The existing building is being converted into an office/residential unit, and there is definitely the possibility of storage space.
I would, of course, have sketched the floor plan completely differently if we had demolished the old building and I could have placed the bungalow lengthwise.
The old building is not connected to the new building, but as can be seen from the sketch, there is a terrace east of the old building/north of the new building, hence also the exit from the utility room towards the north.
