Not really about your question but there were a large number of yards off of the ancient streets on the west side of Croydon High Street. Surrey Street was served by a number as were the neighbouring King's Street, Bell, Hill, Middle Street, Church Street and others. A number still exist, including Fellmonger's Yard and Dog & Bull Yard off of Surrey Street. You were correct to say that Overton's Yard once house the Overton's brewery (it closed in the 1950s) but this was not the same as Overton's Yard. Many of these yards ran into each other, I remember standing on the roof of a nearby business and still being able to make out how many of them joined up, but with walls, fences, sheds and other buildings they had been separated. These days there is little chance of them being reconnected, although it was once a possibility, because BT own the large building behind them all (it was built by the then GPO and was therefore Crown property - they'd not get permission these days!) and because this is an international switching centre (one of four in the UK apparently) the security around the building is such that the area is off limits to most of us mortals. It must be remembered though, that the redevelopment of the Surrey Street/High Street area back around 1895 swept away much of what must have been some pretty insanitary hovels and alleyways, so we might perhaps not mourn their passing too much.
