The Sandbox Studio, located in Tahoe City, CA, specializes in high-end residential designs.  I worked with them to create architectural drawings such as floor plans, roof plans, reflected ceiling plans, electrical plans, site plans, sections and elevations.  I used AutoCAD Architecture for these drawings as well as Google Sketchup to make digital models.  There were several different residences that I worked on with Sandbox, but only three are shown here.
