About this home

Public Remarks: Extremely rare opportunity in North Boulder to build your dream home on a nearly 3/4 acre park-like lot in coveted Githens Acres. Located on the edge of Boulder and literally five minutes to downtown! Amazing, flat lot with huge trees and views. Renovate, add on, or start from scratch as the value is primarily in the land. Excellent water rights come with this property, including 1 share of water rights to the Silver Lake Ditch, an irrigation well, and a household well.
