3D écological house

Hi there,

I am a new user of blender. I still try to figure out how to put textures with 3 dimension on it using all render layers.
But anyway I wanted to have some advices for this tiny house.
I tried to model every material to help people construct it.

The blend file is available from my web site here.

By the way is there a way to publish opensource blender files on GNU or Creative Commons at a place?

Thanks all of you for your comments, help, advices.



Here are some additional images for preview.

I didn’t modelled too much details like screw and fixations.
This house is made from wood and square straw bales.
There is a ground air exchanger.
I intend to design a green roof.


Sorry, duplicate post.
