1/3. London's housing market is booming, thanks to foreign investors buying property worth more than £100 billion - and as a result the luxury interior design industry is flourishing. This documentary follows three prestigious designers working for some of the capital's wealthiest clients. They include Joanna Wood, who has been designing houses for royal families and Hollywood film stars for 30 years, and Brian Wade, who has spent the past four-and-a-half years designing a seven-storey Knights-bridge townhouse, with furniture including a stingray-skin coffee table and a chandelier made from Hyde Park leaves dipped in gold.
