TDR (Transferable Development Rights)
Building regulation
In one line
Development rights detached from one plot and used on another.
Where land is taken for a road or reserved for public use, the owner may be compensated in development rights rather than cash — a certificate letting them build extra floor area on a different plot, or sell that entitlement to someone who will.
