“Preserving Nantucket’s Architectural Heritage”

First and foremost we want to thank all of our amazing clients without whom, none of this work would have been realized. Our gratitude extends also to the Nantucket Island community which has supported us since early days.

We  are Luke and Carrie Thornewill, a husband and wife team who founded Thornewill Design LLC in 1993.  Since that time we have completed over 700 projects, (big and small).

Our design solutions are inspired by the beauty of Nantucket Island.  Our work carefully merges architectural history, the landscape and seascape, local traditions and contemporary concepts with the unique lifestyles and personal taste of our clients. Our design emphasis is on efficiency of space, balance, beauty, functionality and proportion, as we strive to create diverse design solutions for Nantucket homeowners.

Our work focuses on full service residential design of new homes, and we welcome historic preservation and renovation projects as well. We have also happily completed numerous additions, barns, garage-studios, studios, cottages and second dwellings, pools, pool cabanas, site master planning, feasibility studies, general landscape spatial concept drawings.

Our knowledge and expertise of the local home building process, regulations and requirements have been helping families build homes on Nantucket for over 25 years.

We offer customized services tailored to each specific client’s needs, ranging from preliminary feasibility studies and  basic permitting, to comprehensive custom design/construction document sets and complete project management.

We are as happy to work on a small project as a big one. A primary goal of ours is to make the design process an enjoyable and exciting experience for you!

We love what we do, and would love to work with you.
