Firm Profile

Abacus Architects + Planners is an award winning full service design firm founded in 1989.

Our work has been featured in many publications, and has won prestigious design and public services awards


We serve public and private clients with innovative solutions to today’s design challenges. We are small enough that partners David Eisen and David Pollak work directly with clients on every job, and large enough to offer the range of expertise needed to follow through on planning and architectural projects. Our comprehensive approach emphasizes thoughtful design, cost-effective construction and sustainability. Much of our work focuses on rebuilding the integrity of urban environments, guiding our clients through the design, approval, funding, and construction process. We know how to listen and to lead, building a consensus around effective design proposals.

We believe that the best architecture grows out of a close relationship with both our clients and the context in which they are building – the city, landscape, nearby buildings, and the character, culture and history of the surrounding area. Design evolves as a resolution of both internal and external conditions, filtered through the insights of our professional colleagues and civic stakeholders. Our work ranges in scale from urban planning down to the intimate details that solve practical problems, while inspiring an appreciation of the world around us.

Abacus utilizes Building Information Modeling technology (BIM) on every project, developing a comprehensive data base that allows clear visualizations, accurate drawings and cost estimates, and efficient construction. BIM also facilitates an inclusive working methodology that brings our clients, consultants and the broader community into the design process, and facilitates the integration of sustainable design principals throughout our work.

We have had the opportunity to work with a range of terrific clients. They include prominent institutions, cities and towns throughout the region, for-profit and non-profit developers, business owners, and home owners across the country.
