Yep, you should defenitely call them, modern kitchens, bedroom elegance and fireplaces direct, it was just by chance that we found out, any changes we made cost extra, the builder is very expensive if you want them to put in extra sockets etc and you have to pay him up front, you can change the fireplace, and alter the colour and amount of kitchen presses, one thing is if you want to change the kitchen drawers (they are very wide) then the cooker is moved over, the builder has to move the hole in the kitchen wall for the extractor fan, they should tell you all this anyway, also the builder will do the tiling but only after your snag list has been done and you dont get a shower connection in the main bathroom unless you get them to put one in!!!
