Flooring - lino, altro (Coalville LE67)

Hello. I have just built an eco style shed on the base of an old greenhouse. The floor is made up of old mixed and broken bricks so looking to put some sort of floor down on top- looking for some lino, altro, rubber tiles etc. Doesn't have to be beautiful or new so if anyone is happy to gift some or may be taking up old kitchen, bathroom flooring would be just the thing. Many thanks
