If you're just dying to have a smart home, one way to get you started is a front door that works like a car door. It comes complete with a remote to unlock it, just like you would for your car.
The door features an odd décor that makes it stand apart from the rest and even a rubbery finish over the top of it. To ensure the best sound insulation possible, the door has a retractable guillotine.
The Brazilian design also has a built-in mailbox, hopefully the mailman can figure out exactly where it is though. As of now this is still a design, and not an actual product so there isn't any word on what something like this would cost.
