Who owns High Kingsdown?

The flats and houses are on 999 year leases. 
The garages are freehold. The particular colour of green that the garage doors must be painted is specified in the deeds. 

The common areas are owned by the Council.  The intention is that negotiations will take place to transfer the power to maintain these areas to a company associated with a charity, controlled by High Kingsdown Residents Association.
