Adding a two car carport to your home can increase its value and make it even more practical and useful. Plan on building the two car carport against an existing wall in your house because it will be able to lean against it.

A carport will help to protect your car from the elements and will also provide your back yard with some extra shade. If done properly then the carport will be an integral part of your home.

Step 1 - Planning

First you should give some consideration to the location of your carport. This will be much easier if you are building the structure leaning against an existing wall on your home. Choose which external wall is best suited to having a carport. This will depend on choosing a location which is convenient and practical.

Step 2 - Marking

Now mark the ground where you will be putting the foundations, start by measuring away 10' from the wall you're building from. This will give you enough space to house 2 cars.

While you are at this mark the position of the ledger board which will be positioned and fixed onto the external wall of your home to support the rest of the structure.

Step 3 - Foundations

Dig the holes that you have marked for the foundations so that they are at least 35 inches deep and a minimum of 12 inches wide.

Each hole then needs to be filled up with wet concrete, the steel mounting brackets can then be pressed into the wet concrete before it has chance to set. Adjust the height of the brackets so that they are all even and equal.

Then you should leave the concreate alone so that it has chance to dry. Never attempt to continue construction until the concrete is completely dry.

Step 4 - Ledger Board

The ledger board should now be fixed onto the external wall in your home. This should be bolted onto the wall so that it's secure and won't move.

Step 4 - Joists

Attach the joist hangers onto the ledger board so that the joists can be positioned across the structure. Work out how many joists are required to make the roof and structure as strong as possible.

Step 5 - Covering the Walls

The walls now need to be covered in the plywood sheeting. Ensure that you are using external grade plywood so that this won't seperate in damp conditions. Plywood is an important step no matter what wall finish you are using.

Step 6 - Roof

The roof can either be pitched or flat depending on your preferences. Most people will choose to install a flat roof which is made from corrogated plastic. This will need to be fixed onto the rafters in your carport. Alternatively the roof can be covered in plywood and then roofing felt. Optional extras can include adding doors and enclosing the sides of the carport.
