About this House

Welcome to 149 Seneca Pl, in Venango Trails, a Colonial-style Heartland Homes Olsen model offering 4,638 square feet of luxury living with 6 bedrooms, 5 full baths, and a flexible 7th room for a 2nd office or music room. A grand two-story foyer opens to an expansive main level adorned with rich colored hardwood flooring and elegant arched doorways. Just off the entry, a bright study with crown molding and double French doors provides an ideal home office. Beyond, a stunning coffered ceiling with striking four-by-four grid detailing and crown molding crowns a formal room finished with a beautiful chandelier, currently used by the owners as a formal living room and equally suited as formal dining, a truly versatile space. The soaring family room is anchored by a gas fireplace, a ceiling-mounted sound system, and walls of windows that flood the home with natural light, flowing seamlessly into a gourmet chef's kitchen featuring a large center island with granite countertops, rich coffee-colored cabinetry, high-end stainless steel appliances, custom vent hood, gas cooktop, double ovens, soft-close cabinetry, and a walk-in pantry. An extended butler's buffet with upgraded glass-front niche cabinetry doubles beautifully as a coffee bar. The sun-filled breakfast area, currently used by the owners as their dining space, enjoys open sightlines throughout the main level, and French doors step out to the backyard. The main level also offers an exclusive guest bedroom with attached full bath, a rare and valuable feature, plus a spacious mud room off the garage with oversized closet. Upstairs, the expansive owner's suite is a private retreat with a tray ceiling, ceiling fan, and generous windows overlooking the serene wooded backyard, complemented by a spa-like bath with dual sinks, granite countertops, an upgraded ceramic tiled shower, ceramic tile flooring, and three custom closets including his-and-hers walk-ins. The second and third bedrooms share a full bath with dual sinks, granite countertops, and coffee-colored cabinetry, while the fourth bedroom enjoys its own attached full bath. All bedrooms include closets and lighted ceiling fans, and every bath features granite counters and ceramic tile flooring. The bedroom-level laundry room is a genuine upgrade with a window, utility sink, built-in cabinetry, and ceramic tile. The finished lower level is built for entertaining and prewired for a surround sound system, featuring built-in media cabinetry on the wall, versatile theater space, a pool table and game area, a full bath, a sixth bedroom currently used as a home gym, a flexible seventh room perfect as a gym, music room, or second office, and generous finished storage beneath the stairs. Step out through French doors from the breakfast area onto an expansive custom stamped-concrete patio, ideal for al fresco dining and evening gatherings, overlooking a flat, private, low-maintenance, resort-style backyard where the serenity of the wooded setting is one of the home's best features. A playground set is included, with ample space for vegetable gardens around the house, and plenty of room for your dream swimming pool in the backyard. A three-car attached garage with built-in shelving and an oversized driveway complete the package. Venango Trails residents enjoy a community swimming pool, clubhouse, gym, playground, walking trails, and lake. Minutes to Costco and Target in Cranberry, Route 19 shopping and dining in Wexford and Cranberry, with quick access to I-79, I-279, and the PA Turnpike, an easy drive to downtown Pittsburgh, and roughly 35 miles to Pittsburgh International Airport. Served by Marshall Elementary School and Marshall Middle School in the North Allegheny School District. Seller disclosure to be uploaded July 18th.
