ABOUT

Designed for living, built for life.

Founded in 1999, Rossington Architecture is an award-winning, full-service practice dedicated to thoughtful design and careful project management. Our work centers on residential architecture, including additions, renovations, new homes, multifamily housing and mixed-use developments. Our broader portfolio includes yoga studios, rock climbing gyms, a corporate retreat in Shanghai and other commercial spaces.

Grounded in modernity, our architecture takes shape through a close reading of each project’s site, existing conditions and surrounding community. We work closely with clients to understand how they live, what they value and what they hope to create. Clean forms, considered proportions and purposeful detailing bring these influences together in spaces designed for everyday use and lasting relevance.

Environmental responsibility is integral to our practice. Working with clients and builders, we develop practical, sustainable solutions that balance design ambitions with budget, code requirements and the realities of construction. Our decisions consider both the people who will inhabit a space and the project’s relationship to its neighborhood and the wider environment.

The projects presented here are the work of many hands. Contractors, subcontractors, engineers, landscape architects, interior designers and color consultants contribute essential expertise and craftsmanship, while photographers capture the completed spaces. Above all, we thank our clients, whose trust, ideas and engagement make this work possible.

We hired Phil as our architect on a large scale remodel and he completely reimagined the space. It was a challenging footprint to work with but his vision transformed our home and we are thrilled with the results!

I worked with Phil on 2 different projects. First, a 3 unit building after a fire and then a 4 bedroom new house. Phil Rossington was my architect on a 3 unit building in the SF Marina after a fire. Phil is the best to work with - very creative, thorough, professional, honest and easy to work with. He was involved with the project until the end and I would highly recommend him. I would love to do another project with Phil!

Phil has designed the last two homes I lived in. The first one I purchased directly from the contractor and loved Phil's design and sense of space. The second home he designed for me was a total build from the ground up of a 2 unit building in SF that was destroyed in a fire. I wanted to go in a different direction on this one and Phil came up with an amazing design. He is awesome to deal with and very straightforward. He made great suggestions some I listened to some I did not. To be honest most of the ones I didn't listen to I now regret. I didn't have the vision he had and wish I had been more open minded. I honestly cant say enough about the guy - he is great.

I have worked on 3 big projects with Phil which should tell you something in itself. The last one was a complete tear down and Phil helped me manage the project while I was on the East Coast. He is a complete professional, helped with some very creative solutions and is extremely easy to work with. He listens very well and helps the client hone in on exactly what he/she is thinking. His attention to detail is really strong as well. I get many people asking me who I used for my house. I recommend him unconditionally.
