Perched atop the crest of one of Mapleton Hill's most desirable streets, 403 Mountain View has it all. Historic character, strong architecture and an unbeatable in-town setting give this home a presence that is immediately distinctive. Inside, original details are balanced by thoughtful updates, creating rooms that feel warm, collected and beautifully livable. A dramatic glass atrium brings exceptional light into the heart of the home and captures seasonal and mountain views, while generous living and dining spaces flow easily for both everyday life and entertaining. A private lower-level entrance creates an independent living arrangement with two bedrooms, a separate bath and generous living space, ideal for extended family, long-term guests, an au pair, or simply added privacy and flexibility. The primary suite is equally considered, with a beautifully appointed bath and steam shower, while three generous in-wall/eave storage areas on the upper level provide valuable additional storage.Outside, the home really comes into its own. Multiple porches and patios create places to gather, dine and unwind throughout the day, while the private pool and waterfall bring an effortless resort-like quality to the setting. An 8' x 10' garden/storage shed tucked behind the pool adds convenient additional storage. Seller has also secured City of Boulder Landmark Alteration Certificate approval for a proposed one-car garage and enclosed mudroom-an unusual and valuable opportunity in historic Mapleton Hill. Flatiron views, mature landscaping, an electric gate and 220V car charging station add both character and convenience. There is also one off-alley parking space at the rear of the property.And the location is next to impossible to beat: just moments from Pearl Street, downtown restaurants and shops, neighborhood cafes, Mt. Sanitas and some of Boulder's best trails. This is Mapleton Hill living in its most complete form-private, connected, architectural and distinctly Boulder.
