Oh so cool you noticed that we're trying to achieve a french country/industrial look or did we write that somewhere? I've attached some other photos of a bedroom and the foyer (of those we've taken so far), but are absolutely open to suggestions on a "beachy" feel as well or instead of. Although because its a beach house we don't want to go over board on expense and hence keeping what we already have, and just adding personality to it, if you get what we mean. Kingsize Black upholstered headboard to come in that bedroom.

Deep gray and all the other accents in silvery old wood and cream. This will add drama, allow the other elements to bring ion light and set off the concrete wall as a true feature. If you want light instead of drama, then go for a very pale beige stone. It will echo stone colours in both the concrete and rocks...

We are planning to use a dark taupe on one side of the lounge (left wall as seen in plan), and the same dark taupe in each of the bedrooms (1 side only, wall behind bed). Is this a good idea or would u prefer using a diff colour for bedrooms? Thanks

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