The site of the Canterbury Television building, which collapsed in the February 22, 2011 earthquake claiming 115 lives, has been bought by the Crown.
The site at 249 Madras St, which has been cleared of rubble and continues to be a poignant place for remembering those who died, will form part of the new central city blueprint.
The Christchurch Central Development Unit (CCDU) has written to families of the victims at the site to advise them of the Crown purchase.
The CTV site will form part of the East Frame, a predominantly residential area with green open space that will border the new condensed CBD core.
CCDU director Warwick Isaacs says those involved in the design and planning of the East Frame are acutely aware of the sensitivities that surround the site.
"That is why we have been in contact with those affected families we have contact details for - to let them know about the change in ownership and to reassure them that access to the site will not change in the near future," Mr Isaacs said.
"Decisions are still to be made about the longer term use of the site, but those involved in the design and planning for the East Frame will be very mindful of what occurred at the CTV site, and this will be reflected in any decisions that are made.
"I have committed to keeping those families informed on the key decisions that are made about the site."
The Crown's negotiation to purchase the PGC site at 233 Cambridge Terrace, where 18 people died and others were seriously injured in a building collapse in the February 2011 earthquake, is "well advanced", the Canterbury Earthquake Recovery Authority said today.
