There's a lot of misinformation in this thread. When Openreach build a new fibre-only site they really mean that - you don't get a copper phone line. You get 2 voice ports on the fibre termination equipment which can be used to make phone calls, but for obvious reasons they can't be used for ADSL or FTTC.
For now BT are the only supplier that I am aware of that provide services over FTTP/FVA, but there's nothing stopping Sky, Zen, TalkTalk getting on board. Chances are by the time these apartments are finished there will be at least one more option.
And yes, FTTP is commercially available in areas where it is installed, it's way past the trials stage.
