Rossington Architecture

Rossington Architecture is a full-service architectural firm dedicated to excellence in design and design management. Founded in 1999, the firm's work focuses on residential projects, including additions, renovations, new homes, multi family housing and mixed use. Other projects have included two yoga studios, two rock climbing gyms and a corporate retreat in Shanghai, China and various commercial work.

Detailing is kept purposefully clean, simple and timeless.

We are strong proponents of environmentally sustainable projects and enjoy working with clients and contractors crafting green, workable solutions based on myriad concerns, including budget.
