Perched on a hill in a small association along the South Mill Pond, this spacious South End home just blocks to downtown Portsmouth and all 3 schools! Blending 18th-century charm with modern flair, this hip-roof Colonial offers historic character with contemporary conveniences. Designed for both entertaining and everyday living, the recently renovated kitchen features Caesarstone countertops, Thermador double wall ovens (one steam), a gas burner with hood, a stainless-steel farm sink, and two pantries. High ceilings, a bay window with a custom window seat, historic fireplaces with gas inserts, and abundant natural light enhance the formal living and dining rooms. Unwind in the air-conditioned family room, which opens to a charming brick patio and a secluded garden with a grape arbor, mature perennials, and a lush lawn, fully fenced in a dog friendly association —perfect for summer gatherings. A first-floor guest suite with an en-suite bath double as a home office. With finished and unfinished basement spaces, plus an attic, there is an abundance of storage, flex spaces and expansion potential. Deeded off-street parking for two-plus guests spots makes this free-standing condo feel like a single-family home. Enjoy summer meals on the spacious 2nd story deck just off the dining room with glimpses of the Piscataqua River at the end of the street. Showings begin at Open Houses Friday, 3/14 4-6pm and Sat. 3/15 12 -2pm.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
