Well until the next recyclable good rubbish collection and then we fill it up again 🤣
Seriously though, it is called a double garage, has a 14 foot wide electric sectional door, and 22 foot deep. So it isn't that bad for UK (low) standards. But I couldn't put two cars in it side by side. And the height is challenged as well.
I don't think I'll ever understand the way they build houses in the UK, most are just so small, too close to each other, and bedrooms the size you can just spread your arms (or legs 🤣) and touch both walls. Be glad when these lockdowns are finished so we can move out. As I'm getting kicked out in June 2021 anyway due to Brexit...
