Reversible move
A small-space change that leaves no permanent mark and reverts at move-out — a leaning mirror for borrowed light, tension-rod shelving, sheer curtains (the originals boxed), freestanding storage. The vocabulary of the method under a rental's no-structural-change constraint.
Changes that pack and leave
Three of the four levers are already reversible; only Extend's building moves (lofts, carved openings) need substitutes — a mirror for the carved window, a tall freestanding unit for the loft. The method survives the lease.
