Last Sunday night's Room to Improve saw Dermot face one of his most challenging clients yet as Christine had a list of demands about ten pages long and the budget to pay for about a tenth of it.

This week's episode, however, it's Dermot who is very much the diva as you will see in the preview clip below.

He arrives at the small seaside town of Portrane in North County Dublin to embark on his next project but not before taking some downtime to fulfill an architectural dream of his - to visit Lambay Island, home of Lambay Castle designed by Sir Edwin Lutyens, a hero of his.

However, things don't go his way when he discovers that the island is closed to public access and he will have to ‘make do’ viewing from afar, and Dermot is not a happy fella, to say the least.

Not even a few seals will cheer him up.

Watch some of the clip below while you can see it in full over on the RTÉ Player.

Catch Room to Improve this Sunday on RTÉ One at 9.30pm.
