New Hampton Construction

New Hampton Construction is a third-generation residential and commercial construction company based in Centerport, New York, serving homeowners throughout Long Island. The company provides a full design-build approach, handling projects from initial planning and design through permitting, construction, and final completion. Its services include residential renovations, additions, new construction, commercial construction, and dedicated accessory dwelling unit (ADU) projects.

New Hampton Construction has a dedicated ADU service offering focused on creating private, comfortable, and fully integrated living spaces. Its ADU projects can be designed as age-in-place suites, adult children’s suites, guest houses, rental properties, home offices, wellness spaces, and pool houses. The company states that it handles the process from design and planning through permits, scheduling, vendor coordination, construction, and final inspection.

Because New Hampton Construction provides ADU design consultations, architectural coordination, planning, permitting, and construction, it is appropriately classified as both an ADU Builder and ADU Designer. I found no indication that it manufactures or sells standardized prefab/kit ADUs, so Prefab/Kit Provider should not be included.

ADU Design & Build Process

1. Vision & Design — Collaborative consultation to establish the homeowner’s goals, layout, aesthetic, and functional requirements.
2. Planning & Selections — Material and finish selections, detailed project planning, permitting, scheduling, and vendor coordination.
3. Build & Transform — Construction managed by a dedicated project team through completion and final walkthrough.

New Hampton Construction states that most ADU projects take approximately 4–8 months, depending on scope, permitting, and site conditions.
