Ternbury Square is a smaller condominium community in southern Nashua near Spit Brook Road and Route 3 Exit 1. Nashua's assessor database identifies the property legally as "TERNBURY SQUARE CONDO'S," confirming that this is a condominium rather than simply an apartment complex. Its location provides a suburban residential setting while remaining very close to the major southern Nashua commercial corridor.

The community dates to approximately 1980. Typical units are roughly 1,220 square feet, with two bedrooms and two baths, although layouts vary and some include finished lower-level space. Construction is generally wood frame with clapboard/vinyl siding, asphalt-shingle roofs and concrete foundations. Listings describe both garden-style one-level units and townhouse-like arrangements, with balconies/decks, basement storage and assigned parking, carports or garages.

HOA fees have risen over time, from approximately $325–$400 in older listings to about $465 in a current 2026 listing. Services documented across listings include landscaping, plowing, sewer, water and trash; common acreage and storage are also documented. There is no evidence of a large resort-style amenity package, so Ternbury's appeal is primarily its low-maintenance residential setting and location.

Ternbury Square is exceptionally convenient for commuters using Route 3 and for residents shopping in southern Nashua. Listings specifically mention proximity to Pheasant Lane Mall, Shaw's, restaurants, schools and parks. The development is assigned to the Nashua School District, with Sunset Heights School, Fairgrounds Middle School and Nashua High School South identified in recent listings.
