Converting your patio into a patio sunroom will increase your home’s value, offer a convenient place for guests and special occasions, and provide a place to grow plants in the right environment. A sunroom is the perfect place to relax and enjoy a quiet breakfast with the sunlight streaming in. Watch beautiful indoor plants show off their flowers as they grow in their ideal habitat.

Although a seemingly daunting task, once the right materials are purchased and with the right tools, this project can be completed in two or three weekends or a single week. Patience and planning make this a project almost any homeowner with minimum mechanical skills can undertake. Here's how to get started.

Step 1 - Prepare and Plan

As accurately as possible, begin by carefully drawing out a strategic plan of the required measurements and structures. Plan out the flooring with the 2x4s first, then the grooved flooring base. Layout the dimensions of the wall structures, where the windows and doors will be placed, heights, widths, and total number of 2x4s needed.

Step 2 - Level Flooring

Dry fit the flooring materials in place and ensure cuts are to be made at the correct locations. Be certain enough material is on hand and that compensation is made for the uneven flooring of the existing patio. Use the large level to check for evenness of the flooring 2x4s. When placing the grooved flooring base on top of the 2x4s, mark the location of the 2x4s so that nails are driven squarely into them. Although a hammer and nails will work well for this job, a compressor and nail gun will save a lot of time and energy and do just as good a job.

Step 3 - Check Horizontal and Vertical Fit

Layout the 2x4s for the construction of the walls and measure as accurately as possible. Carefully consider where windows and doors will be placed, as their height and location cannot be moved after installation. Use the large level throughout the building of the walls to ensure horizontal as well as vertical level. Mark everything clearly and carefully, and be sure to cut all pieces up to the pencil line. These can be sanded or trimmed if too long or wide, but cannot be stretched if too short or too thin. Having everything measured and in place will speed up the completion of the work.
