Ahlgren and Son Builders

This Sanbornton, NH Addition was designed by Pam Barter.  As the general contractors for the construction, we removed the condemned building and replaced it with this modern addition.


Our specialties include warm, livable, new spaces, and minimally invasive period and structural restoration of antique houses and barns.

Call on our knowledge and innovation for your next building project, large or small.

You’ll be glad you invited Ahlgren and Son Builders into your home. ¬†Building contractor choices abound and we are proud to stand out for our positive and respectful attitude, our attention to detail, and our enduring works.
