Timberbrook builds home additions in central Iowa that are designed to match and complement your existing structure. Whether you need an extra bedroom, a larger kitchen, a sunroom, or a full second story, we approach additions the same way we approach new builds — with careful planning upfront and quality construction throughout. We'll walk the property with you, understand how you use your space, and build something that feels intentional, not like an afterthought. Additions are priced by project after a site visit and written estimate.
