Across the street from Wonderland Lake in North Boulder, 4145 Riverside Avenue is a 3-bedroom, 2-bathroom home where the lake, its trails, and the foothills are part of the everyday view. From the covered front porch, the main level opens into one connected space with hardwood floors, a wood-burning fireplace with a stacked-stone surround and wood mantel, and a sliding glass door that frames the foothills and leads to the deck. A row of high windows fills the room with natural light. The kitchen features granite counters and warm wood cabinetry wrapped around peninsula seating that faces the living room, and a dining nook surrounded by windows catches the morning sun. Upstairs, vaulted ceilings give both bedrooms height. One has a custom closet and windows on two walls, while the other opens to its own foothills-facing balcony and includes a custom Murphy bed with built-in storage. The two share a bathroom with a tub and shower. On the lower level, a third bedroom with an attached bathroom doubles as a home office, with laundry nearby. Nearly every major system has been replaced in recent years, including a new roof in November 2026, a heat pump for heating and cooling backed by a gas furnace, a tankless water heater, and a new electrical panel, along with noise-reduction windows, a freshly painted deck, an Ecobee thermostat, and a Reolink doorbell. The insulated attached one-car garage is finished with slatwall storage and connects to the lower level. Outside, the main deck holds a full seating area facing the foothills, and the fenced yard pairs new landscaping with terraced stone garden beds, flagstone steps, and trellises ready for vegetables, perennials, or climbing vines. Residents share members-only open space with a picnic area and extra resident parking, and an underpass leads directly to the Wonderland Lake trails. North Boulder shops and restaurants are close by, and Broadway leads to Pearl Street and downtown Boulder.
