Is this in the plan of STS - House system?

[Hercules]

In the last pic about house system, I look a box. My question is:

Is this part of decoration or is a new type of inventary?

If this is a new House inventary that will be amazing, because we can have a new space with diferents slots for each piece of our house. The materials can be taken from our inventory for inventory of our own house and each piece can be classified allowing us to better navigation than we need.

Example: Type of floor, Furniture, decorations, pictures, painting, walls.
