Residential Construction

DeCosta Construction has been building homes in Central New Hampshire for over 30 years.  Our reputation and professional manner precedes us as a quality, honest, home builder, and we are proud of it.We build all kinds of homes, though we do specialize in building with Insulated Concrete Forms and Manufactured Homes.  Because we are tradesmen at heart, we bring a skillset to the homesite that results in nothing shy of high quality.

We also focus on energy efficiency with our new home construction, which is why we have all the credentials to build you a true Energy Star home.

We are able to work with your budget to bring you the sort of residence that you deserve, and we don’t rate homes on how expensive they are to build.  We rate them on the quality of the craftmanship and the satisfaction of their owners.
