The front door

Why do TK and Carlos have a sliding barn door as a front door? It is so easy to break through and when Iris came to talk about divorce she left and the door partially slid back open in shot when she left. It's glass slats. I live in a city condo and my door would take a literal axe to get through. I'm watching the series again and it's such a simple thing that annoys me. Anyone else?
