I have just taken a couple more pictures (excuse the untidy house) from the stairs. As you can see it's an open plan area that isn't that big but very high ceilings also in wood (Macrocarpa) with dark wooden beams. The house is surrounded by bush so quite a dark house. I initially considered a darker wood similar to the beams but not sure if that will make the house appear smaller / darker...I'm really not sure what to do!?!?!? Thanks

Photos would help us a lot but mint and grey usually goes well with charred oak.

Sorry for the delay....well I still haven't quite got to the floor yet. I have friends and family advising that black would show up every bit of dust etc and one friend who had a shiny black floor and felt that she was forever mopping, and if the light shone on the floor on the wrong angle you could see where the mop had been. I think this would frustrate me too much especially with young children and a cat so I think a whitewash look could be a good option, or reclaimed battered timber perhaps.......see why I haven't chosen the floor yet. Lol. You could always go a black but a weathered matt reclaimed timber that could look good too. Good luck!

Well done its going to look beautiful! I would consider have both! Even if you have the wall light above the bed a lamp beside you will act as task lighting for reading at night, whereas the wall light is more for lighting the room itself. Find lighting that compliments each other or from the same range for a cohesive and subtle look.
