I recognise that hall - it's been a well known jw hall in Bristol since before I was born (early 1960's) - that photo is taken from a road bridge over the local commuter railway line and the hall has a basement which is down behind the hedge in that photo.
It's a posh part of Bristol too - near the University and on the borders of Redland and even posher Clifton.
A really good site for developing even if a new developer has to keep the exterior looking the same.
The world famous Clifton Suspension bridge is just over a mile away.
