I also go for that idea of building my house so I would do my own design. However, constructing my own house is very stressful that I cannot imagine the construction to take 6 to 10 months that I would be on my toes. I would rather buy an old house and have it refurbished. That is an easier choice.Personally I would prefer building my own house for so many reasons. one of the reason being that it will be built will it a very good material and to my own taste.
