We are building at the moment, get our keys in just under two weeks YAY. So can't really comment if what we've chosen suits us or if we'd change anything but as PP's have said - power points, you can never have to many and make sure they are placed for any possible furniture upgrades/room rearranging.

A couple of extra's we added were also extra garden taps and outdoor gas outlets to run bbq and/or outdoor heaters.

Lots of kitchen benchspace was a must for me (my previous kitchen was a matchbox) and after looking at display homes I "needed" a walk through pantry, luckily DH agreed I kinda of wish my laundry was a bit bigger but we added extra cupboards in there so hopefuly it will be ok.

Think someone also mentioned making sure you visit the site as often as you can to pick up issues as they crop up, we've had a few along the way and not entirely happy with response to concerns with our brickwork so we are getting an independent inspection and report done before handover.

Best of luck with it all
