We were looking to take down a wall that divided a basement. The project, structurally complex, required installing a 22 foot beam across the length of the ceiling. Keith was great at explaining what would be involved in the initial project, as well explaining necessary changes when unexpected matters arose once we got inside the walls.

Our approach

Truly integrated design-build for a seamless basement remodeling service

Before we begin construction on your basement renovation, we will work together to:

  • Design and layout the space to fit your needs and lifestyle as well as the structure of your home.
  • Develop construction plans that include all the required permits, systems, trades, and finish carpentry details needed for your basement remodel project.
  • Help you make material selections for cabinetry, flooring, tiles, countertops, fixtures, glass, amenities, and more.
  • Agree upon a budget that is realistic for your project and anticipates any potential surprises or roadblocks, which is especially important when remodeling older homes.

Let's work together.

If you have a vision, we’re ready to help you realize it.
