How to Design a Four-Season Porch
A four-season porch, also called a sunroom, projects from the house and has windows on three walls. All those windows provide a source of passive solar heat. You can design a four-season porch from scratch as an addition to your house or by converting an existing open porch. As an above-grade heated room, the square footage of your porch can be included in the total square footage of your house.

Tips & Warnings
Ensure that the outside space your sunroom will occupy can accommodate it within the property line and applicable easements and away from established necessities like a septic tank and buried utility lines.
The appeal of sunlight in a four season porch can also be its detriment. The room can be hot in the summer.
