If you’re looking for a sunroom, how about something like this? Full foundation with heated ceramic floor. Lots of Pella windows for plenty of natural light yet with blinds between the glass for when needed. We also installed a gas log fireplace diagonally in the one corner which can be seen even from the kitchen which is adjacent to this new room. The exterior was done to match the rest of the house so it looks like it’s always been there. What a great space to enjoy!
