Plan to build my house - after reading Don't Tell Me What To Do

I have never bought or built any own house, but I would like to describe my process plan how to buy an own house. If I have a child, I will buy the own house when the child enroll at an elementary school to avoid him/her from transferring the school. In order to decide a layout of house, I would like to visit many houses what types of layout there are and what layout/function is convenience for my life style. Also, we should confirm what construction/material have the quality to last long and how maintenance is needed. From seeing many houses, I will get many useful ideas.

I think it is very important to imagine not only current but also future life style and to find a best solution with satisfaction at that timing. My thought mentioned above is caused by my experience. When I bought my current car, I checked many many cars at car park etc to know what internal/external design I really like because I thought it was very important to like the look of the car to ride for many years. Now, over 10 years passed after I bought my current car and I still like it.

When a rough idea of layout/function is made, I will ask some home builders for quotation. Maybe the quotations will exceed our budget, so I will review again what part we can handmade or eliminate and negotiate the home builder to do markdowns.
