Building is actually one of the few things we should trust Barto at.
I love all those innovations, but right now, I think there could be more... in a decade, all those "innovations" could be called out-dated. It's a bit wrong timing imo. I'd seriously think about investing more and making the "sun-screen" from solar panels. Would make the electricity bill a nice zero with a potential of making a small profit each year. It's a sunny place.
