Our house is 50-some years old and we love it. It has character and charm. It has mature trees and a good sized yard. It also has cracking concrete and an ancient boiler. It has old tile and wood paneling. It has a beige, no maybe more like rust-colored, bath tub. But that's life. Things get old. You take the old with the ugly and mix it together into something that is satisfying and much more interesting than what you'd buy new off the shelf at your local big box store.
One of the more interesting features of our back yard is the old incinerator. As legend has it (okay, our sweet old neighbors next door told us), each home was originally built with one of these incinerators, used for burning trash and debris. Over the years, city regulations changed and burning became unlawful, so many of these structures were torn down. But not ours. Someone was resourceful enough to turn ours into a birdbath.
designing may take a bit more thought and creativity, but I think we will be better for it. And as I like to think of it, you're making history and telling a story all at the same time.
