With the aging baby boomer population and rising housing costs, many families are choosing to live together under one roof. This trend is not only a practical solution for families but also a way to strengthen bonds and share resources. However, accommodating multiple generations in a single home often requires creative solutions, such as home additions or Accessory Dwelling Units (ADUs).

## Testimonial
- [Stacy Quintin Parys](https://southcoastbuildingllc.com/testimonials/stacy-quintin-parys/): We purchased a new home from Southcoast Building (prebuilt, move in ready) and the quality, design and attention to detail was great. Even after the sale, they were very responsive with quick to remedy any minor issue we had. Even now, 2 years later, they continue to show excellent customer service!.
- [Zack Martin](https://southcoastbuildingllc.com/testimonials/zack-martin/): I highly recommend working with Southcoast Building LLC. Both Mike and Roy were both very attentive to my questions and even when i requested changes or additional work, they made it easy to alter the project scope. My project specifically was funded by FHA 203K which they were able to accommodate no problem. Thank you to both of you!

- [Jose Ferreira](https://southcoastbuildingllc.com/testimonials/jose-ferreira/): Had this company replace all the windows in my 4-unit investment property and they were great.
