3963 Springleaf Lane is a modern, turnkey home on a quiet cul-de-sac in the Wonderland Hills area of North Boulder, where mature trees, nearby open space, Wonderland Lake, Lucky's Market, and Broadway access keep daily conveniences and outdoor recreation close. A spacious covered front porch opens into a bright, airy main floor with a contemporary feel, where a sleek linear fireplace and oversized windows fill the living room with natural light. The layout flows into the dining area and modern kitchen, featuring leathered granite countertops, stainless steel appliances, a five-burner gas range, and a large island with seating and a prep sink. A mudroom links to the oversized attached two-car garage. Upstairs, the primary suite offers vaulted ceilings, a linear gas fireplace, and a walk-in closet with built-ins, while the five-piece bathroom includes a soaking tub, a shower with dual heads, a double vanity, and a private water closet. Two additional upper-level bedrooms each include en-suite bathrooms, and a covered balcony and laundry room add convenience. The lower level is a full height daylight level with substantial natural light and functional living spaces, including a spacious recreation area suited for media, fitness, hobbies, or guests, a bedroom with a large window and closet, a bathroom, and ample unfinished storage. Outdoor spaces deliver a private Boulder retreat without a high-maintenance lot: a shaded wraparound deck extends to a flagstone patio framed by mature trees, xeriscaping, a hot tub, and a built-in stone gas fire pit. HOA-supported maintenance, including snow removal, adds ease, while solar-ready infrastructure and an ADT security system make the home practical and secure. From quiet mornings on the porch to evenings by the fire pit, this is lock-and-leave living that keeps space, privacy, and a sense of home close to Wonderland Lake, restaurants, and community tennis and pickleball courts.
