Sorry I'm new to this!!

Yes it was on Queen Street, Maidenheaad but I maybe wrong about what's there now - could be an estate agent. I took a picture of the church window, which is on the first floor, last year and the building has 'surveys' on the ground floor window & a part web address - www atk. Sorry I don't know the road names but the building is on the corner, or near the corner, of the road that comes down from the main car park, crossing Queen Street and going towards the Town Hall. If you turn left into Queen Street (not sure you're allowed!) it's on the right. I think it was actually a chapel though, not church.
