Presenting 1120-1130 Alpine Avenue, an exceptional 0.93-acre (40,349 sq. ft.) redevelopment parcel situated in the heart of Boulder's highly coveted North Broadway neighborhood. Currently improved with two medical office buildings totaling 13,657 SF, the site offers a generational canvas for a landmark mixed-use project in a notoriously high barrier-to-entry submarket.

Innovative Residential Design: 56,000 SF of flexible, subdividable living space across four levels. Efficient "paired floor" configuration allowing upper spaces to be accessed from within lower units, permitting for endless combinations, from expansive two-story lofts to single-story studios. Premium Ground-Floor Retail: 16,000 SF of high-bay (12') retail space anchored by an intimate courtyard pocket park. Spaces can be leased separately or combined with residential units for the ultimate live/work amenity. World-Class Rooftop Amenities: 15,000 SF private recreation deck with rooftop pool and lush gardens. Intelligent Parking Solutions: Two levels of underground parking with 140 exceptionally wide (10') spaces for easy access and loading. Strategic Positioning: Located just west of Broadway, the site sits immediately south of the brand-new City of Boulder Municipal Campus, guaranteeing dense, reliable daily foot traffic. Ultimate Walkability: Directly across from the North Boulder Ideal Market Shopping Center, providing residents and tenants with effortless access to Whole Foods, Sweet Cow, Santos, and other essential daily staples.

    "West Pearl is truly a neighborhood unto itself, with a variety of shops & cafes and easy access to trails. Start your day with some tea and scones at Spruce Confections, enjoy browsing various antique stores and Two Hand Paperie, then select a bottle of wine at West End Wine Shop. Lolita's is conveniently located across the street to pick up last minute groceries for dinner, or you can enjoy a slice at Nick and Willy's and have some confectionary treats at Piece, Love & Chocolate. Settlers' Park is just down the street, as well as the trail heads to Red Rocks & Sanitas, and the Boulder Bike Path. When you live here, everything that makes Boulder so wonderful is only steps away!"
