This dome appeared on the roof of the Pebble Mill office block circa 1980.
The following comments about were posted on the Pebble Mill Facebook page:
Annie Gumbley Williams: The dome was built to be used for recordings, interviews etc. Remember doing one there with Robin Cousins in Roy Ronnie & Roy Norton days. Roy Ronnie used it for meetings sometimes to get out of the office. It made a lot of noise when it rained so not good for recording!
Malcolm Hickman: It also acted like a greenhouse and anything left in there suffered with the condensation.
Andy Shepherd:The dome was bought second-hand from Granada who had used it in the summer of 1979 for their Saturday morning children’s show The Mersey Pirate. The show was based aboard the ferry MV Royal Iris moored at Liverpool Docks. The dome structure was built on the promenade deck of the vessel. The run of the series was cut short by the ITV strike which started in August.
Here are a couple more photos of the dome being installed in 1981. They are from Stuart Gandy.
