If you are looking into options for your patio area, you will find many options are available. The first consideration has to be the cost of enclosing a patio as this will impact any decisions you make, although if you plan and design carefully you may find it is possible to do the job in incremental steps, so you still have use from the area whilst the plans are ongoing according to budget.
You may just want to create a private patio area away from the prying eyes of your neighbors where you can still be outdoors yet out of the view of the street or neighboring properties. Quite simply a board fence may be the easy answer, but as with all erections do check the local planning regulations for height or any other restrictions that will vary in each locality. This sort of solution is easy to manage yourself and a cost effective option.
Enclosed patios are increasingly popular because people want a shaded, bug free environment and like to bring the outside in. An additional benefit is you are free from the worry of sun damage. You could be upgrading your existing carport to give an additional foot print to your home and in this case pay extra consideration to the flooring as if you want an year round weather proofed room you will need to make sure your floor is appropriate.
If you are looking at how to enclose a patio the roof will be the first consideration. They can be self supporting canopy type roofs in glass, or you may prefer a gabled tiled insulated roof. Cheaper options could be to screen in a solid patio covers, or you can of course buy a complete sunroom in a kit form, it comes with everything you will need, the roof, walls, screens, windows and of course a door! Thinking of your garden decor will be important when choosing any design.
