planned
An active structure proposal with a reasonable likelihood of future construction, before the first foundation element is installed.
Structures listed as 'planned' are active proposals which have a reasonable likelihood of starting construction in the future. This phase spans the time from the initial public announcement of the design until the first segment of the structure's foundation is laid in the ground.
In general, structures should only be listed as planned after an architectural design has been created. Vague development plans should only be listed when the proposal is serious and important, and when basic specifications have been released (usage, floor count, exact location).
The phase includes approval and site preparation before foundation installation. Physical clearance or excavation can therefore occur while the structure remains planned.
