We design ADUs that feel private, comfortable, and fully integrated with your property, without sacrificing the feel of your main home.
Adding an accessory dwelling unit is more than just building a second structure—it’s about creating independence, flexibility, and long-term value on your own property. Whether it’s a private suite for a parent, space for an adult child, or a beautifully designed rental, we build ADUs that feel complete, connected, and truly livable—without disrupting your main home.
Give aging parents a private, comfortable space close to family, with their own kitchen, bathroom, and entrance.
Support college grads or young adults with an independent living space as they transition into the next stage of life.

Whether it’s a place to change, host guests, or unwind between swims, we design pool houses that feel like a natural extension of your home.

Get the focus and separation you need with a quiet, detached workspace for calls, clients, or creative work.

“We wanted to keep my mom close as she got older, but we also wanted her to have her own space and independence. New Hampton Construction built a beautiful accessory dwelling unit right in our backyard. They thought of everything, from accessibility to privacy, and made a stressful situation feel completely manageable. It’s brought our family so much peace of mind.”
