Currently living in a shared house with friends, ambitious young couple Tom and Zoe are desperate to move into their first home together. Not wanting to settle for the uninspiring homes that their small budget would buy them in Cambridgeshire, they have bravely opted to buy a plot of land on a housing estate and build their own. Planning permission dictates a relatively conventional home on the outside but they have plans to make it spectacular on the inside.

After living their whole lives in conventional houses with every modern convenience, Jane and Andy have bought a plot on an eco-community in West Wales where they can build their own home and live a self-sufficient lifestyle. As passionate environmentalists, they intend to build the house with locally sourced materials and to demonstrate that it is possible to build an environmentally friendly and comfortable house.

Newly-engaged couple Mary and Justin are desperate to build a life together in rural Devon where they and generations of both of their families are from. But with house prices soaring, the market for first-time buyers is desperately grim. They are left with one option - if they want to stay where they know and love, they need to build their own house.
