a sudden breakthrough

While it is hardly a case of this:

I just couldn't wait - so today I got onto the angle-grinder and spent a few hours cutting into the walls to open up between two of the containers.

This one is between the perpendicular container and the end of the three that are side by side.
It will eventually be a much larger gap and is in the corner of the open kitchen-dining area.

I can't cut out too many walls just yet until the steel supports are put in. But a couple of small doorways won't hurt.
