Normal
I have done 3 of them and one we put in a little wood burning stove for heat and it had a hot tub in it .For coolness the owner just leaves the sliding patio door open going into the house.Lots of windows in 2 of them.The add on I did on my house I removed the sliding patio door and left it open and trimmed it out in wood.My add on has 2 rooms and does not look like an add on.There is a den on the other side of the exterior wall I tunneled through it at the bottom where the floor register is at for the central HVAC and put a plate over the register in the den and made it blow into the add on room.That may be an option for you.Permits may need to be pulled in your area.I did not pull any permits. It's my house and they can pound sand.But if you go to sell it it can burn you on the deal.Insulate it very well and go for 6" walls.And know this Argon filled windows block out a lot of sound which is beneficial in noisy areas.
