How to determine if structural support is adequate on an addition

We are buying a home that has a 14' x 17' addition that was added to the side of the house. The lot is sloped so the addition is raised about 8' off the ground, although it is attached to the first floor. The only vertical support posts holding it up are one pressure-treated 4x4 in each of the far corners and two other 4x4's about 4' away from the corners along the outer edge. The horizontal beams seem to be about 12" x 12" and rest on the cinder block foundation - you can see this from the basement.

With a room this size, we're wondering if more posts and larger posts would be necessary to support the weight of the room and all the furniture in it. It seems like decks have more posts beneath than this room does!

Any ideas on how to determine if this is safe would be appreciated. Thanks!
