Chenery House, pictured below, is the largest private estate in San Francisco. Gracewood Design was commissioned by owner Bob Pritikin, to embellish the entrance to the mansion - grand steps leading to a large portico.

Chenery House, Exterior

We choose a classic greek key design to compliment the Greco-Roman flair of the mansion and paired this with another strong geometric pattern, the compass rose, at the center of the portico. The greek key graces every other stair tread and winds around the front and sides of the portico. We created a complimentary pattern to the greek key for the stair risers which captures the visitors eye as they approach the mansion along the lovely walkway with its center fountain and sculpture.

The concrete surface had previously been painted. The entire surface was sandblasted and then the pattern was applied using stencils and a latex resist product. The surface was then acid stained to create the amber-wheat color, and the latex resist removed to reveal the pattern underneath. The surface was then sealed with a matte sealer, leaving a natural concrete finish.
