About this home

GRAND CAPE — Poised atop a private ½-acre lot at the end of a cul-de-sac, this custom-designed home offers an extraordinary combination of craftsmanship & privacy. Only 8 years young, it feels virtually brand new, with premium materials, custom millwork & commercial-grade systems throughout. The gracious first floor features a two-story foyer, elegant formal dining area, expansive kitchen w/ breakfast bar, eat-in area & Sub-Zero & Wolf appliances, plus a primary suite. At the heart of the home, a stunning great room w/ beverage fridge, bar sink & gas fireplace is highlighted by sliders & walls of windows overlooking the beautiful outdoor setting. The second floor boasts three additional bedrooms including a second primary suite. Ideally separated from the main living area, a private in-law suite, finished to the same exacting standards, provides an ideal retreat for guests or extended family. The finished lower level offers a gym, office, playroom, full bath & media room. Outside, professionally landscaped grounds surround a substantial bluestone patio w/ built-in gas grill, fireplace & outdoor TV. Beneath it all are state-of-the-art electrical & HVAC systems, superior insulation & high-performance infrastructure designed for efficiency, durability & long-term performance. A rare opportunity to own a home built to a standard seldom found in today’s construction, combining enduring craftsmanship with effortless modern living.
