Can families live in tiny houses without driving each other mad?

An interesting interview at New Zealand's The Spinoff which features Jess Ellis talking about how she and her partner and two children live together happily in their 15 square metre home. Here's a snippet:
The best [aspect of parenting in a tiny house] is the relationship I have with my girls because I’m always right there. I’ve got way more time to spend with them, I’ve got freedom to do what I want to do but they’re right there. Another bonus: I hate chores. I’m not a fan at all. I have much less cleaning to do because I live in a tiny house. I can vacuum my whole house in three minutes! The worst is that we’re always together. Ha! I don’t necessarily think this is a tiny house thing but it’s certainly magnified in a tiny space.
