Just a couple photos of the tilt and turn (we usually call them German or continental) windows that we really like for the ventilation options.

In Bedroom 2, it's a huge window (about 1.5m tall). And we'll going to restore the Victorian fireplace and might keep the floorboards exposed after we get the walls replastered ... which is a different issue (should we go with sheetrock over the brick, hardwall, sand/cement or lime plaster). We're leaning more toward lime plaster as the walls will breath better. I need to rebuild the wall to the left of the window and underneath it as most of the original mortar is worn away.

We went with white on the inside of the window and anthracite grey on the outside.
