About this home

Public Remarks: Make 2736 3rd St. your Boulder mountain retreat-in town. This custom contemporary home sits at the base of Mt. Sanitas in the most exclusive area of The Newlands neighborhood. A uniquely private 15,000+ SF site slopes to the east providing spectacular views of Boulder and the plains. Within walking distance of Pearl Street, N. Boulder Park, and Ideal Plaza; there is no better location. Steps away from Mt. Sanitas and the extensive network of Boulder Open Space trails. Greet the morning with sunlight filling the east-facing windows; prepare meals in the gourmet kitchen; entertain guests in the open-flow main level and expansive outdoor decks; then relax in the evening by the lighted custom waterfall with a bottle of wine from your private cellar. The home offers opportunities for expressing your personal tastes, or you can move right in and enjoy your space. The lower level features two bedrooms, climate-controlled storage, and a workshop designed to be finished into a junior suite.
