Re: sunroom addition
We are in the process of adding on basically a 15' x 30' sun room addition. One thing to keep in mind if you choose to use it year round is if your furnace is big enought to heat the room. If it isnt you can still go year round but instead install a wall baseboard type heat unit. The wall unit is really the best way to go because it likely is cheaper than running duct out to your room.
Also if you live in a housing addition make sure your room will meet the convenants that are required by your association.
