About the property

Gated South Boulder Contemporary — Renovated 5-Bed, 0.34-Acre Oasis

A rare combination of privacy, volume, and high-end detail defines 865 Kalmia Avenue. Set behind an electronically gated private drive on a generous 0.34-acre parcel, this contemporary residence has been re-envisioned for modern living while retaining a warm, rustic sensibility. Enter through a striking foyer anchored by a quartzite accent wall into main-level living defined by wide-plank rustic oak flooring, a tumbled marble fireplace surround with reclaimed wood mantle, and designer lighting throughout.

The completely redesigned kitchen is a showpiece—paneled, top-tier appliances, a honed black granite island, hickory cabinetry and Calacatta Gold marble countertops provide both style and performance for cooking and entertaining. A generous main-floor primary suite features vaulted ceilings, a private deck, and a luxurious en-suite with a solid concrete soaking tub and a steam walk-in shower clad in whimsical designer tile. Thoughtful touches like level 5 drywall and a dedicated wine room elevate the everyday.

The lower level continues the high standard with a second primary-style suite, two additional bedrooms, a contemporary bath with glass penny tile, a sun-filled rec room, and an exercise room—offering comfortable separation for guests, family, or home-office use. Laundry is oversized and finished with herringbone white-washed brick flooring. Outside, expansive decks, a pergola and an intimate patio are framed by mature trees and meticulous landscaping to create a private outdoor living experience rarely found this close to central Boulder. A standing seam metal roof and modern mechanicals provide durability and low-maintenance ownership.

This home is ideal for buyers seeking move-in condition in south Boulder with superb indoor-outdoor flow, flexible suite-level living, and immediate access to trails, neighborhood amenities, and the cultural attractions of downtown Boulder.

Editorial market perspective

South Boulder remains one of the market’s most resilient submarkets thanks to proximity to open space, strong schools (BVSD), and convenient shopping/commute routes. In 2026 the overall Boulder market shows measured appreciation—entry and mid-tier homes move quickly while the luxury segment experiences more selective buyer activity. Upgraded, private properties with turnkey condition (like this home) still capture strong buyer interest and relative price stability. For sellers, pricing competitively against recent renovated comps and presenting a thorough renovations/permitting packet will be critical. For buyers, the property offers a high-quality, low-hassle acquisition with immediate lifestyle upside in a neighborhood prized for outdoor access and central-Boulder convenience.
