What Longfellow Design Build does
Longfellow Design Build is a private residential design-build firm founded by Mark Bogosian in 2012 in Falmouth, Massachusetts and now operating across four regional geographies: Greater Boston, Cape Cod, Lincoln (New Hampshire), and Captiva Island (Southwest Florida). The firm delivers custom homes, additions, historic restorations, and ground-up developments under an integrated model where in-house architects, structural engineers, civil engineers, interior designers, and construction managers share a single contract and a single set of drawings from schematic design through final walkthrough. Core services are organized into Architecture & Design, Construction, and Engineering, supplemented by an Interior Design Studio (with furniture procurement across brands like Bassett, Arteriors, and Hubbardton Forge) and a Smart Home & Lifestyle Technology layer built around Lutron automation and Hunter Douglas shading.
