AI designs the layout: float positions, rug placement, conversation zone, visual balance, and walkway map. Same furniture. Looks professionally arranged.
Floating furniture 4–8 inches from walls creates depth and makes rooms feel larger (counterintuitively). Every designer does this. Almost no homeowner does.
A rug anchors a seating group when furniture SITS ON IT (at least front legs). Too small = floating island. Right-sized rug = the room looks intentional and cohesive.
The 'off' feeling comes from breaking proportion, balance, flow, anchoring, or grouping rules. Fix the broken rule and the room transforms — same furniture, different feeling.
These 5 rules are what separates amateur layout from professional. They cost $0 to implement (you're moving existing furniture) and produce an immediate visible difference.
