Whether you're upgrading an existing structure or building from the ground up, Peter T. Erdelyi & Associates, Inc has the expertise to oversee your project through completion.

Our team of professional engineers, drafters, expeditors and project staff will deliver plans that withstand the test of time.
"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

Arcelab, Inc. / Architects
Arcelab, Inc. / Architects
Arcelab Inc. Architects is guided by Bill Gregory, AIA with 50 years of education and experience in architecture. We focus on residential design and work in contemporary and some traditional (Spanish, Craftsman, Cape Cod) styles. We start with the client's program/budget goals combined with the opportunities/constraints of the site and develop a building design that brings them together in a cohesive solution. Bill will focus Arcelab's team on achieving your goals. We will be creating an environment that will be the center and starting point of everyday of your life and which will be the background of the many family events and memories still to come. While all examples of architecture are buildings, not all buildings are examples of architecture. The difference between a building and architecture is the informed care that went into the design of the building - including proportions, sequence of space, volume and light, relationship to site, material selection, and the details.
"We couldn't have hired a better architect. Bill worked with us closely, all the way through construction. He was creative, knowledgeable, thorough and meticulous. He was a pleasure to work with."
