We kicked this year off with a great project - converting three separate flats (one on top of the other), back into one large 3 storey house in Wimbledon. This was a tricky one, it meant 3 separate gas meters. 3 separate boilers and central heating systems. 1 shared water main, which split off into 3, 2 of which fed flats directly and one which fed a cold water storage tank in the roofspace. This basically meant a full gut of all the plumbing, and heating pipework and a restart from fresh.
