Wasteful circulation
Movement forced to be longer or wider than it needs to be — you walk around an oversized sofa, or take the long way because furniture blocks the short one. The movement is needed; the excess isn't. Reduce it by re-placing what's in the way.
The reducible kind
Right-sizing one oversized sofa often straightens a path and gives back 8–12 sq ft of circulation — free, in an afternoon.
