Hello David,
I have a little complaint about your site.
1. I can't find a English language translation button in your site. [:-&]
2. Is there is any modular kitchen(full kitchen) models are free to try? then please make it as SH3D furniture library and connect that link with SH3D. [:>]
3. In my opinion if you really like SweetHome3D then please add http://www.sweethome3d.com/ link at any where in your site.
