Expand Your Living Space with a Custom Basement Remodel

We help Portland homeowners transform their basements into functional extra living space.

Does Your Basement Have Any of These Problems?

  • Your basement is unfinished and has lots of potential, but very little functionality.
  • You rarely spend time in your basement because it is unwelcoming or unusable.
  • Instead of a basement, you have a crawl space that you want to expand.
  • The home was built before 1993, and the basement may not meet seismic code.
  • You need extra space to accommodate an aging relative or rental unit.
  • Your home needs space for a home gym, theater room, bar, or other specialty space.

One Of a Kind, Just Like You

We help homeowners just like you turn their unfinished or unwelcoming basements into a space where they can thrive.

The design-build process allows you to plan how you want your new basement to look and feel before moving into construction. You'll work with a professional design team to find custom solutions that not only satisfy your needs and fit your style but also meet your budget.
