Our gas furnace is currently located in an unheated storage room. It is only accessible from an outside door. The door to the storage room has a louvered vent (I think to supply fresh air for combustion???).

We would like to utilize the storage space and for a larger laundry room. Would we be able to do this?

This is the existing layout with the storage closet/furnace room:


This is the NEW layout with our proposed laundry room:


Any help would be greatly appreciated!
