Arco Homes

Arco Homes is a Newton design-build firm — the company says it has been designing and building for almost two decades — founded by Luis DiazGranados, who leads construction and design, and Carolina Trujillo de DiazGranados, who heads development. It works across Greater Boston's higher-end suburbs, from Wellesley and Dover to Cambridge and Brookline, with a self-described focus on custom, ground-up builds, large renovations and historic preservation. Reviews describe a full design-and-build process rather than just construction: one homeowner says ARCO took their wish list and turned it into a finished house, with Luis handling the design directly, in a review written two years after the house was completed. Another client, a real estate broker who works closely with the firm, describes it as architecturally innovative and focused on the quality of its finishes across the properties it presents for sale. A repeat client worked with ARCO twice — first on a downtown Boston office remodel, then investing in a Brookline home remodel for resale — and was satisfied both times. A 2022 review describes the firm delivering a project on time despite the early pandemic's supply and scheduling uncertainty. A serious complaint sits alongside that praise: a March 2022 one-star review accuses the company of not paying its bills and threatening people with government agencies after a job is finished. It's a specific, pointed allegation, unanswered by any visible reply, and worth asking about directly — particularly for anyone whose subcontractors or vendors would be paid by Arco rather than the homeowner. For a full custom build or a high-end renovation in the western suburbs, Arco's design-build model and repeat clients point to real experience — but given the one payment complaint, confirm payment terms for any trades or subcontractors involved before signing.
