Why Build an Addition?
To get more space!
Older Portland homes are lovely but may not accommodate a growing family, in-laws, or hobbies.
Build out or build up and increase your livable space.

Financing and ROI
- Our team guides you through the financing process to find the best funding solution for your addition.
- Adding on is often more cost-effective than moving and allows you to keep your existing interest rate.
- Your family experiences immediate return on investment from day one, transforming cramped quarters into comfortable living space and finally enjoying your home instead of feeling confined by it.
