Architecture, design, construction, and solar—seamlessly integrated, thoughtfully implemented, with lasting impact. We listen carefully, think ahead, and stay with you from first spark to final details.
We'll help you reveal possibilities, make confident decisions, and ensure the process feels as good as the outcome. You set the direction and we'll get you there—beautifully.
For 50 years, we’ve been designing and building the world we want to live in—shaped by lasting relationships, shared prosperity, deep environmental care and long-term thinking.
We believe businesses have an obligation to positively impact the world around them. Our focus starts at home on Martha’s Vineyard and ripples out to people and places far beyond. Our values don’t sit on a shelf. They shape every decision we make, on every project, every day.
South Mountain’s mission is to uplift our community and environment by designing and building for a just future.
For more than 50 years, our work has been guided by a simple principle: care for people and place, build lasting relationships, and trust that shared ownership and equity make us stronger. We believe in using our voice to promote those values—on Martha’s Vineyard and beyond.
Locally, we bring them to life through architecture, construction, and solar—collaborating with clients to create enduring places with meaning and purpose,
rooted in a shared commitment to something more.
