DERA Hall - easiest route is to park in ( or walk up) Meadway, which you can see on map below. From the A316 end of Meadway its a 2 mins walk ( back along A316 towards Richmond i.e turn right at end of Meadway) to the hall. Access is via a small alleyway called Chertseydene walk but the hall is visible from the pavement on the A316 so you can't miss it.

Kneller Gardens - when weather is good we  have  classes outside (check Noticeboard) in Kneller Gardens - the green space (sometimes grey on map) on RHS of Meadway (if you're heading up to A316) on map below - meet by bench on north /north-east  side of the park - side furthest away from Meadway. Best to enter  park over little bridge from Mereway Road and we will be  ahead of you. NB there is sometimes another Tai Chi group that meets a bit further over to the left (if entering the park from Mereway Road bridge) / west towards Meadway. Don't join the wrong group !
