“Marcy helped us imagine the possibilities through her vision and sense of space. By bringing the outside in and making sure function and detail were well integrated, she created an inviting and beautiful addition.”

“Collaborating with firemen-clients, Marcy created new comfortable accommodations for three daily shifts in limited space in an historic building on a limited budget. Not easy.”

“Marcy was the architect on my home in the Oakland/Berkeley Hills; the steep grade and odd sized lot made the house a challenge. Marcy . . . always presented several creative options/solutions to problems and listened to how I wanted the space to work.

“The design of our tennis club remodels has created space and flow that enhances tennis viewing and social gatherings. During construction, the builders respect her and her opinions and solutions . . . a critical aspect of the projects.”

"Marcy brings a fresh perspective, and isn't afraid to challenge our initial thinking, which we appreciate. She is successful in working through complex and challenging permitting issues. She knows how to get things done.”

“As lead architect on the Sweetwater, Marcy shepherded a high profile project through design, permit and construction processes. She held onto major design ideas while being flexible when required.”

"Meeting with Marcy in her charming office space always seemed to produce superb ideas for our home. She took what was the worst feature of our house and turned it into what most consider the best. We do."

“We had an unspectacular house in a spectacular setting, and she helped us design our home to match the setting. She took what was essentially a box and made the space architecturally interesting, more coherent, and more comfortable.

"Marcy Jones has designed three remodel updates for our 1929 home . . . has great ideas on how best to use the space within the framework of the old style. Marcy is creative, exacting and budget conscious.”

Shelter and open air connected . . . invites movement and enriches sitting still.

Projects for tennis clubs, fire station, restaurants, music venue requiring renovations of existing structures with established character.

In the trees, overlooking water, framing mountains, respecting existing architectural style, creating something strikingly new . . .


Lower floor and garden of a 1908 Masonic Lodge has been remodeled to house the famous Sweetwater Music Hall in the center of Mill Valley.

The new Sweetwater has become a hub of downtown activity.

Two-story residence with flexible design can be used as a single-family home, a combination living/home workplace or a home for two separate occupants.
