4 Sunnyside Ave, Carnegie, PA 15106

Tucked at the end of a quiet Collier Township street on just over an acre of private, wooded ground, this custom stone-front ranch delivers true one-level living plus a walk-out lower level built for entertaining. A circular drive and wraparound covered porch set the tone before you step through the arched wood door into a wide tiled foyer. The open main level is finished the way custom homes should be — crown molding throughout, and a great room anchored by a gas fireplace framed in arched built-ins and a wall of windows overlooking the trees. The kitchen is the working heart of the plan: full-height glazed cabinetry, stone counters, stainless appliances with gas cooking, tile backsplash, a prep island with second sink, and a peninsula bar seating four. The adjoining dining area opens through sliders to the covered rear patio. The owner's suite sits in its own wing with a vaulted ceiling, walk-in closet with built-in shelving, and a spa bath with double stone vanity, corner soaking tub, and glass shower. Two other main-level bedrooms, full hall bath, and a generous first-floor laundry off the oversized two-car garage complete the main floor. The finished walk-out lower level is the showstopper — a custom wet bar seating six, a second gas fireplace, an expansive gathering area, a full bath, and a private bonus room that works as a home gym, office, or guest quarters. Its own exterior entry makes hosting effortless, and the space nearly doubles the home's living area. Outside, the covered patio with ceiling fans and outdoor speakers overlooks manicured landscaped beds and a mature tree line — total privacy. The full 1.01-acre parcel includes the wooded strip to the right of the home. Minutes to I-79 and the Parkway West, Robinson Town Centre, and roughly 15 minutes to downtown Pittsburgh, with Settler's Cabin Park and the Montour Trail close by. Chartiers Valley School District. Space, privacy, and quality — all on one floor!
