Our built heritage is irreplaceable and must be treated with the utmost care.  True building conservation is neither ‘restoration’ nor ‘refurbishment’ but rather sensitive custodianship of building fabric, where possible retaining as much as possible and securing it for the future.

Jane Jones-Warner and Julian Vallis are RIBA Specialist Conservation Architects and Architects Accredited in Building Conservation (AABC).  Between them, they are on the ‘approved’ list of architects and surveyors maintained by three South Coast dioceses.

All members of the Jane Jones-Warner Associates team are actively involved in assisting clients with the conservation of their buildings.  As a practice we are fortunate to work on a large variety of projects of different scales and complexities, ranging from the inspection of large estate properties to the smallest of repairs.

The experience that has been built over many years enables us to achieve a high success rate in obtaining listed building consent and faculty approvals on behalf of our clients.
