Exceptional shovel-ready opportunity to build in one of Boulder's most sought-after settings. This coveted west-facing 2.5-acre vacant parcel is surrounded by 32 acres of conservation easement farmland, creating the rare sensation of a significantly larger property with exceptional privacy. Set well back from the road, the flat and sun-filled lot offers year-round sunlight and stunning Flatirons views in a peaceful, secluded environment. The property includes an existing well along with valuable groundwater rights of up to 2.25 acre-feet per year from the Laramie-Fox Hills aquifer. Extensive pre-development work has already been completed, including a site plan review, approved septic system plans, pre-installed electrical and approved architectural plans for a modern, minimalist residence featuring approximately 3,300 square feet of finished living space plus a detached art studio (4,445 sqft allowed). Whether you build as designed or refine the plans to suit your vision, this is a rare and truly remarkable opportunity to create a custom home surrounded by open space, privacy, and iconic Boulder views-an ideal offering for both discerning buyers and builders alike.
