A French man building his own house ...

Hello everyboby
I am beginning with LibreCad.
I am going to use it for drawing the new plans of my house : I have juste brought it an I have to enlarge it before to live in it.
I am married and I have 4 children (So I need a big house !)
My future house being less than 170m² : in the french law an architect is not mandatory, so I decided to draw it myself...
And here am I !
Thanks for helping me if you can !

Hello Lamy

Busy man with 4 children and new house ... good luck and best wishes.
