There are many projects that you can undertake as a homeowner, but a major one is to finish your attic.
While some homeowners might feel overwhelmed at the thought of such a large job, it can be a great addition to your home and give you a lot more room for either a growing family or just a nice place to put your visiting in-laws.
Of course, a large project like that does require a lot of forethought and planning. The first questions to ask yourself should be whether or not you can afford it, how the work should be done, and if you can get the necessary permits to do the job. It could be a good idea to involve a contractor in the planning stages since he would have the experience of what could be involved.
One major issue that finished attics can run into is that of climate control. Since insulation might be separating your home from the attic, and with hot air rising, you would do well to have a separate thermostat for the attic. This will enable you to keep the attic at a comfortable temperature.
