Overview

The Pickering-Heffenger House dates to c.1804 and features quadruple crown moldings, marble fireplace mantels, soaring ceilings, and extraordinary millwork. The home has been thoughtfully modernized with a granite kitchen and wide-board cherry floors, and it offers six bedrooms with six renovated bathrooms that blend historic character with modern comfort.

The original carriage house and stable have been transformed into three separate residences, consisting of two one-bedroom apartments and one two-bedroom apartment. An existing inn license is also on file, creating additional operating options subject to required approvals.

Located along tree-lined Austin Street and just steps from downtown Portsmouth, the property can serve multiple living or rental arrangements while preserving a landmark setting. With its combination of a main residence and detached apartment-style units, it may fit buyers looking for a multi-generational layout, guest or staff accommodations, or a flexible hospitality use, subject to compliance with applicable requirements.
