It’s four months since the Lewelyn-Bowen’s turned their back on London for a new life in the country, but instead of rural tranquillity all they’ve had is dust, noise and builder stress.

Even Laurence is feeling uncharacteristically down. “I almost feel like someone has decided to pay me back for all those years of doing this to other people’s houses.”

As the building work reaches its dirtiest and noisiest stage, their 20 room house seems more like a war zone than a designer pad.

Tempers fray as Laurence reveals the colour for his groovy retro kitchen – guacamole. Jackie sees red (or green!) and throws a whole pot of it over the long-cuffed creative.

To lift spirits, Jackie decides to throw a summer party – a joint celebration of Jackie’s, Cecile and Hermione’s birthdays. However the party is double the size of an average wedding, and for a family living out of suitcases and cooking in a shoebox it’s one hell of an undertaking.

Everything is going to plan until with just one week to go, Gloucestershire is hit by the worst floods on record.

Will Jackie’s mammoth party have to take a rain check?
