Two-Story Residential Townhouse Schematic Design

I need a clear, architect-ready schematic for a two-story townhouse that will serve purely residential needs. The layout must flow efficiently while still feeling welcoming, with special attention given to a comfortable guest bedroom.

Here’s what I’d like to receive:
• Scaled floor plans for both levels in PDF and the original editable file (AutoCAD, Revit, or SketchUp are all fine).
• A simple 3D massing or concept model that shows roof form and basic façade articulation.
• A brief written rationale explaining circulation, daylight strategy, and how the guest bedroom is situated for privacy.

Please keep dimensions sensible for typical urban lots; I’ll confirm exact site measurements once we start. If anything in the brief is unclear, feel free to propose alternatives that improve livability—I’m open to creative ideas as long as the end result remains practical for everyday family life.
