That's what I plan to build, but the house will have to be bigger one. Like 8-10 rooms (medium size rooms).
But the good size is that I built 6 figure monthly profit online business, so I can finance it.
And my biggest requirement is that the house (in general) has to last for few generations (few renovations are OK), I don't want to waste tons of money on something that will stand for only 50 years and go down.
