Additions

Expand Your Space with Our Home Additions

Maybe you dream about that kitchen with a large island that includes a prep sink and seating, Miele appliances, and two pantries. Or, a master bathroom with a double vanity and soaking tub and a living space big enough for the whole family to relax and put up their feet. Or, perhaps that garage for all of your projects?

With a home addition, we can transform the home you already love into the home of your dreams, with a new kitchen, master suite, living space, or even a new story.

If you’re in Walnut Creek, Danville, Alamo, Lafayette, or the surrounding area, chances are you love your neighborhood, school district, community, and location. Perhaps you were considering a move when it felt like your home was getting smaller every day. The home you’re in really can be the home you need, if you work with the right contractor to ensure your room addition, garage addition, or full second story addition is perfectly suited to your family and needs.

At MSK Design Build, we have the expertise and experience to help guide you through the process of adding a room or rooms to your house. A house extension is more than just an expanded space. It’s an opportunity to improve the function and flow of your home, all while seamlessly and beautifully blending the old with the new.

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.
