Serial renovators Andy and Gill are finally doing something for themselves. After years of buying and renovating homes to rent to others, they're ready to pick up a property for their own family. With one eye firmly on retirement, Andy is hoping for something work-free and turnkey. Gill feels that the only way to get what they want is to build it themselves. With an open-ended budget and a wish list full of high-end demands, to build or not to build will be the real question for Andy and Gill in Tenerife.
