Hi,
I know this has been an old thread, however I thoughht I might share my experience as well as a buyer, which has been mixed, I have bought a Berkeley home in London.
I like the fact that all the flats are high spec, has good quality fixture and fittings. We've had lots of minor issues(10+) with the flat when we moved in, although all the issues have been fixed quickly by customer service, nothing major. Customer service has been very helpful.
One thing I care most about is noise and soundproofing, I cannot hear people talking downstairs which is great. However, I have been having noise issue with their doors. All flats front doors close automatically, however the doors are hefty and all of them slam hard. When neighbours on the same floor as me leaves their flat and close their door, my door vibrates and slams too from turbulence. Also when my neighbour goes to work in the morning, their door slamming can wake me up, and this neighbour lives TWO floors below me, not even directly below me. I could hear them even wearing earplugs - shocking!
Neighbours weren't being a nuisance as they were just letting the doors shut automatically. Berkeley never bothered to adjust their doors when people move in, so every single door in our block slams really hard, just like an earthquake that make people jump.
Would I buy from Berkeley again? Not sure, I'd be more hesitant, peace and quiet, and sleep is so important.
