If you currently have a carport that you want to convert into a garage, rest assured that it is a relatively easy transformation, provided your existing carport is in good condition. Structurally, a wooden carport is built about the same as a garage. All that is entailed in making a carport into a garage is simply adding sides, insulation and a door.
Examine the existing carport. You do not want any spans of more than 60 cm (2 feet) between wall studs in your carport. Start at one corner of the carport, measure 60 cm (2 foot) intervals along the walls. At each interval, you will install a 5 by 10 cm (2 x 4 inch) wall stud.
Cut the 5 x 10 cm (2 x 4 inch) boards to the length of your carport ceiling, and then begin installing the wall studs as follows. Stand the 5 x 10 cm (2 x 4 inch) boards upright at each 60 cm (2 foot) interval, and nail the top of the board into the roof edge and the bottom of the board into the floor of the carport. Continue in this manner all the way around the carport until the entire structure is framed.
Cut the sheets of plywood to proper length to fit on the outside walls of the carport. Lean the plywood against the walls you just framed in with boards, and nail them to the wooden frame. Butt each panel of plywood against the edge of the other pieces of plywood to prevent gaps, and continue until the entire carport is covered, save for the door opening.
Determine the type of garage door you are going to use, and then hire a professional door company install the door on your newly built garage. As some doors require a crane-like apparatus to install, it pays to have this part of the project carried out professionally.
Roll the insulation between the wall studs on the interior of the garage and staple into place. You now have your choice of finishing the garage. You can put siding on the outside or just paint it, and you could hang plasterboard inside the garage, or just leave it as is.
Installing aluminium cladding on the outside of your garage will ensure years of worry free use.
