Keeping my bike safe outside in south east London
I have just moved into a small flat with a parking space, and I cycle to work (hence how I could afford a deposit, sorry tfl). If I get permission from the freeholder, is it a good idea to build a weighted bike box or shed on my parking space? I know it can't be permanent as I only have a leasehold, so I can't do any structural damage like drill in a bike rack...
Any recommendations for a safe way to store my bike without my lugging it into my hallway every day?
Recommendations welcome!
