Custom ADU Builder Serving Southeastern Massachusetts
BuildX is a premier ADU builder serving Southeastern Massachusetts, including the South Shore and Greater Boston area. With over 40 years of home building experience and a track record spanning more than $450 million in local projects, BuildX has established itself as one of the most trusted accessory dwelling unit builders in the region. Founded in 1985 and led by Buz Artiano, the company brings decades of hands-on expertise to every project.
Unlike many contractors who rely on prefab or modular construction, BuildX takes a different approach. Every ADU they build is custom stick-built on the client's property by their own crews — no prefab, no modular units, no shipping containers. Real construction by real craftsmen, from the ground up.
BuildX handles everything from permits to paint, delivering a fully finished accessory dwelling unit complete with kitchen, bath, flooring, and fixtures — move-in ready from day one. Their deep familiarity with Massachusetts building codes and local zoning regulations means they can navigate the regulatory process efficiently on behalf of homeowners.
What BuildX Offers as an ADU Contractor
As a full-service ADU contractor, BuildX manages the entire process from initial consultation through completed construction. Their process is designed to give homeowners clarity and confidence before committing to anything:
- Clear, realistic cost ranges provided early in the process — no hidden fees or surprise charges
- Guidance through zoning requirements and the permitting process
- Custom design tailored to the homeowner's property and family needs
- A 100-day build guarantee from the day construction begins
- Regular communication, respectful crews, and clean job sites throughout the build
Their ADU designs are built with multigenerational living in mind — ideal for aging parents, adult children, or extended family members who want privacy while staying close. Every unit is also designed with universal accessibility features, including wider doorways, step-free entries, lever-style hardware, and walk-in showers, making them suitable for residents of all ages and abilities.
BuildX offers several floor plan options, all of which are fully customizable. Current models include:
- The Haven — 900 sq. ft., 2 bed / 1 bath, covered entryway, starting around $335,478
