This is the proposed location of thew retirement home: https://www.google.com/maps/place/Cemex+House,+Coldharbour+Ln,+Egham+TW20+8TD/@51.4083884,-0.5216377,534m/data=!3m1!1e3!4m5!3m4!1s0x48767721c5ad4327:0x761f1c38214c6e0a!8m2!3d51.4096667!4d-0.5208182
It's very close to a major back of house service road used by the park, as well as the island behind Stealth/Swarm which will probably have a new coaster put on it the next 20 years (hopefully..)
It has been discussed since last summer, and is clearly a bad idea given it's proximity to the park and it's service roads. I wouldn't be keen to live there; why would people needing a retirement home want to?
Quotes from Thorpe's representative taken from their letter of objection letter to the council...
It further mentions that the noise assessment carried out by those planning the retirement home (which says the noise levels would be fine) were carried out improperly, and probably understate the amount of standard noise. That could cause major issues if the development went ahead.
