CA Design Studio LLC

CA Design Studio LLC is a small residential design practice in Belmont, Massachusetts. The studio describes its own work as planning renovations and additions for older homes — reworking cramped main floors, adding island kitchens and primary-suite additions, and opening houses up to outdoor space. On Houzz it lists architectural design and sustainable design as its services and shows eight posted projects, and it has not collected any customer reviews there. The one organic reference to the studio is a 2024 comment in r/Somerville, where a homeowner answering a request for architect recommendations said they had worked with Chris Arthur of the studio on an interior gut renovation. The company says it works in Somerville, Belmont and Arlington. This is a design practice rather than a building contractor, so a homeowner hiring it is buying drawings and planning, not the construction itself. With no published homeowner reviews to weigh, judge it on the work: ask to see completed projects close to yours in age and scope, and to speak with the owners of those houses.
