Bath and closet addition to Beaverdale home, review.
Des Moines

We had a bath and closet addition added to our Beaverdale home. We weren't sure how it would turn out since the age of most Beaverdale homes are very old. We met Kelly and started the conversation. Later met with Nicholas and then Julieta and the project started. All the crews on site were great to work with. Everyone was very responsive. The end result was far above expectations. Zenith did not cut any corners and did far above-average work. I was hesitant on some of the design features but once they fell into place was absolutely more than impressed. Zenith is a superior design and build company so if you are looking to have it done right make sure to contact them.

FAQ About Home Additions

How much does an addition cost in Iowa?

The cost of an addition is dependent on many factors — the size, the materials, and what you’re putting inside of it!

Is a home addition worth it?

At the end of the day, it depends on your goal and your budget. If you’re looking for more space to make your home into your forever home, probably! If you are building an addition before listing your home for sale, it might not be! But that’s where our expertise comes in.

How long does it take to build an addition on a house?

The construction for an addition takes anywhere from 10-16 weeks to complete depending on the scope of the project and what is being added.

How do I start an addition to my house?

You start by contacting us! We can come out to your home and take a look at your existing space, talk about what you’re looking to add, and provide you with an initial estimate
