The Bernardi Group, a trusted Boulder real estate agent team led by Karen Bernardi, is proud to represent this listing.
A Floor Plan Built for Flexibility
Opportunity takes many forms, and this home gives buyers the flexibility to make it their own. With 7 bedrooms, 2 kitchens, 2 primary suites, and 2 laundry areas, the floor plan is designed for a variety of living arrangements, whether that means multigenerational living, space for extended family, potential rental income, or simply more room than a typical single-family layout provides. Step inside to warm wood floors, a bright living room lined with built-in bookshelves, a wood-burning stove, and a striking wood-paneled ceiling that immediately sets this home apart.

Why This Layout Appeals to a Range of Buyers
Few Boulder listings offer the kind of built-in flexibility that House of Many Doors does. For multigenerational families, having two full kitchens and two primary suites means aging parents, adult children, or extended family can share a home while still maintaining genuine independence and privacy. For buyers exploring rental income potential, the dual living arrangement offers built-in flexibility, though buyers should independently verify current City of Boulder zoning and rental regulations before pursuing any rental use. For buyers simply wanting more space, the sheer scale of this property, both in square footage and lot size, is hard to match elsewhere in Boulder.
A Wooded, Private Setting in the City
Set on a wooded lot with mature evergreen and deciduous trees, this property offers a level of privacy that feels far removed from typical in-town living, while still being within Boulder city limits. The lot abuts a ditch and includes a dog run and kennel area, storage buildings, and a spacious deck and patio, making it well suited for buyers who want outdoor space to match the home's generous interior square footage. It is the kind of setting that is increasingly difficult to find this close to the center of Boulder.
Schools Serving This Address
This property falls within Boulder Valley School District Re2, with Crest View Elementary, Centennial Middle School, and Boulder High School as the assigned schools. As always, families should confirm current attendance boundaries directly with the district before making a decision based on school assignment.
What to Know Before You Tour
A few practical notes for buyers considering this Boulder property:
- Buyers interested in rental income or accessory living arrangements should independently verify current City of Boulder zoning, occupancy, and rental licensing requirements before finalizing plans.
- A seller's property disclosure is being provided as part of this listing, a helpful resource that should still be paired with a professional inspection.
- This property does not have an HOA, giving buyers flexibility but also full responsibility for exterior maintenance and any future changes to the home.
Questions about financing, taxes, zoning, or legal matters tied to a purchase like this one are best directed to a mortgage lender, tax professional, land use attorney, or the City of Boulder directly. The Bernardi Group can help connect buyers with trusted local professionals.

Character That Sets This Home Apart
Beyond its unique floor plan, this home offers genuine architectural character that is hard to replicate. The wood-paneled ceiling, built-in bookshelves, and wood-burning stove create a warm, established feel, while skylights and cathedral ceilings bring in natural light throughout the main living areas. For buyers who want a home with real personality, not just square footage, this property offers a rare combination of both.
