I was amazed at how run down the court was. The historic parts of the building were lovely, but the "behind the scenes" rooms were all reminiscent of the 1980's / 90's as far as facilities and decor go.
That's true of every court I've seen. I think there must have been a period of investment in the 60's-70's, then barely anything since. Certainly a lot of courts in my area were built around that time (and often in conjunction with new police stations that came with force amalgamations).
I was at a magistrates yesterday and the temperature was stifling; there were fans running in the court rooms. I presume this is because the heating system only had one setting. This court was built in the mid seventies and when you walk around it, it's clear nothing substantial has been touched since it first opened. There's an amazing grade II listed crown court near me which has lots of beautiful features in the public areas and in the courts themselves, but the non-public areas are all very tired. It's not really fit for purpose any more (e.g. cramming several 80" screens and live link systems in to 200+ year old court rooms, uncomfortable wooden benches and almost non-existent HVAC), but it's highly unlikely anything will change.
