We make spaces for people.

We build unique projects for uncommon clients.

Our work includes commercial and retail spaces, community gathering places, custom residences, urban infrastructure, public art, and regenerative gardens.

We appreciate the complex, savor the strange, and celebrate the exceptional. We think every project deserves to be extraordinary.

We find joy in working together.

We embrace a collaborative approach that erodes preconceptions and nurtures the joy of discovery. Our process is designed to inspire the curiosity of our clients and ourselves.

We share delight in the discovery of the unexpected.

We merge inside and outside.

Every project is set within a mix of needs, context, social dynamics, and environment. Our expertise, which bridges Architecture, Landscape, and Urban Design, recognizes and works within these forces.

Based in Worcester, Massachusetts, with projects throughout New England, OPRCH works directly with communities, mission-driven organizations, and creative entities, integrating cultural identity into the design of public and private spaces.

We believe design adds value to our lives, our homes, our cities, and our world.
