Charlie Dimmock and Harry and David Rich create a colourful, exotic sculpture garden in a home in Llandrindod Wells for Lynn and Bill.

Retired couple David and Joyce's back garden in their home outside Gloucester looks more like an allotment than a garden. David is a dedicated vegetable grower and for Joyce, that means there's nowhere shady or pretty to sit and enjoy the garden. Meanwhile, David's increasing back and knee problems mean he is struggling to keep up its maintenance. Charlie Dimmock and Harry and David Rich set out to make the garden both prettier and more user friendly, all within a £3,000 budget.
