How can you not need something for the house, my niece said this recently and I said you might not need something, but you must have a luxury you would like. I ended up buying a clock to stand on the side. She would have liked a wall clock but is in rented so has problems with hanging things on the wall.
I would suggest a picture/painting, but again can he hang it on the wall.
How about some nice lighting, and floor light or something.
How about some crystal glasses, everyone likes something special, you could add a bottle of bubbly
