George Clarke’s Amazing Spaces (Channel 4, 9pm)

WEARSIDE-BORN George Clarke just had to have his most over-used adjective in the title. Thankfully, George's enthusiasm isn't unfounded - the people featured have come up with some incredible projects, often on a very limited budget. Plus, it's nice to see somebody genuinely thrilled by what he's seeing when so many people these days appear to be somewhat jaded or cynical about certain things.

George is, of course, an architect by trade, and although he appears to be working on TV a lot, he does still find the time to shoehorn professional projects into his busy schedule.

"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. If only the housing industry was so efficient!"

George's filming work never stops either. While shooting the latest run of Amazing Spaces, he was simultaneously making the next two series of Restoration Man, a show that remains close to his heart thanks to the imagination and the bravery of the people whose projects he visits.

"These are people who are generally jumping into the unknown, taking on grade one or grade two listed buildings, many that have been abandoned for years. They do use a phrase sometimes that does make me laugh but is true, and they say, 'If I wasn't so naive, I wouldn't have taken on the project in the first place'. But the upside is that they're not paying a king's ransom for these buildings."

On Amazing Spaces, who can forget the couple from York who created a garden room using wooden pallets and second-hand windows? Or the artist who renovated a Futuro home that looks like something out of Star Trek?

This time, George travels to Macclesfield to meet a novice builder who is planning to spend just £300 on a Doctor Who-style multifunctional play den. He also visits a treehouse in Scotland and is impressed by a holiday lodge made entirely from glass in Italy's Dolomite mountains.

The Fall (BBC2, 9pm)

PAUL Spector is still a step or two ahead of Stella Gibson, the detective on his trail. But she suspects he's witnessed her confrontation with Burns in her hotel room. But what how will Burns react when she tells him?

As if the idea of Spector keeping tabs on her isn't disturbing enough, she then realises he's been visiting one of his surviving victims in hospital - but this fact allows her to set up a surveillance operation just as a body matching the description of Rose Stagg is discovered.

Crimewatch (BBC1, 9pm)

THE cases featured tonight include the disappearance of 14-year-old schoolgirl Charlene Downes from Blackpool 11 years ago. Her body has never been found, and her whereabouts remains a mystery - police hope that a new investigation will help to find her.
