Rare Dual-Lot Development Opportunity for builders, developers, investors & custom home buyers. This is an exceptional chance to secure one or both of two adjacent, separately buildable lots in an established Boulder neighborhood. Purchase 1920 Grape Ave individually for $725,000, or acquire both 1920 & 1930 Grape Ave for $1,300,000 and capitalize on the efficiencies of designing and constructing two homes simultaneously. Construct both homes to significantly reduce cost & maximize economies of scale-creating a compelling infill opportunity that's increasingly difficult to find in Boulder. For custom home buyers, this lot offers the perfect canvas to build the home you've always envisioned. Or purchase both lots to create a larger private estate & preserve additional open space and privacy, or develop one home while retaining or selling the other. Vacant residential lots in established Boulder neighborhoods are exceptionally scarce, and opportunities to acquire two side-by-side parcels are even rarer. Whether you're looking to build one extraordinary custom home or develop two signature residences, this offering provides outstanding flexibility, value, and long-term potential.
