The roughly 40-foot-tall structure is expected to yield around 6,040 square feet, including 3,800 square feet of housing and 2,240 square feet for the ground-level garage. Unit sizes will vary, with four studios, a one-bedroom unit, and a two-bedroom penthouse occupying the top floor and part of the third floor.
The unusual residential complex will also feature a large shared living space on the second floor, connected to three studios and the common laundry room. The ground floor will include the entry lobby, four-car garage, and connection to a studio apartment at 74 Laidley Street. The top floor will include a common open deck with seating and limited landscaping.

The renderings offer a glimpse of the familiar contemporary modern style. The exterior will be clad with a mix of limestone tiles, smooth concrete, stucco, and teak wood panels.
The property owner is listed as a San Francisco-based individual, having purchased the existing house in November 2025 for $1.8 million. Construction is estimated to cost around $8 million. The timeline for completion has not yet been shared.

My best guess is that there’s a wealthy tech individual who somehow has a plan to have employees, friends or family stay with him on a regular basis and loves the idea of everyone having their own space for mid-term stays. Option 2, a bizarre co-living situation. Option 3, really likes the idea of the cashflow of renting those units out.
Dear little Laidley Street has become Tech Titan Row. This Gen Xer misses the hell out of 1990s-era San Francisco.
