Changing Column Width?

I got my cards to layout like I’d like, but I’d love for them to be twice as wide: http://bru.ms/FG6BtZ

Any tips that don’t use panel: true (that breaks the whole layout and the mobile app) that would get it so that I could have wider columns? I’d like this to be 4-columns wide, with the floorplan taking up the left 2 columns.

Here’s the config: https://pastebin.com/fkmTPsqZ

Thanks!
