About

Our office

Castle Design Co. is a bespoke architecture and interiors office founded by licensed architect and real estate agent, Lesley Castle. We are a full-service firm that provides all phases of design from concept design to construction administration, including construction documentation. With an emphasis on hospitality, high-end residential and retail design, Castle Design Co. guides clients in the development and/or redevelopment of residential and commercial properties.

Our services include but are not limited to: concept design and development of raw land, renovation of existing buildings, residential new construction, construction documentation and permitting projects, interior design for both residential and commercial projects, site planning / massing studies, and specifying furniture, fixtures and equipment (FFE) for various project sizes.

Castle Design Co. takes a holistic approach to design. This means we consider location, environment and placemaking in our projects with an entity approach: we do not separate architecture from interior design nor landscape design, rather they are fluid, interrelated concepts that together create one cohesive project.

Our team works closely with clients, crafting spaces that feel personal and reflective of those who will live or spend time there. We work on projects all over the world, with most properties in California, Hawaii and the US Virgin Islands.
