A building is considered to be 'Proposed' (i.e., a real proposal) when it fulfills all of the following criteria:

1) Has a specific site with ownership interests within the building development team

2) Has a full professional design team progressing the design beyond the conceptual stage

3) Has obtained, or is in the process of obtaining, formal planning consent/legal permission for construction

4) Has a full intention to progress the building to construction and completion

Only buildings that have been announced publicly by the client and fulfill all the above criteria are included in the CTBUH "proposed" building listings. The source of the announcement must also be credible. Due to the changing nature of early stage designs and client information restrictions, some height data for proposals may be unconfirmed.
