On 28th March 2025, Acorn Developments submitted a planning application to develop on the site of the Blackheath Station car park. 

This development is neither wanted nor supported by the local community. Of the (unprecedented) 651 public comments submitted to the Lewisham Planning Portal, 632 (over 97%) people came out against the development with just 13 (under 2%) in support.

A number of public figures and celebrities with a strong connection to the area have voiced their concerns about the planning application and have put their names to an open letter written by author and historian John Willis. Signatories range from Hollywood A-listers Jude Law and Dominic Cooper to music industry giants Mark Knopfler and Jools Holland to civic and political figures Sir Terry Waite and Dame Joan Ruddock.

More recently, 80 local businesses including the Blackheath Conservatoire and Blackheath Halls got together to submit to the council a letter of objection to the development proposal.

The campaign to stop the development has been featured on ITV London news as well as in numerous press outlets including The Independent, The Telegraph, The Architects Journal, The Sun, The Express, The Daily Mail, My London, Time Out and News Shopper.
