What Our Clients Say About
Extension Architecture
Decades Of Architectural Experience In Camden
We take great satisfaction in having an open and inclusive design process that includes the client at every turn. Our goal is to provide an excellent response to design inquiries, and we approach sketching, modeling, and visualization in an iterative manner to develop proposals. One of our projects in Camden is “33 Christchurch Hill”, this property was proposed with a single storey extension with an open plan. The purpose of this house addition is to improve the connection between the property and a sizable garden. There is an uninterrupted view of the garden from the glazed evening room, and a newly constructed dining room with oak-framed sliding doors that opens to a landscaped garden.
