Church House is found next to the mini roundabout near Waitrose. It has a blue front door. For a ramp for buggies or prams, please come to the back door by going under Archway House as if to park for Waitrose. You'll see the back entrance for Waitrose and before that on the right, a little car park. Go in and you'll see the blue back door.
There is a lift to take you to the first floor if needed. The door needs to be fully closed for the lift to move.
