NESEA Business Member Directory

We believe in designing buildings with purpose and beauty, sustainability, and suitability for the communities using them and the environment we share. Sustainability has been a focus since our firm was founded in 1996 and is integral to our practice at every phase of design and construction. Sustainability is interwoven into all aspects of our work from reviewing siting, massing, and building systems at the conceptual phase to carefully specifying materials with low embodied carbon. As a signatory to the AIA 2030 Commitment since 2018, we strive for all projects to be carbon-neutral by 2030. We are proud to be among the 27 nationwide firms (15% of participating) that met the 70% energy reduction target for 2019.

Hi. We're Juniper Design + Build. We create really special homes: beautiful, sustainable, and indelibly yours. We're majority women-owned and based in Portland, Maine. We collaborate with you to craft a home that reflects your unique vision, is easy to live in, and is so beautiful it just makes you happy. Great design is baked right into our company DNA: our AIA award-winning Design Director is a co-founder of the firm. Reducing carbon footprint is a big priority, from maximizing energy efficiency to using low-carbon materials. It also means we sweat the details that make houses last longer. We're constructing an environmental legacy we're proud of.
