Unfortunately I don't have any better pictures at the moment...

It is currently being used as a laundry room. The walls are covered with beadboard looking wood which is original, and it has a couple of shelves and a mirror which may be original. I suspect the door and window in the foreground of the first picture have been added later on. The second picture shows where I suspect the original door was. The third picture is a crude but pretty accurate drawing of what I believe the original layout of my house was before it was added onto in the late 20s early 30s... The room is labeled with a question mark.

Pantry with possible door to the exterior for ice delivery?

It was most likely a utility porch. Almost every bungalow had one, typically right off of the kitchen. They were often screened in, although in northern climates having a utility porch that was glazed with glass windows was not uncommon. They usually had beadboard ceilings, and either beadboard or siding covering the walls. This is where tools, mops, etc. were kept.

Often times there were milk doors leading from these porches directly into the kitchen. In areas which had alleys the deliveries from the milk man, ice man, etc. were made from the alley side of the house. In areas which did not have alleys, these delivery doors are often located on the side of the house, which often had a smaller service sidewalk leading to them from the street.

I have one. It was called a "breakfast room" when we bought the house. The previous owner (she was the original owner) used it for a sewing room. They had also installed a tiny 2-piece bathroom in there during the 80s when they were too elderly to walk upstairs every time.

We put our laundry room in there because we couldn't fit the new style machines down the stairwell into the basement.
