This application is with Greenwich for determination, against a statutory target of eight weeks. Over the last year Greenwich decided outline applications in a median of 20 days. More in our guide to how long planning decisions take.

About outline applications

An outline application tests the principle of developing a site, holding back details such as appearance and landscaping as reserved matters for later approval. More in our guide to planning application types.
