Dynamic rollover? Don't think so, looks more like disymetry of lift caused by increased induced flow on the building side. Does no one remember their basic PoF lessons warning of the dangers if hovering too close to a hangar? Be warned, Oh best beloved.

SL, the 'dynamic rollover' reference is in relation to the 'granny vid' wetbulb linked to, not this Longford incident as in this one the skids didn't get chance to touch the ground.

P1DRIVER;
The a/c was perfectly serviceable up to a split second the starboard rotor blade hit the building !!!!

Just having another look at the video...
I'm wondering if the first point of impact was the MR making contact with the lamp-post. And if the hole was taken out of the building's wooden cladding by the tail as the aircraft was suddenly rotated.
Have a look at the marks on the lamp-post (roughly in line with the middle of the open window in this photo). Having watched the video a couple more times, it seems this way, but perhaps my imagination.

As you can also see on the other posts, including those on the other side of the canal;

Sid, I reckon, based upon Google Earth that there is about 20ft between building and canal.
Than being the case, in a side-on landing, as was attempted, the left skid would be about 6 inches over the edge - so actually no room.
And in a nose-in attempt, there would only be inches to spare between MR and building with the skid heels flush with the edge.

Anyone have any cuttlefish?
Anyway, it will be interesting to see the 'cockpit gradient'

This pilot considered that the landing site was quote "tight" but "very do-able". It was later proven that the rotor tip clearance was 81cm maximum.
IIRC on SAR, with a crewman to monitor tip clearance, the minimum tip clearance for non life saving was 10 feet laterally.
What is your personal minimum for lateral rotor tip clearance? Does your company publish one or is it left to your discretion?
