Design-Build Home Additions

A seamless home addition process

Your home is in the right place, you just need a little (or a lot) more of it. Whether you are looking to add a mother-in-law suite to accommodate multi-generational living, or you want to finish out an existing space like a basement or an attic, you can count on Merrick to be the trusted professional who will protect your home and space. Using our meticulous design-build process, we work with you from the initial design development, walk through the permitting process, and oversee every step of the building construction. We take pride in making your addition look like it was always part of your home.

An Architectural Approach

Our skilled designers and distinguished craftsmen take pride in designing and building your addition. Their detail-oriented commitment to your project results in a space that is indistinguishable from your original home. From early design concepts to final finished space, you can trust that Merrick will protect your home and family throughout the home addition process.

Planning your home addition

When building a home addition there are two key considerations that come into play. First, carefully evaluate the available space for hidden potential and ensure the new addition seamlessly integrates with the existing structure. Secondly, setting a realistic budget and conducting thorough cost estimates helps determine the scope of the project and the materials that can be utilized.

Merrick built an addition at our house. My wife and I needed more space for a growing family and we didn't want to leave our neighborhood. We are truly thrilled with the work Merrick did. Our house is everything we wanted and more.
