Not all homes have a safe place where you can do that. And I even recall one story of a family that built a small shed in their front yard so they could store their bikes—not even for safety, but just the convenience of not needing to awkwardly drag the bikes up and down narrow stairs every dat—and the council forced them to remove it.
Apartments need to be required to have secure bike storage, and houses need to be allowed by right to build small bike sheds.
Edit: it was Ireland, not the UK. I guess because most of the stories about cycling I hear that aren't Australian are from the UK, my memory just lumped all of the British Isles together.
