An addition of a second storey to your house can be a great idea as you will be able to use the extra space for the things you always wanted to do. You can turn it into a library, a study, a playroom or anything you want. However, there are a few things that you have to make sure before you could proceed with the job any further. The most important thing is the permit.
It is important that you get the permission for the addition according to the construction codes. You may have to face legal hassles if they are not abided by or breached. Then, the foundation of the house has to be assessed by a professional who would tell if you if the foundation is strong enough to support the second storey. Other important factors to consider are the ventilations, the area of the stairs and most importantly the materials. Then, finding a good contractor will also be crucial in this regard.
