About Us

Founded in 2002, partners Matt McCormack and Zack Gelfer pride themselves on professional construction management services with a distinctive set of 4 core competencies.



We're passionate about the values that make each project unique. The process begins with an internal approach where each site is evaluated. Not like a blank canvas, but of a existing portrait where the design and build elements are incorporated into a site's best qualities in order to achieve the optimal building potential.


We all hope to get more out of our lives, and for some, that means less commuting and more living. It means appreciating that sometimes less is more, a philosophy that embodies conscious and sustainable living. We build cool, functional, and boutique creative living communities in established urban centers for people who love the vibrant mix of city living.


We incorporate standardized selective green building practices into every project that afford comfort and true cost savings that will not take years to realize.


We value a team approach to the building process that includes joining client, architect, engineer, designer, and builder.

A Word from cobalt home owners


Tracey + Roger L.

"We loved using Cobalt Companies for our home remodel and addition that got us the home of our dreams. They were on-time and on-budget which is unheard of!! Their stellar design team provided guidance that helped bring the house together beautifully. We could not be happier working with them and highly recommend them.”

"I just wanted to take a minute and send you all a BIG THANK YOU note and let you know that we are very happy and excited in our new home. The house is beautiful, full of light and has a great serenity to it. You deliver something very positive to people in a very personable way, and we hope COBALT keeps carrying out this mission and grows into its full potential without losing its unique personal touch. Best wishes!"

"It goes without saying that working with Cobalt has been a great experience for us. We were able to stay on budget largely because Cobalt kept an eye on things so conscientiously, and because they handle the snags that come up in construction so effectively (and honorably). We are truly grateful for that."

"Working with Matt and Zack at Cobalt was an overwhelmingly positive experience. We would not hesitate to build another home with Cobalt!"
