Landmark Estates is a 62+ active-adult condominium community in Pelham located near the Windham border. The development contains 42 homesites and is designed around detached condominium residences surrounding a central clubhouse. Its relatively recent construction, low-maintenance orientation and southern New Hampshire location make it distinctive among Pelham's established residential communities.

Homes were constructed primarily from approximately 2020 through 2022, with multiple floor plans offering ranch and two-story configurations. The detached homes use contemporary New England residential styling, wood-frame construction, vinyl exteriors and shingle roofs. The neighborhood layout provides each residence with the character of an individual single-family home while common ownership of infrastructure and land simplifies exterior maintenance.

The central clubhouse serves as the community's primary shared amenity and gathering place. Residents also benefit from common open acreage, landscaped grounds, private roads and association-maintained exterior services. The development emphasizes a quiet, socially connected active-adult lifestyle rather than extensive recreational facilities, with the clubhouse providing space for gatherings and community activities.

Landmark Estates is positioned close to shopping and major commuting routes in southern Pelham and neighboring Hudson and Windham. Route 111A and nearby connections provide access to Route 3 and I-93, making Nashua, Manchester and northern Massachusetts practical destinations. The combination of newer detached homes, a central clubhouse and a 62+ age restriction creates a low-maintenance community geared toward active-adult residents.
