Interior Design Masters series 5 winner revealed

Roisin Quinn has won the fifth series of Interior Design Masters with Alan Carr, landing a homeware collection with La Redoute.

IDM, judged by interiors guru Michelle Ogundehin, follows 10 novice designers looking for their big break in the world of commercial interior design. Working individually and in teams, they're given free rein to redesign spaces in line with the client's brief, and each week an unlucky designer is sent home.

Series four was won by Monika Charchula, a furniture artist from Nottingham, who won a contract to redesign a top cocktail bar in central London. 'The show is such a springboard – that’s what I love about it,' says host Alan Carr. 'Banjo Beale has his own show, Micaela Sharp, Peter Irvine and Siobhan Murphy do presenting. Molly Coath and Fran Lee have worked with the amazing Matthew Williamson, and I saw a massive billboard advertising Paul Moneypenny’s new wallpaper range – felt like such a proud dad. This show can change your life.'

Projects for series five included turning former nuns' cells into B&Bs, remodelling holiday lodges at Blenheim Palace and transforming Wembley dressing rooms. Michelle also welcomed guest judges from the world of interior design including Abigail Ahern, Kelly Hoppen, Mary Portas, Jonathan Adler and House Beautiful columnist Sophie Robinson.

Roisin has collaborated with La Redoute on a one-of-a-kind homeware collection, marking the first time a brand collaboration has been the show's prize.
