We are starting works on the refurbishment and extension of an existing 1720’s Grade 2* listed terraced 7-bedroom family dwelling of around 390 m2 close to Marble Hill House, including the construction of a potentially full width single-story rear extension with replacement of the existing rear infill kitchen extension, the conversion of the existing lower ground floor dining area and adjacent room to form an independent one bedroom nanny accommodation. We also redesign parts of the first & second floors to provide additional en-suite bathrooms, as well as an overall upgrade to the building envelope and thermal performance where possible, in close cooperation with the local conservation department.
