50.This house was built by my grandfather in 1920. Now it's mine, and I live in it with my children. For a long time I dreamed of renovating it, but I didn't have time. However, last year I decided to start. I dropped other projects and devoted all my time to this one. If I had known how hard it would be, maybe I wouldn't have started. But now that the work is almost finished, I feel I have become a different person.
