It is not possible to provide a precise figure or date for the completion of the Gateway site. It was part of a larger acquisition carried out prior to 1959, which was itself part of the land assembly to support the creation of Harlow New Town. To determine the precise date and cost of the acquisition of the freehold of this site would represent a disproportionate cost.
The Gateway site was disposed of in 2004 for the figure given in my previous answer. The freehold is being transferred on a plot by plot basis as units are completed. It has therefore been transferred on some of the land but not all.
Nothing was spent by either the HCA or its predecessor bodies on security for the site.
