no good at the old meters myself, do everything in feet and inches...and i'm not even of that vintage!! probably closer to 2m x 4m or so (6.5ft x 14ft - for us ludites - handy gadget on the phone does these conversions for me!)
i reckon tiles are spot on, i've no loo in hall way but plan to tile through to the living dining/kitchen! the notion of grubby feet and all that! Depends on what kind of wood floor you put down....solid generally bout 18mm i think. so there might not be a rampa as such or if there is not very noticeable - depends on the tile!
Brodiebabe, love that black white look myself but wonder if it'll be a bit much in the kitchen aswell...i have 38m2 to do...conversion for the tilers benefit! what kind of tiles did you lay? the polished porcelain was costing me €4.5k...i think i better think it out again!
