Interior Design Renderings, Process

Clients usually ask about the working process. Typically I work in my own home office, but here are two pencil drawings produced in my client’s office— two views of the a master bathroom for a project in Aspen. 
Following each rendering, you can see the preliminary sketch, created in pencil, red pencil, sharpie marker, and white-out. 

My client had the plans and elevations drawn. In the sketch process, we could develop some of the details. To produce the two renderings required 7-1/2 hours.
