Could really do with sorting some secure bike storage ASAP. The Asgard Centurion 6 bike store looked to fit the bill perfectly but when I went to buy one last month it was a 14-16 week wait!

Have been looking around but cannot see anything that feels as secure or comes disassembled as I want to install it in one of the barns.

Only other options seems to be build a quick concrete block bunker and get some steel doors welded up but that seems a bit extreme and a lot more hassle than assembling a steel shed.

One I am looking at, I am sure it was £200 less last month too! https://www.asgardsss.co.uk/high-security-sheds/cycle-maintenance-shed

It probably was. Galvanised sheet is like rocking horse poo at the moment and has easily doubled in price in the last couple of months

Just watched the video on the link in your post.
What a pointless demonstration of it protecting against an intruder.
Oh, lets get a big brute to kick it repeatedly then try to jemmy it open with the worlds smallest crowbar. Even the scrotiest of scrotes goes better equipped than that.
I’d go for the block bunker and steel doors route if it was me

Best alternative I have seen is these: https://www.portablespace.co.uk/product/3m-x-21m-flatpacked-store-powder-coated

Local garden centre has them for the same if not slightly less. 3x2m. Have 2 Yale locks but nothing at the top and bottom, I guess I could add something.

Blockwork still looking attractive but struggling to find the time to get through a massive list of jobs, especially with all this rain. Looking at using concrete lintels for the roof.

Won’t be the same quality and price doesn’t include a base etc. but surprisingly Argos do metal sheds. Might be worth a look

I got a local agricultural fabricator to build one to my specs. Similar price, better suited to how I used it and sized for what I wanted to put in it.
