Few pics of the deck and couple of exported images of the design.

Yes, built it 2yrs ago. I can share the design and pic of the final product if you like.

You could try sweethome3d (open source). Although I haven’t tried to design a whole house, I’ve used it for designing my deck layout. Take a look at the gallery to see if it fits your need - Sweet Home 3D gallery You can try it online through browser or download the installer ( Windows/Linux/MacOS)
