The building hired Zimmerman for a size-able basement renovation/repair project. This was a while ago now, but my recollection is that the design/documentation process went relatively well, but the construction administration phase was not well handled by Zimmerman. We have since engaged a different firm for a larger two phase exterior renovation project.

I've used Howard L Zimmerman Architects over the last 10 years about 25 to 30 times. I could not recommend them struggling enough. If you decide to use them call Richard Moses at their firm. He is the front person and I guarantee you'll like him immediately.

I'd recommend them highly. I am on the board of our co-op and they've done several jobs for us. The work has always been very high quality and--more or less--on budget. They are very professional, smart people.

Zimmerman did a fine job - very professional, but very happy to bill for every possible minute. If you're willing to pay, they were very thorough and professional.

We used Howard Zimmerman's office and I was quite pleased. However, the reason why our job went so smoothly and was sucha success was due to the individual who worked for Howard Zimmerman's office that oversaw our work. His name is Craig Jirak and hehas since moved onto another firm called Spar Unlimited. I was so pleased with working with him that when the time came todo more work in our building I contacted Craig at his new firm.I know if you have him oversee your project you will be very pleased as well.

Zimmerman architects have been amazing to deal with. First and foremost they are very knowledgeable -they seem to have seen it all and have functional working knowledge of most building related issues.
They are also easy to work with and very responsive.
