    Seller Financing Available. The beautifully preserved past meets the exciting present in this carefully updated and diligently maintained historic Mapleton Hill home. This fine Boulder 4BD/3BA landmark awaits its next generation of lucky residents with an expansive modernized layout, a wealth of original and period-appropriate architectural details, and phenomenal poolside outdoor space. Built in 1895, The Law House is a Gothic Revival masterpiece built from stone quarried from Mt. Sanitas. Inside, you'll find tall tin ceilings, original fir floors, stained glass windows and exceptional millwork paired with thoughtfully selected lighting, windows and doors, Cleveland Art and Antiques handblown light fixtures and Sonos speakers. A charming covered porch and gracious foyer open to a sun-kissed layout perfect for peaceful relaxation and lavish entertaining, including a fireplace living room, elegant formal dining room and a stately library with breathtaking woodwork, a Murphy bed and a hidden passageway to both the lower and upper levels. The open gourmet kitchen boasts a skylight, custom cabinetry, honed raw-edge Australian granite and upscale appliances, while an adjacent guest bath and laundry room add convenience. Grill masters will love the large deck's Lynx summer kitchen. Below, the newer saltwater jetted pool spa is surrounded by manicured gardens and tall trees for optimal privacy. A handsome fir staircase leads to the upper-level private quarters, including a luxurious owner's suite with a spa bath and walk-in closet. Two secondary bedrooms & a full bath complete the top floor, while the walkout basement provides a vast footprint for media room, home gym & game room use. Completely remodeled in 2006, the home includes upper-level HVAC and mini-split/radiant heat on the main and lower levels. Plans are available for a primary bathroom and closet remodel and a basement expansion with a depth increase. Coveted Mapleton Hill Historic District close to EVERYTHING.
