Steeped in Portsmouth history, the renowned Sise-Laighton House is an extraordinary early 19th century residence that reflects more than two centuries of architectural heritage. Built circa 1806 and long associated with two of Portsmouth's most distinguished families, the home has been thoughtfully preserved while honoring its remarkable character. Ideally situated on renowned Richards Avenue in Portsmouth's coveted Little Harbour School District, the property enjoys one of the city's most desirable residential settings. A short stroll leads to downtown Portsmouth's acclaimed restaurants, boutiques, the waterfront, Prescott Park, the Farmers' Market, and nearby city athletic fields. Beautifully designed gardens and a private rear outdoor terrace create an exceptional setting for outdoor entertaining and peaceful evenings at home, including a memorable vantage point for summer fireworks over Leary Field. Rich in history, distinguished in design, and exceptional in location, this beautiful home and grounds represent a rare opportunity to own one of Portsmouth's most incredible residences.
