Custom ADU Builder Serving Southeastern Massachusetts
BuildX is a premier ADU contractor and custom home builder serving the South Shore and Greater Boston area of Massachusetts. With over 40 years of hands-on 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. Led by Buz Artiano, their team brings decades of expertise to every project, with a deep understanding of Massachusetts building codes, zoning regulations, and permitting processes.
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 panels, no modular units, no shipping containers. This commitment to real craftsmanship means homeowners receive a finished product that looks and feels like a natural extension of their existing property.

Their floor plans are purpose-built for families who want to keep aging parents or adult children close while maintaining privacy and independence. Universal design principles are incorporated into every build — including wider doorways, step-free entries, lever-style hardware, and walk-in showers — making their homes accessible and comfortable for residents of all ages and abilities.

Experienced ADU Contractors with a Proven Process
BuildX has been building custom homes in Massachusetts since 1985, serving over 6,800 families across the region. As a detached ADU builder, they understand that building an accessory dwelling unit is a significant decision — and they approach every project with transparency and respect for the homeowner's daily life.
Their process is designed to give homeowners clarity before committing to anything. Early in the process, they provide realistic cost ranges, guidance through zoning and permitting, and honest assessments of what is actually possible on a given property. Construction is managed with regular communication, a respectful crew, and a clean job site throughout.
For those who want to experience a completed ADU in person before making a decision, BuildX hosts live home tours at a recently completed 610 sq. ft. accessory dwelling unit located in Plymouth, MA. The tours run on Saturdays and Sundays from 11:00 AM to 1:00 PM, beginning March 7, 2026, and are free to attend with no sales pressure involved.
BuildX also produces The BuildX ADU Podcast, where host Buz Artiano speaks with industry experts about ADU construction, building science, zoning, septic systems, and everything homeowners need to know before breaking ground in Massachusetts.
For homeowners in Southeastern Massachusetts considering an accessory dwelling unit, BuildX represents a well-established, experienced, and transparent choice backed by four decades of proven results.
