The refined plans for a pair of 41-story towers to rise up to 420 feet in height upon the San Francisco Honda site, on the southwest corner of Market Street and South Van Ness Avenue, are moving forward and about to undergo a required environmental review.

Originally envisioned to yield 767 residential units over 20,000 square feet of retail space, with a garage for 275 cars and 265 bikes below, the refined plans for the 10 South Van Ness project now include up to 984 dwelling units over 30,000 square feet of ground floor retail space and a garage for 518 cars and 397 bikes.

And should the public or Planning balk at the double tower plans, the development team has drafted plans for a single 55-story tower to rise up to 610-feet on the Hub District site, a design which would yield the same number of residential units, retail space and parking as the two-tower plan above.

We’ll keep you posted and plugged-in as the dualling plans progress.
