0 a covered area or room on the outside of a house or other building, with windows and sometimes a glass roof, that receives a lot of light and heat from the sun:
An all-window, high-ceilinged sun porch was attached to one side of the house.
Now that we have a sun porch we decided to take full advantage of it and keep our herb garden indoors.
To pass the time, she sits on the sun porch watching her neighbours.
I live in a lovely little valley and I can just look out the windows of my sunporch and get inspired.
