After a drawn out, 13-year process, architecture firm Arquitectonica has rolled back the years on its design for the final installment for Trinity Place on San Francisco’s Market Street. The firm has reverted to a design it originally conceived back in 2006 and had approved in 2007. However, the final phase required much back and forth and Arquitectonica and San Francisco‘s Planning Department have just now found accord and are moving forward.

Since Arquitectonica submitted its original plan in 2003 for the site, 13 years have passed along with numerous iterations to the project.

Originally, 1,410 housing units had been planned, but this proposal was altered in 2006 due to complaints from locals. After that, the final third phase of the project lay in limbo, being changed and changed again in the process.

But while the project stalled, the area has also changed. When Arquitectonica cofounder Bernardo Fort-Brescia submitted yet another set of plans last week (that were very close to the 2006 scheme), the San Francisco Department acknowledged that perhaps Mission/Market Street had caught up and finally gave it the green light.

Prior to Arquitectonica’s inception, the 4.5-acre plot was occupied by a motel that in the 1970s had been converted into apartments. Now, two, 24-story cubic volumes rise up, interlocking and overlapping with various elements, all of the same simple orthogonal nature.

The structure houses 440 units, “360 of which are rent controlled,” the firm said, settling one of the earlier disputes. This, however, is just the “first phase” (which has already been built) of Arquitectonica’s overall plan, which will offer a whopping 1,900-units.

Phase two lies on the same plot. It boasts 105 more units with 21,000-square-feet of retail space, while the third and final phase will use a Tetris-like, golden “L” shape to house 915 new residences. They don’t come cheap, either, with prices starting at $2,775 for an unfurnished “junior one bedroom.”

“We wanted to start with something very graphic and pure compared to the background of San Francisco, and then the composition changes personality from one building to the next,” said Fort-Brescia. “By the time it reaches Market Street, we’re trying to create a more subtle streetscape.”
