Naplex Construction LLC is a small, Lexington, Massachusetts custom home builder and developer run by Mary Beth Busa (M.B. Busa), whose own listing centers on new home construction and custom home development, including retrofitting houses for single-floor, aging-in-place living. Every review on Houzz tells a similar story: buyers who paid well into seven figures for a Naplex-built home describe an experience built on trust that carried through the purchase and into the first year of living there. One client working with Busa on a renovation said the quality of the materials and interior details exceeded expectations, and a flooring subcontractor who has worked with the company for more than ten years singles out its attention to detail on every part of the houses it builds. Another set of buyers called the Busas helpful before and after the sale, following up on questions and small corrections after move-in. The written record is strong but dated — every review on file runs from 2014 to 2017, and all seven ratings live on Houzz alone, so there's no recent, independently sourced read on current pricing, availability, or workload. For a homeowner planning a custom build or a full home renovation in the Lexington area, the historical record here is a genuinely good sign; just confirm current availability and ask to see a more recent project before committing.

My husband and I purchased a new, $1M+ family home developed and built by Naplex Construction LLC (M.B. Busa). Home is located in Lexington, MA. Throughout the home purchase period and the first year of living in this new home, we had only an overwhelming positive experience with M.B. Busa, her team, her company. What transpires through our interactions, from the beginning, is trust: trust until the purchase deal got completed, and, perhaps even more importantly, trust after completion of the deal, as we now live in this beautiful new home. Under this umbrella of "trust" comes everything else: super fast responsiveness and presence from M.B. Busa and her associates (not just leading into the home purchase, but also after it, while we settle in the new home during the first year); absolute fairness in price negotiations; use of high-quality materials and craftmanship (eg, moulding, hardwood floors, cabinetry, windows, appliances, AC / heating / water hardware systems, etc); no compromise on quality, even under rushed timelines. Overall, a genuine "family" feeling: Naplex Construction is a family-run business, we are now family here in Lexington, and the work and interactions have been run in that spirit.
Our experience working with Naplex and the manager Mary Beth is so pleasant and we wish we could have another home for them to renovate. The quality of the building, the material, and the details of the whole interior have exceeded our expectation. We are so happy that we have worked with them and we would highly recommend anyone who is thinking about renovation, update or even a complete rebuild to give Mary Beth a call. She is wonderful to work with and you will love her and her crew!
I'm a subcontractor that responsible for new wood flooring for Naplex Construction. I have been working with Naplex for more than ten years. To me they are one of the best custom home builders out of Lexington Massachusetts. I'm very impress particularly the attention to details on all aspects of the house that they built. Not only they're using quality materials but also have the highest quality workmanship on every field from exterior to interior. Helping Naplex's houses look best is like helping myself . Thank you for helping my company stays busy throughout the years.
The Busas were great and our house is lovely. The arts and crafts small detailing made the house feel unique and the layout works very well. The Busas were helpful before and after to respond to questions and corrections. Thank you!
We love our house built by Naplex Construction. The layout of the house is practical, the finishes are of good quality without breaking the bank, and the design choices are neutral and really offer a blank slate that you can do so much with. Everyone who visits our house compliments the craftsmanship and finishes (and asks if we picked out the paint colors... no we didn't, but we are so happy with them). We relocated from the west coast and were first time homebuyers, so we had a ton of questions--everything from how to properly winterize the house to identifying local contacts to help us keep up the property. Mary Beth was extremely helpful and cooperative with all of our questions from before we closed on the house until after our one-year builder's warranty expired; she is very detail oriented and is fantastic at following up both with subcontractors who are sometimes hard to pin down and with new homeowners who are overwhelmed by all the work involved in the upkeep of their new home! The Naplex team are consummate professionals -- they are proud of their work and they stand behind what they do.... an absolute pleasure to work with.
