Garden Rescue S06E28 - Oldham

Nigel and Deborah live in Oldham. Having spent the last year renovating their home with a cool mid-century interior, it's now time to tackle the garden. They want it to reflect their home, but with Nigel loving concrete and rusty metal, it has to have an industrial feel. They are open to anything, with the only criteria being that the garden mustn't be normal! Can Charlie and the Rich brothers transform this uninspiring back lawn into a 1970s space with an industrial edge on a budget of £5,000?
