We meet at the William Hobbayne Centre on the junction of Boston Road and St Dunstans Road, Hanwell, London W7 2HB. There is a free car park outside the centre. Wickes is the other side of the road.
If you're coming by bus, there's a 195 and E8 bus stop outside and we're just a few minutes' walk to and from Hanwell Broadway and the fantastic bus services that run along the Uxbridge Road.
Here'a a screenshot.
