## Description

### Agent Description
Welcome to this exceptional opportunity combining space, flexibility, and a prime Upper St. Clair location. Enhanced by a newer contemporary-style second-floor addition, the home offers an expanded, functional layout designed for modern living. Set on a nicely usable lot along a quiet residential street, it delivers both comfort and lifestyle appeal.

The main level is filled with natural light, highlighting hardwood floors and a comfortable living room anchored by a classic wood-burning fireplace. The layout flows easily into the dining area and updated kitchen, creating a connected space ideal for both daily living and entertaining. From here, step directly onto the patio for effortless indoor and outdoor enjoyment.

A rare and valuable feature of this home is the main-level bedroom with a private ensuite full bath, complemented by an additional hallway full bath on the same floor—providing convenience and flexibility for guests or extended stays. An additional room on this level offers versatility as a home office, den, or additional bedroom.

Upstairs, the primary suite offers a true retreat with vaulted ceilings, recessed lighting, a private deck, and a separate dressing room. The spacious ensuite bath includes dual vanities, tile flooring, a whirlpool tub, a separate shower, and multiple skylights that bring in abundant natural light. Two additional generously sized bedrooms, a full hall bath, and a conveniently located second-floor laundry room complete the upper level.

The finished lower level expands the living space with a large game or media room featuring a second fireplace, an updated full bath, and flexible open areas that can adapt to a variety of needs.

The backyard offers a level, usable setting with endless possibilities, ideal for outdoor seating, gardening, recreation, or simply enjoying open green space. A fenced section adds additional functionality, and the direct access from the dining area to the patio enhances the home’s indoor-outdoor flow.

Additional highlights include an extended driveway with ample parking and a 2 car attached garage.

Conveniently located near shopping, dining, parks, and major routes, this home offers both accessibility and a peaceful residential setting.

Homes offering this combination of layout, space, and location are in high demand—schedule your showing early and submit your best offer.
