It's nearly impossible to pick a last building to highlight for our Doors Open series this year - over a hundred and thirty are left to consider - some on the list for the first time, some for the first time in a long time, some that are on every year. Maybe this is the year to go to one of the every-year bunch that we've missed in the past. Maybe it's a case of only running around to the first-timers. Maybe it's a case of heading to a part of town that we're not normally in, and doing everything in that area.

Hard to pick one... so here's 10 more notables: (with apologies to those that we don't mention) City Hall Podium Green Roof - well, we've gotta see the brand new green roof, the first part of the makeover of the whole square.
