Default Dolphin layout perfectly fits this system. There is already 10px margin between columns and blocks. And you can change columns width in page builder to match these values. And whole page width is changeable too.

Thank you - BangLoungeFM for the link to Firefox plugin, it looks very nice and it really can help in developing design layout.
