@spacekookie #Blender, #SweetHome3D or maybe simply #LibreCAD ? It's 2D, but for layout work it might do the job well
@spacekookie then i'd go with #FreeCAD (but I have a biased opinion :D ) or #Blender, both would be adequate, FreeCAD is more technical, Blender easier for free-form modeling, depending on what you need more
@yorik I don't just need it for 2d layout, I live in a roof apartment so the height parameters are really important.
