Sometimes before I meet with a client, I have an inspirational moment which requires a quick sketch . You can say alot with a sketch- like this one- in spite of the fact that I've pasted the image backwards, it conveys a casual room arrangement. If the client imagines another possibility, I can quickly sketch it. This is the collaboration I enjoy the most. You talk, I sketch. Together we revise and get to the best solution for your lifestyle. I'm not sure how I could get through an entire week without sketching. It's relaxing, and it's useful. Sometimes I see a potential problem that I didn't consider in the floorplan. Think in 3D- it's how we experience the world around us!
