Please be sure it is really what you want, the new house I mean. Something similar happened to me, DH wanted a new big shiny house, and even after trying to live there (5 years) it never lost the 'stark and new' feel!! Think at the time I was a bit PND and was like 'whatever' re the move.
I love my new build, but it does take some time as unlike a resale you have no mirrors, no curtains or blinds, no fixings for pictures, no toilet roll holders, no shelves etc. So buy a good power drill is my number one tip. Ours was painted "Soft White" which we softened with feature walls in all rooms but the lounge as this had a fireplace, three windows and patio doors so plenty of "stuff" to soften the room.
Eve I wonder if you are buying on my site and they were talking about me....
I'm in a new build and I love it. I've only been here since December so it's still stark white. Nothing up on the walls yet apart from a bathroom mirror. I'm just waiting until I see things that I love. However I absolutely adore the clean, new, whiteness. Exciting times for you!
