Grand Designs Live (Channel 4, tonight, Thurs) will feature a house in Wales designed and built by Amazonails so everyone is encouraged to vote for it tonight in the Eco Home of the Year award.

Also during the daily week-long series Kevin McCloud will have just six days to build his own Grand Design, which he'll be building live every night.

With the countdown to the Olympics we've flown our armchairs to China a few times but in a new series: Wild China – Heart Of The Dragon (BBC Two,Sun) we travel the length and breadth of China to discover the full extent of its many wonders and to see how its unique wildlife interacts with one of the fastest-growing populations on Earth.

We start our journey in the humid sub-tropical climate of southern China. This is quintessential rural China – a landscape where peasants follow wooden ploughs pulled by their water buffaloes.

It may be pleasant to partake in armchair travelling but even watching from the sidelines can be a little uncomfortable in the company of Bear Grylls: Born Survivor (Channel 4, Sun). This week the survival expert is in the deadly jungles of Panama, facing waterfalls and mudslides, and aiming to catch supper with a bow and arrow. The searing heat and humidity of the jungle continue to test his courage and survival instincts to the limit. On the menu are termites and vine snakes.

If you prefer your danger contained in the kitchen then you'll welcome the return of Gordon Ramsay's F Word (Channel 4, Tues). As ever, the action takes place against the backdrop of a working kitchen staffed by Gordon and his kitchen brigade, but this time his staff are made up of celebrities and their friends and families.

For fictional drama Pushing Daisies (ITV 1, Sat) offers viewers weekend entertainment with a difference. When a dog breeder, who may have produced the perfect pooch, is found dead Ned and company try to figure out who exactly did the deed, especially after they learn that the deceased was a polygamist who left four grieving widows.

Real life is not always a rose garden as an observational documentary proves in Teen Mum High (BBC Two, Mon), which looks at life in a pupil referral unit for school-age girls who are either pregnant or have recently become a mum.

Teachers, specialist midwives and health workers help the students prepare for their labour and motherhood while they also study for SATs and GCSEs. Lessons range from English, maths and cookery to safe sex, birth plans, bottle feeding and baby baths.

And for a look at the other side of the debate Abortion – The Choice (BBC Two, Tues) asks the difficult questions. Whether or not to have an abortion might be the biggest decision a woman will ever make, and it's one they will live with for the rest of their lives. In the UK, more than 200,000 women every year choose to go ahead with the procedure but, 40 years after it was legalised in this country, it is a subject that continues to divide people.
