Exposed wood looks nice
Love the metalwork reminds me of the stars in Portaferry
Stairs and books !!! Nice
Stairs and mezzanine into the living kitchen space ? Might solve a problem, but need to be able to stop sounds rising to upper level.
Stone and open shelving also works. Love the larger island and solves the extractor fan issue if you put a hob on the island .
The dark colour would stand out against light walls.
