Definitely smaller than the depot but tiny is probably an overstatement. The 1100m^2 is just the climbing area of the new TCH whereas Kevin's number is presumably the total footprint of the depot. Worth bearing in mind that the depot is also pretty spaced out, depending on the design of the new TCH they could most likely fit a similar amount of wall in to the space.
By way of another reference point, the original works (i.e. not including the mini works or unit E) is 780m^2 total.
