Your plans on how to build a sunroom in your home can be as simple or as complex as you wish. The addition of a sunroom will add space and value to your home. A sunroom can be a place to relax and enjoy the beautiful view of your yard. You can build your own sunroom and save a great deal on labor costs. Be sure you have the right tools and materials before you begin. Check with your local building and zoning office to be sure you meet regulations and to get the necessary permits before you begin any work.

Step 1 – Choosing Your Windows

Choose quality windows for your sunroom that will allow the natural light into the space. Determine the size of windows you want to install and where you want them placed. The window plans are very important to a successful sunroom design. You can install windows that reach the top of the walls. This will allow more light to enter the room. Vinyl windows are not recommended for a sunroom if you have plans to heat or cool the space. Insulated windows work well in a sunroom that will be used year round. Consider using tempered glass in your windows. This type of glass is also referred to as safety glass because it falls into small pieces if it breaks.

Step 2 – Planning the Electrical System

You will need to include a plan for the electrical system in your room. Determine the number of outlets you want to install and where you want to locate them. If you have no experience in electrical work, you will need to contact an electrician about having the work done. Be sure to do a lot of research in finding the best service person for the job. You will need an electrician that is qualified and that will give you the best price.

Step 3 – Building the Walls

Frame the walls to your sunroom. Allow for the windows and door in the framing system you build. Secure plywood to the exterior of the walls. If necessary, cut out the required space for the windows.

Step 4 – Securing the Windows and Door

Position the windows into the walls space. Be sure they sit properly. Use your drill and screws to secure the windows. Position the door into the door frame. Be sure it is sitting plumb and level. If necessary, insert shims to position the door. Use your drill and screws to secure the door into the frame.

Step 5 - Finishing the Exterior

Finish the exterior to your sunroom with siding. Be sure to use a siding product that works well with the style of your home. Secure the siding over the plywood.

Step 6 – Finishing the Interior

You will need to make sure that the electrical system is in place before you finish your new sunroom. Install insulation in the walls in order to save on energy costs and to allow you to use the space year round. Use a drill and screws to install the wallboard over the insulation. Make any necessary cuts in the wallboard for the outlets. Attach switch and outlet plates with a drill and screws. Secure any trim or molding you want to use in your room. Paint the wallboard with a color that works well in the space. Install the flooring you have chosen.
