It's been a long day and my mind is clearly wondering bridgman. Not sure the origin of the name to the surfboard, could quite possibly be the band. I just really liked it. The company I worked for was Canned Heat which was also a band, hence the confusion \:\)

Where I live all our walls are brick and plaster, no drywall, so false walls are not the done thing really. Everything gets chased into the walls with angle-grinders and conduit so getting it right first time is important. Also with where the windows are it will not really work.
