Am going round in circles so would really appreciate any thoughts on this 
Currently planning the new extension - kitchen/diner approx 20sqm. Pretty much decided on DIY Kitchens Luca Gloss in dove grey, and speckly white quartz worktops. But can't decide what floor tiles to go for. It's complicated by the existing floor in the rest of downstairs being (very) dark brown solid wood oak. We love it, but it's not suitable for kitchens, so can't extend it (and can't afford that either!). So the new tiles need to work with that - there will be an opening into the new extension about 2.5m wide where the two floors meet.
So I think I want ceramic or porcelain tiles. I like the wood effect ones, but don't think it would look right next to real wood. Looking at various grey tiles, but then will the kitchen look too grey? I quite like slate but don't want the upkeep and want something easy to clean. Don't like the slate-effect ones as they look too fake, but maybe I've not found the right ones? I've ordered loads of samples but can't find anything I actually like when I see it up close. Help! Can anyone with an eye for design think what would work best?!
