A House Addition Can Take More Than One Form

Sometimes, a simple “bump out” to your existing kitchen or bath is enough to give you that valuable added space. Other times, building a room or maybe a garage add-on is the answer.

On a smaller lot, consider building up – a full or partial second story addition with a bedroom or bath.

As your local, award-winning home addition contractors, we’re here to help you weigh all the options, share ideas, and co-create your house addition.

We were given a timeline and they beat it!

Demolished, enlarged, and completely remodeled our kitchen. Huge project. We were given a timeline and they beat it. 14 Weeks. They were there everyday except one. (I was grateful for the peace.) Their computer program, Co-construct, allowed instant communication and a complete record of communications. Their designer was invaluable. The workers were competent, skilled, kind, respectful, happy, clean, and cleaned up their mess as they went. They considered our every concern, were always available, and I consider their whole team partners in our happy home. I cannot say enough good things about MSK Design Build.
