Country music legend Daniel O’Donnell and his wife Majella go head to head with architect Dermot Bannon in brand new Room to Improve, this Sunday on RTÉ One at 9:30pm.

While Majella is keen to upgrade her home, her husband thinks that very little needs to be changed. You can image what Dermot has to say about that! Check out a preview of Sunday's episode below.

How will Ireland's favourite architect fare as he attempts to reconfigure the couple's beloved home in Kincasslagh, west Donegal?

Well, he may have some trouble convincing Daniel of anything. The singer is far more interested in adding an ensuite bathroom to every bedroom than he is with oak finishes and viewing platforms.

And don't even get him started on secret doors.

Always a fan of light and big windows, Dermot impresses his clients with an enlarged double height south-facing window. However, they’re not so taken with his vision of wooden floors and a huge exterior floating deck.

As a massive consignment of triple glazed windows arrives on site, the concerted efforts of nine fitters are nothing compared to Dermot’s challenge of placating his feistiest and most single-minded clients yet.
