you put it all together yourself?

Mostly. We had a fitter run the gas for the hob (and tidy up the plumbing), and a carpenter came in to do a couple of fiddly bits (like cutting the end cupboard down to size -- the walls aren't strictly vertical). We also got someone in to do the tiling around the worktops -- I can tile reasonably well, but I find it deadly tedious.

For the cupboards, I had some help from my stepdad, but Jen and I did the rest (worktops/units/flooring/sink/lining paper/painting) ourselves.

All told, it's taken us about 6 or 7 weekends, but it's taken 6 months, because we've usually been busy at the weekend (and we were lazy about getting the tiling geezer in).
