Ethan P. Tirrell

Project Engineer

Ethan has been professionally active in the construction industry since 2006. He started out as a carpenter in high-end remodeling and renovation until 2010, when he kicked off his structural engineering career here at Structures Workshop. Ever since, Ethan has been an invested, thoughtful, hardworking, and significant contributor to the shape of Structures Workshop. His passion for engineering is rooted in an affinity for problem solving and a love for building. As a structural engineer, Ethan enjoys the collaborative nature of the design world and the active role design teams have in giving life to ideas.

Ethan is especially interested in residential construction, where attention to detail can shape a house into a home. In 2017, Ethan sharpened his skills and his attention to detail by both designing and building a house for himself in Rehoboth, MA, where he currently resides. When he is not building at his house, Ethan spends much of his time working out, playing sports, cutting down trees, hosting family-style dinners, or connecting with people. Ethan lives an active and engaged life, looking to be a “builder” in all that he does.
