I never imagined that I would live in a house like Casa Tuscania. In fact, it wasn’t until I saw it for the first time, in the light of the morning, that I realized it was my dream house. Just a couple of years before, I had left my father and brother’s firm to start my own more modern architecture practice in San Salvador. We have broken down walls, literally and figuratively, to create the Swiss Family Robinson–like tree house we call home. It’s pretty isolated here, outside of San Salvador, and those factors were important in deciding where to build and how to raise our two daughters, Pilar, 15, and Jimena, 4, in a natural environment.
