When thinking about building your new home, you do not want to pick home plans just because they are available, and if looking at pre-built homes, make sure they meet your needs and expectations. A home is not like a sweater that you can quit wearing if you outgrow it or decide it really is not what you want.
One of the first things you should do is make a list of features you want in your new home. More importantly, make a list of things to did not like about any place you may have lived in the past or seen as part of other houses. When looking over home plans, if those features exist talk about eliminating them or more to a different set of home plans.
Perhaps some of the things you did not like can be altered into things you want. Remember, you will probably be in the house for several years and there is no reason to settle for something you do not want. Once you have decided what you want in your new house, you can start looking at building lots.
The process of buying a building lot and home plans should be done simultaneously. The home plans should fit on the lot and the lot should be able to accommodate the plans. It could be difficult to find a lot to accommodate plans you already own and vice-versa.
There are many considerations involved in lot selection, as well, such as will low spots create wet areas that may cause flooding in parts of your home plans design. If part of your home plans involve areas built below grade, will adequate drainage be available to keep your home dry? If the answer is no, then you will want a different lot or different home plans.
