808 & 812 Spring Drive. Incredible opportunity in Mill Valley to create your dream home on two sun-drenched lots in Tam Valley. First time on the market in over 75 years and steps to GGNRA open space, 808 Spring is a relatively flat 10,300SF lot with a 3bd/1ba home in need of TLC. The adjacent 9,680SF land is gently sloping with plenty of flat area for another spacious home, or create a large yard and guest cottage. Both lots are very private with very little street traffic and the location is easy access to downtown and HWY 101. This is the opportunity of a lifetime for your clients who have been wanting to build their new home in Mill Valley!
