedrooms.
