What's in the Works
Lane Partners is transforming 222 East 4th Avenue in downtown San Mateo into a new mixed-use development. The proposed project will bring new Class A office space to the downtown, new housing in the form of ten (10) 100% affordable units, and will create vibrant new retail designed for a future grocery store and a tap room style restaurant with indoor/outdoor seating. The design also contemplates a community gathering space in the form of a new public plaza at the corner of East 4th Ave and Ellsworth street.
This plaza is envisioned as an activated and engaging public area with natural overflow from the retail businesses with seating, plants and landscaping, and wider sidewalks. We are excited about the opportunity to contribute to the growth of downtown San Mateo in a way that fits the character and sense of place that makes this community unique.
What's There Now
The site is currently located on a city block close to Caltrain Station in downtown San Mateo.
