You're reaching into an area that has been very seldom broached in public. There is no ideal home and I know this for a fact now. In 2002 I designed and built my ideal home but once I started living in it I realized it wasn't ideal. Not just one thing was wrong with it but many, and of course at that stage of the game it was too late to fix them. My wife said I am never satisfied and she's right. You could design your dream home and build it but you too will change, like I did, and your dreamhome will not be that anymore. It might take you longer than it did for me but it will happen. For me it happened kinda fast cause by the time my house was ready to move in I had already become educated, by designing homes for other people in the interim - and learning about things, that my home seemed somewhat outdated and inefficent - I had quite naturally, changed. sigh
An ideal home can only exist in the mind of the beholder for a brief period of time and as the world turns so do the ideas and thoughts in a persons mind and they will long for something more adaptable to what they want, now, not yesterday.
