Two Storey house (external design) SKETCHUP

I have a preliminary floor plan of a two storey house (with possibly one additional room at third level) There are still adjustments to be made, but the footprint is almost fixed. This is to be a mid-century style. or similar to work by Walker Workshop (look them up), with clean lines and aligned planes. I need someone who can MODEL the exterior and SUGGEST facade treatments. The site is small and the footprint constrained by a number of factors. Interior modeling/planning/plans are NOT required - you will work with the footprint and general layout that I have This should be a fun little job. Style and placement of glazing and solid walls, how the roof could work and factors for consideration. Preliminary ground floor is attached. I can add notes about changes that I'm proposing. I can supply floor plans in Sketchup, and I'd like the output to be in SU also This is NOT a major project. it's more about ideas and possibilities at this time
