Amazing Spaces Winter Wonderland, C4, 8pm

ARCHITECT George Clarke and master craftsman Will Hardie embark on a road trip to explore the ingenious small-space wonders hidden away among the snowy peaks of the Swiss, French and Italian Alps. They start out from an observation point 12,000ft above sea level, then visit a secret ski lodge disguised as a boulder, a treehouse resembling a giant acorn and a Swiss cabin made almost entirely from concrete. Other highlights include a hamlet made from eight 200-year-old chalets collected from all over the Alps and a mountaintop restaurant resembling a spaceship.

Billy Connolly’s Ultimate World Tour, STV, 9pm

LAST year ITV brought us the documentary Billy Connolly And Me: A Celebration, which stirred up mixed emotions for fans. On the one hand, it was great to see The Big Yin on television, but on the other it felt so much like an obituary that a few viewers felt moved to take to social media to ask if they had missed some sad news. So, many people will be breathing a sigh of relief to learn that although this new documentary finds Billy reflecting on his previous TV travels, it also features some upbeat new footage of the comedian exploring his current home of Florida. As he travels around the Florida Keys, Everglades and Miami, he encounters alligators, Cuban domino players, a poet and his wife Pamela, who joins him for a post-fishing trip meal.

This Is My Song, BBC1, 8pm

NOT everyone who wants to make a record is looking to become a pop star. Some people just want to create a track that means something to them, which is where this two-part special comes in. It gives ordinary people the chance to enter a professional recording studio and record a song with the help of singer and producer Naughty Boy, Sister Bliss from Faithless and leading producer Andrew Hunt, as well as a team of vocal coaches. Those stepping into the booth include 72-year-old Yorkshire crooner Ronnie and his 23-year-old grandson Jordan, who want a recording they can treasure for years to come. Others stepping up to the mic include 13-year-old Jasmine, who suffers from anxiety and wants to record a song that has helped her through tough times.
