If you are considering modernizing, expanding or renovating a building, PSA is New Jersey’s preeminent architecture firm. We complete over 300 projects annually and over 98% of those projects are renovation, modernization or redevelopment projects. Working with existing buildings often requires a higher level of detail and coordination as the tolerances are often much smaller and latent problems are more likely. Because our experience with existing buildings is so extensive, the more complicated the project, the more value we bring to our clients. Our 35 years of experience and expertise with these types of projects is hard to match.
