Tiling into an extension

[pcolbeck]

Hi

We are having an extension built to our living room / kitchen. The extension is about 6m x 2m basically the full length of the existing room. The floor will be concrete as is the existing floor. There will not be any under floor heating. My wife would like to tile the whole of the room with limestone in an opus roma pattern. Will this work OK with a decoupling membrane or do I really need to persuade here to go for something with a continuous straight line through it for an expansion joint ?

Thanks

Pat

:welcome:Is this a solid floor ie. screed/ concrete? Sorry I missed concrete, is there a screed or leveling compound?

between the old and new floors will need an expansion

agree expansion joint needed you could use a metal type as to make it look like its meant to be there

yes you will need an expansion between the old and new floors,as jays says,you can use a threshold strip and it will look fine as you walk from one room to another

The issue is that that it wont be two rooms. The extension is just making the existing room 2 metres wider.
Both the existing floor and the new one will be concrete. We could lay a self leveller over the top if that would help.

Thanks guys, I think we will go for a Flemish bond pattern then so we can have an expansion joint without it looking too unsightly.
