Bit more progress but I've had to finish before I really wanted too as I've run out of 15mm pipe
22mm mains cold water extended up to the first floor, terminated with a 1/4 turn ball valve just in case I ever need to isolate everything upstairs:

Mains cold water, hot water and heating flow & return extended in to the void under the stairs to serve the downstairs loo:

And then heres the spaghetti junction of pipes in the corner of the kitchen. The bottom here will be behind a corner unit, the pipes running up the wall will be boxed in again

I've terminated the heating flow and return pipes above the worktop level, so the kitchen and worktop can go in without my having to worry about making the final connections if I've not had time to progress the downstairs loo - I'll need the floor up and internal walls built before I can finish the heating pipework.

I'll run the heating 15mm pipe up the wall when I get an opportunity, but pleased with todays progress.
