Im in the process of preparing to lay a concrete floor in my newly built diy conservatory.
I have a double french doors opening out into the conservatory. the doors have a upvc sill on them and just below that is the DPC for the house.

My question is: can I raise the concrete conservatory floor up to the DPC course so once tiled, its the same level as the internal house?

The new floor will have a DPC sheet then insulation, then concrete, but being it's "semi" external can this floor be the same height, or will it breach building regs?

Then no problem.

Dpc the wall so you don't bridge the house dpc.

I'm sure it doesn't breach regs as many people with conservatories do this.
