Very narrow stair gate needed, any ideas?

[ILoveSaturdays]

We have a very narrow staircase going upto the loft that is just 49 or 50cm wide. The narrowest stair gates I can find are 60cm.

Other parents must have had this problem before. Has anyone managed to find one? If not I'll have to resort to some DIY, which won't be pretty!

The flexible types go very narrow, although they are a pain to move. They are good if you don't intend to be going into the loft on a daily basis.

It's a while since I needed a stairgate, but isn't there one like a roller blind on its side, that pulls across?

Thanks for replies, the only roller style ones I can seee are very expensive. Not really an option sadly. I tihnk a trip to B&Q is coming up. Swearing will be involved.
