I live in the house that my father built for the family in 1955.
Modifying it in my parents' lifetime would have been as popular as a fart in a spacesuit of course, so I didn't.
I have recently renovated it and added a solarium (my new office).
I designed it, Glazing Vision built it, Building-Control approved it, and I now spend every minute of the waking day in it.
