The pool is just block at the moment. I can ask the architects about the finishes for it.
nice one mate if it's block it might be rendered/tiled this is about the time we usually get involved ,looking at the pic's, but they might alresdy have a pool company or someone ready to do the job ! well it's worth a punt tony & as i said it could be worth a few bob for you too, so give it a try mate !! :-D
