When I look at all this my only thought is 'thank goodness it's not me doing it'.
Wills bought all the units from Ikea, and is now assembling them; whilst friend D fixes the rods onto which they will be secured. So far everything is going OK, and all problems soon find a solution.
By lunchtime most of the wall units were up, but we've now realised that there's still space for one more 60 cm unit on the right (below). We'll pop down to Toulouse to pick that up later; no point in wasting possible storage space.
He's also just realised that the floor-tiling needs to be done before the final positioning of all the appliances, so another panic trip.
Still plenty to do; I'll post pictures of the finished job, as soon as possible. Never a dull moment here!
