Welcome to 512 Sierra Avenue—an intelligently updated, five-bedroom residence in Longmont’s sought-after Quail Ridge neighborhood that delivers a rare combination of design, livability, and long-term investment logic in one of Boulder County’s most dynamic markets.

Positioned on a patio-style lot along a quiet street of well-maintained homes, this south-facing property immediately conveys warmth and approachability. A freshly repainted exterior, low-maintenance sunlit front yard, and inviting covered porch create an ideal setting for morning coffee, evening unwinding, or enjoying Colorado’s summer rain in comfort. The scale is intentional: enough outdoor space to enjoy, without the burden of excessive upkeep.
Inside, the main level unfolds as a light-filled great room designed for both everyday functionality and effortless entertaining. Wood-effect porcelain stoneware flooring, soft gray-white walls, and crisp white trim establish a calm, contemporary aesthetic. Tall ceilings and multiple exposures invite natural light throughout the day, while cross-ventilation enhances comfort year-round. The generous dining area connects seamlessly to the side patio, supporting indoor-outdoor living with ease.

The updated kitchen is a standout—anchored by a marble-pattern quartz island with seating, white cabinetry accented by industrial inspired black hardware, and a glossy two-tone subway tile backsplash. A full Bosch stainless steel appliance suite—including five-burner gas cooktop with downdraft, double ovens, and sleek refrigerator—elevates both form and function. A large window above the sink keeps you connected to the outdoors while cooking or entertaining.

Smart lighting, programmable electric shades and a dramatic floor-to-ceiling stacked stone linear gas fireplace with integrated media niche anchor the living space, creating both ambiance and architectural presence. A well-appointed powder room completes the main level.

Upstairs, the home’s thoughtful layout continues. Two bright guest bedrooms with dual exposures share a spacious full bath. The primary suite occupies the southeast corner and feels like a true retreat, framed by triple south-facing windows and additional east/northeast light. A peaked ceiling enhances volume, while the five-piece bath offers dual sinks, soaking tub, separate shower, water closet, and generous walk-in closet—balancing comfort and practicality.
The extra-tall garage is a meaningful differentiator, featuring built-in cabinetry, work area, abundant overhead storage, excellent natural light, and electric vehicle charging—future-ready infrastructure that supports evolving ownership needs.

The fully finished basement expands versatility with a built-in media/library area, two additional bedrooms with egress windows, a full bath, and mechanical room with recently serviced furnace—ideal for guests, multigenerational living, remote work, or hobbies.

Outdoor spaces remain intentionally manageable, including a covered back deck and side-yard patio framed by mature aspens—perfect for dining al fresco without sacrificing weekends to yard work.
