So true...I have never come across a floor that has been properly fixed by a pro carpenter
Just click on the picture above, That will move you on the flickr site, Than you can see the picture in the full size 3000x4000px.
9mm ply fixed with 3 inch screws, gap around the perimeter is around 5-10mm, you can see it next to shower tray, the rest is under skirtings.
So true...
Thank for opinions guys,
So I will centre whole floor to get mirrored cuts both sides of the room like whitebeam said
