I've always lived in houses with an upstairs. Our house is big. It was bought when all of them lived at home and I am still here. At present only one of my children is still living at home but when she leaves I will be selling up and buying something completely different.
We stayed in an open plan lodge for half term. It was fantastic. I want one and I want it NOW. No stairs.. oh joy :) But not only that you could watch TV and keep the 'chef/cook' company. It was lovely.
What about you? What's your dream home ??
