Changes can certainly be made during the construction process, but depending on the nature of the change, it may cause added expense or delays. In general, things like moving the position of a window are not a problem. However, when it comes to moving a load-bearing wall or changing the size of the home, it will be more complicated. Also, the difficulty of making a change depends on how far along the project is. For example, changing the type of finish at the last minute would add more to the cost of the project than making that change early on. That being said, our clients routinely request changes during the building process, so we are used to working them to make sure that they are satisfied with the finished home.
