443 Walnut Street

Sewickley, PA 15143

A truly one-of-one residence in the heart of Sewickley Village. Completely reimagined in 2025, 443 Walnut combines the scale and privacy of a custom luxury home with the ease and walkability of an urban penthouse lifestyle—crowned by an extraordinary approximately 1,100-square-foot rooftop living level with panoramic 360-degree views. A private street-level residential entrance opens to your own elevator, serving all five levels from the basement to the rooftop. The second and third floors are devoted entirely to the residence, with approximately 3,668 square feet of living space, three ensuite bedrooms, dramatic entertaining areas, soaring ceilings and exceptional custom finishes. The rooftop is far more than a typical deck. Served directly by the elevator and complete with its own powder room, this expansive private outdoor level offers substantial space for dining, lounging and entertaining. Its scale and panoramic views create an outdoor living experience rarely found anywhere in Sewickley and extend the home well beyond its stated interior square footage. Enjoy whole-building ownership, generous indoor and outdoor living, privacy and elevator access without the acreage or HOA—all just steps from Sewickley Village restaurants, cafés and shops. Approximately 1,000 square feet of separately accessed ground-floor commercial space is currently leased, offering the rare combination of a private luxury residence and recurring rental income. The commercial space is fully separate from the residence. Lease and income details are available to qualified buyers upon request. Additional lower-level space provides substantial storage, a full bathroom and flexible bonus space beyond the stated residential square footage. For added convenience, the seller will provide two nearby leased parking spaces for a minimum of two years following closing. Downsize the maintenance, not the lifestyle.
