Pre-Fab homes are becoming more and more popular in today's age due to people's desire for "Instant Gratification" in their lives. I have to say that this option is tempting to me too, as I tend to like things that come easily to me, but I like to choose my own finishes and design. Companies are realizing this now, so most pre-fab homes can be customized, which gives you more control over the finished product.
Beautiful Pre-Fab options are available from many different companies. I like this one, which is located on Vashon Island in Washington. I am not affiliated with this company, I just liked their designs. I provided a link below to their website if you want to find out more.
