Period properties require design solutions that respect their existing character while making them work for modern life.
River Bee Design combines residential planning, design and regulatory knowledge to help homeowners renovate, extend and adapt period properties while respecting the architectural qualities that make them distinctive.

We specialise in Victorian, Edwardian, and Georgian properties, including listed buildings and conservation areas.

Yes. Listed buildings, conservation areas and planning-sensitive sites are a core part of our work, including Grade II listed conversions such as The Old Mill in Surrey.
The existing building is considered first, including its proportions, materials, architectural character and constraints. The new work is then designed to create an appropriate relationship between old and new.
A period property is generally a building associated with a particular historic architectural period or traditional style. Examples can include Georgian, Victorian and Edwardian houses and traditional cottages.
