Amazing Spaces Shed of the Year (Channel 4, 8pm)

ACCORDING to my other half, when I retire it will involve me investing in not just Shed of the Year, but a Shed of Every Year... I like to think I'm that popular in terms of access to the garden rather than the front room.

The man who is most guilty of over-using the term amazing is back, and so are the best examples of the structures that hundreds of people have entered in the contest to become one of 32 on presenter George Clarke's shortlist.

In the first episode of a new run, it's those that fall into the Unique and Historic categories that are under the spotlight. Among the places featured is a shed that can rotate 360 degrees so that it can follow the path of the sun, and another is so mobile – it's on top of an Austin pickup truck – that it can reach speeds of up to 90mph once it's on the road. Look out too for an Anglo Saxon long-house and a Vietnam war bunker in Staffordshire.

Wearsider Clarke rarely seems to be off our screens. In fact, how does he manage to fit in his TV presenting work with his regular job as an architect and developer?

"People assume that when you're a TV presenter, you don't have any other sort of job," he says. "But for me, first and foremost I'm an architect, a builder and a developer – that's what I love doing. All it means is I work all the time. On the train I'll do a batch of sketches and drawings for a scheme we're doing. Actually, that just goes to show how technology can effect something like that. I'll take a few photos of the sketches on my iPhone and send them back to the office so they can get cracking on what they've got to get done for the day."

Over the years, he has charted the construction of some incredible builds, from space-age homes that look like something from Star Trek, to the restoration of incredible historic houses.

"I do ping pong around Britain quite a lot," he says. "But you know what, I love it. For me, to be involved in so many builds all over Britain, is amazing."

One of the favourites to look out for tonight is the Tranquility Saloon, a Wild West-style log cabin in Aberdeenshire where the owner and his pals gather to drink whisky, play cards and listen to country and western music.

Celebrity MasterChef (BBC1, 8.30pm)

THE remaining three competitors' penultimate challenge is the toughest and most daunting of the competition – the Chef's Table, hosted by Michelin star chef Atul Kochhar at Benares, where they must master new techniques and unfamiliar ingredients to impress some of the best chefs in the UK. Judging the food are Cyrus Todiwala, Alyn Williams, Sabrina Ghayour, Romy Gill and Ed Baines. Back at headquarters, the finalists are tasked to present a faultless three-course meal for John Torode and Gregg Wallace – their last chance to prove that they have what it takes to be crowned champion. Last in the series.

BBC Proms 2016: David Bowie (BBC4, 10.15pm)
