Your Garden Made Perfect (BBC2, 8pm)

HOMEOWNERS get the chance to see what two designs will look like before they pick their favourite.

He’s travelling along the wild and rugged west and north coasts of Ireland, making a stop at the Mizen bridge, suspended 45 metres above sea level.

Sadly, it turns out that Stephen’s health kick isn’t all that healthy, Cass’s student house has no students in it, and Andrew thinks Geoff’s new partner may have an ulterior motive.
