The first time we ever tried this was Dec 09/Jan 10 and after the utter mission up the stairs we were met with a locked door. It has been that way for near enough three years however, there are some newer guys running things in Manchester these days and the main man Anon sorted us out.
GNT was completed in 2007 and covers 257 apartments, it has a distinct sloped roof similar to that of the Edge and No1 Deansgate apartments. Back in 2010 I tried one of the lower roofs, chilled up top for a bit before a security guard just popped through the hatch. Instead of flipping his lid he asked what I was up to and we had a decent chat about exploring.
Shouts go out to Anon, Skudge, Ms Skudge, Nick & both Andy’s!
