"They've" recently done a refurbishment to a KH in the south-west of England. This was a "nice" hall last done in the late 1980's / early 1990's by the two congregations sharing and it was so well done it was the go to hall for elder schools, pioneer schools and the like. A circuit flagship hall.
It (unusually for the UK) had air-conditioning with chillers, nice seats and a raised section of platform for the sisters talks and sitting down school overseer (remember that little fad?)
So what has happened in the great refurb? Like Slidin Fast says - it's a shed.
Now 4 congregations share it (one of which had its hall summarily closed in preparation for sale) by the UK branch. It is an austere grey colour with a very low platform like in the pictures shown on the previous page and "they've" (LDC/RBC whatever) ripped out the air-conditioning and it has retained it's non opening windows (which were fine when they had air-conditoning but now just keep heat in).
An inmate err.. congregation member of one of the congregations told me that one evening earlier this summer the outside temperature was over 30 degrees C and inside it felt like being in a warehouse shaped oven.
And "they" wonder why meeting attendance is down.
