SERVICES
Planning

Cascade Design Associates assists you with defining your goals, budget and schedule. We will arrange a free consultation to discuss your ideas. We will listen and talk about building codes, zoning requirements, design & construction ideas and estimate how much it will cost.

Design

When you are ready to proceed…we will prepare drawings and documents that define your project.  If necessary, we will come to your home and take detailed measurements of your existing conditions and collect other information required for your drawings.

Once your drawings are prepared we will get together and review the details to make sure you are getting what you want! Cascade Design will make changes as directed. Finally, …your plans will be completed to get required permits and accurate bids from contractors.
