Enclosing a carport can make it possible to create an extra room in your home which is wonderful for any growing family. It's hard to plan for every scenario, so many families find themselves needing additional space at some point. Enclosing a carport can be a fantastic way of achieving this. As long as you have the right tools and materials available you should be able to easily enclose your carport. This is, however, a complicated project for which you will need to spend plenty of time planning.


The first thing that you need to do is prepare the carport to be enclosed. Start by cleaning the entire floor of the carport off. Also, if there is not already a concrete base in the carport, you will need to pour a solid concrete slab to support the new room. Start by making a box the size of the carport out of wooden boards and placing rebar in a grid inside the frame. The concrete can be poured into this form, and the wooden boards should be able to contain the concrete until it sets. Try to ensure that the concrete slab will sit at the same level as the rest of your home.

Build a Partial Wall

Now you need to measure the size of your carport and start building the frames for the walls. The walls can be built using the 2x4 boards with studs placed 16 inches apart. Place one board on the ground flat, frame the verticals into it, and frame another board flat against the top of the verticals. This can be built on the ground and then rotated up into place for the easiest installation. For long walls, make a series of such frames. You will also need to frame openings for any doors or windows you want to include.

At this time, you will want to know if you've going to have problems with water getting to the wood on the walls of your new carport. Make sure you have a plan for draining all rainwater to the appropriate location. If you have to, make a base to your walls out of concrete block or brick and mortar to ensure that the wood is not damaged later.

Fix the Frames

Use bolts to secure the frames to the concrete flooring and long screws to attach the existing roof to the new walls at the side of the carport.

Cover Walls

The exterior walls can be covered with plywood before you add the final exterior. There are a number of different types of wall covering including siding that you can use. Now is also the time to install doors and windows in the openings you left in the framing.

Electrics and Insulation

Get a qualified electrician to wire up any outlets in your new addition. You may be able to do this by yourself in some states, but make sure you're confident in your abilities before undertaking the project. You will also still need to get the work signed off by an electrician to ensure that everything is safe and that you won't be putting yourself in any danger after it's finished. Even if you are allowed to do the electrical work in your state, it doesn't mean you have to. If you don't feel confident enough to do this then you can hire a professional.

Insulation can be added between the wall studs to make the space much cheaper to heat and cool.

Add Finishing Touches

Drywall can now be fixed on the inside of the wall, and the floor covering of your choice can then be installed in the space. You can choose anything from tiles, wooden flooring, or carpet. Don't forget to prime and paint the walls as well before adding elements like light fixtures and furniture.
