I prefer beech - I love that golden colour. Birch is sometimes too white for me.
All our stuff at home is a mix of beech, pine or birch. (pine bookcases, birch chairs, birch tables, birch stools, beech kitchen, beech sofa frame)
We try to have real wood and no laminate or veener or plastic wood-coloured stickers or MDF or chipboard.
The only fake wood is my desk which is an ikea beech (veener) desktop as a real 3x5 foot wide slab of beech is too expensive.
Carpet is cream, warmed up very slightly so it's warm cream colour, not cold cream. (it's a nightmare with kids and babysitter but we wanted to treat ourselves to a one off.)
Walls are organic white paint, which looks slightly like chalk white, but again slightly warmer. (normal white paint is flat and dead by comparison)
White linen curtains, with ikea beech slatted blinds.
Accent colour is bright red, (red sofa, red bedspread, red cushions, red kettle, red cabinets, red pram). It bounces off the carpet and walls, and makes all that white seem warmer.
Looks fab and I love it - everyone says it's so peaceful here.
