About this home

Homes on Happy Valley Road all are highly prized, but several things make this exceptional estate stand above others. First, it not only is removed from street traffic and noise, down a tree-shaded lane; it is wholly invisible from Happy Valley Road. One lives in tranquility and solitude. Second, it is immense: a 3.6-acre lot, with 13,737 sq. ft. of living space in the main dwelling under soaring ceilings, 6 bedrooms, 6 en-suite bathrooms, and 3 half-baths. Third, the estate offers an exceptional venue for outdoor entertaining: a pavilion with elite appliances, ample bar seating and counter space, and 2 televisions. Fourth, the pavilion adjoins a charming brick-lined casita for guests, fully appointed with a complete kitchen, living room, kitchen, full bath and dining nook. Finally, the pastoral grounds provide tranquility on every side: mature trees, grassy play areas, and one’s choice of outdoor seating areas in both shade and sun. Parking for residents and guests is easy: 2 garages house 4 cars, and the parking court accommodates more. This estate, though just 3-4 minutes to Lafayette’s shopping, restaurants and amenities, is a distinctive and rare retreat from the bustle and cares of the outside world.
