Rooms above Porta Marina

We have just returned from Pompeii with 10,000 new photographs which we will be busy adding to the site over the next few months. The first pictures including The House of the Lovers and the House of the Floral Cubicula were added at the end of April.

We took some photographs (below) of rooms above the Porta Marina. We were at the time in the lower part of the House of Umbricius Scaurus and found these rooms which we can't find in any of our books. Can anyone help us by identifying the rooms and suggesting how we can describe them on pompeiiinpictures.com?

The full set of pictures can be seen at http://pompeiiinpictures.com/pompeiiinpictures/R7/7%2016%2013%20p6.htm.

Any help will be greatly appreciated.
