What a Lakes Region lot changes

Wolfeboro, Ossipee, Alton, and Laconia are NH Lakes Region towns on the service-area list. The excavation and the septic are priced with the building rather than quoted separately afterwards, which matters more here than it does inland: on a lake lot the septic design is usually the thing that decides what will fit.

The published catalogue

Ten turn-key models, $147,000–$388,000:

  • The Bean - 384 sq ft - $147,000
  • The Wakefield - 525 sq ft - $216,000
  • The Newfield - 600 sq ft - $196,000
  • The Summit - 654 sq ft - $235,000

Shoreland and septic

Lake lots are a setback, shoreland, and septic conversation before anyone picks a model. We read the ordinance on the land consult.
