About Us

Greenfield Architects Ltd. is a professional architectural firm founded in 1990 with the goal of providing clients with the highest quality architectural services. We are part of a family-owned business, The High Companies, that has operated in the community for more than 90 years. As one of the business units within High, Greenfield Architects evolved from a firm that primarily served the needs of The High Companies to a firm that currently performs more than 80% of its work for third-party clients.

With 33 years of experience, Greenfield Architects, Ltd provides a wide range of architecture, adaptive reuse, interior design, and planning services in the public and private sectors throughout the eastern United States for projects ranging from small renovations to large-scale developments.

We provide programming and feasibility studies to complete construction documentation to construction administration of the building contracts for multiple buildings types.

  • The portfolio of our project expertise allows us to serve Clients who have an eye for craftsmanship, or mass-production manufacturers or small bottom-line niche enterprises.
  • We create signature facilities for clients who operate complex arts and entertainment venues and for clients entrusted with large fiduciary responsibilities.
  • Clients with an old, antiquated facility ask us to reinvigorate it; for the odd ‘white elephant’ we help clients envision a better future through repurposing, buying a second life for an existing building.
  • Clients whose vocation is serving a greater Good or who train our young people or are growing their community outreach look to us.

Clients entrust their designs to us for all types of buildings. These include educational facilities, office buildings, commercial and public buildings, government and municipal buildings, hotels, manufacturing, industrial, and warehouse and distribution facilities.

We are committed to creating superior environments with each project, where people want to live, work, and play, while successfully achieving our clients' business goals and objectives. Greenfield Architects employs architectural creativity to maximize the function and aesthetics of the built environments, guided by our "Success by Design" philosophy.
