Liz and Sam have designer taste but don't have the budget to match. Their ground floor needs major remodelling with the front door opening into the middle of the sitting room and a lean-to in the kitchen that needs tearing down. Can Lucy and Harry come up with a layout to unlock the house's potential? The budget is tight but Liz and Sam have already coughed up £3000 for a sofa. It's a case of reusing, upcycling and thinking out of the box to bring this modern, stylish build in on budget.
