The location is a bit tricky. Assuming you are driving north up Edgbaston Park Rd. you need to go past the signed main entrance to Winterbourne and take the next right. It is a gated narrow gravel road that leads to the rear parking for Winterbourne. If you see lots of glasshouses you are in the right place. Meetings are held in the first building on the right after the first parking lot. You can make it out by using the Google Maps Satelitte image below.
