Hello Daniel ! I'll give you some news ! We are coming to the end of the adventure...
Everything went well thanks to your valuable advice and hard work, but it's worth it !

We stayed focused on our cantilever project to return the terrace to the water line to hide the creases and we succeeded ! We are delighted! It remains to make the wooden staircase over an entire width and it will be finished !
The terrace that we wanted comfortable is 75m2.
Thanks again for your support when we were in doubt !
And for your good idea to make its unusual swimming pools ! Our friends were skeptical and are now admiring, we are very proud to have managed to do everything ourselves.
I am attaching some photos !
Good day !
