R. Andrew Garthwaite, AIA

Andrew grew up in the Upper Valley. He is a graduate of Haverford College and the Yale University School of Architecture.  After graduation, he worked in London for the classicist John Simpson and returned to the Upper Valley where he is now a partner in an active office enjoying a wide variety of clients and projects. He is licensed in New Hampshire and Vermont.

Andrew particularly values the buildings and landscape of New England and seeks to reinforce the sense of place in each design. Design decisions from site planning to detailing are related back to the character of the project’s context.  His approach to sustainable design has grown out of a long interest in climate responsive design and is integrated into all projects.

Andrew enjoys history, art and culture and particularly the local histories and material culture of New Hampshire and Vermont’s towns.

He discovered the pleasures of gardening from his parents and while living in Iran and England, and enjoys practicing the design and craft of gardening at home in Lebanon NH, at a community garden plot, leading a team at St Thomas in Hanover and in a garden of potted tropical plants on the office porch.

Andrew has been involved with many Upper Valley non-profits, serving on the boards of Opera North, Lebanon Opera House, Twin Pines Housing Trust, North Country Community Theatre and St Thomas Episcopal Church.  When not at the office, at a rehearsal or in the garden, he attends as many performing arts events as possible and enjoys the diversity of community arts organizations.
