I'd go with blue, white or silver gray.

Hi @whizzywig - this is the current layout: On the ground floor the lounge, small bedroom and main bedroom all look out onto the courtyard so the glass is in place but could do with an update eventually. We acutally viewed some Span estate houses with a view to buying - Field End, Cedar Chase, Weymede, The Plantation. But in the end we found this place on a small estate in SE London that fitted the bill.

Definitely, my friend has done just that. So granite worktop and upstand, but where the window is the upstand reaches the window ledge, and then the ledge is covered in granite too. Very easy to keep cleaned and very tidy!

Lovely space! Very quirky and individual. Do you mean minimalist in style or in budget? Your blue chairs made me think: blue for the bottom cabinets and white for the uppers. I think a light blue or a light green might be lovely, but you'd have to see what goes with the floor. A solid wooden worktop will be nice, but you'll have to be careful around the sink. Or maybe part wood part stone countertop, since it'll have to be in three parts anyway, if I'm correct? You could then do stone around the sink and wood on the other parts. The walls look very yellowish. I'd be tempted to paint them white and add a funky tiled backsplash.
