There are quite a few merits in starting a custom home project in summer or spring. The main benefit is that the weather would be quite good during these seasons. There would hardly be any rains and the day time would be quite longer than usual. This means that the amount of time spent on construction each day would be high. This in turn means that the project would progress faster and get completed soon. Of course, during summer, you need to think about how high the temperatures can go because you need to think of the safety of the laborers too. Working on outdoor construction in a very hot climate can be bad sometimes.
But, building a custom home in fall has its benefits too. If your goal is to go about the project in a low cost manner, then fall is the right time to start the project. You can save a lot on the labor cost as well as raw materials if you construct the home in the fall season. The reason for this is that fall is generally considered as an off-season for home construction. A lot of building contractors would be sitting idle during this time. So, when they get a project, they pounce upon it, even if they have to charge less.
