The £100K House: Tricks of the Trade

In Sutton Coldfield, West Midlands, they come to the aid of builder Lee, who added an extension to his suburban semi. However, two years later the ground floor is half built, and his partner Jaimelee and their three children are left living in a building site. Meanwhile, Suzanne, Antonio and toddler Sophia struggle with the awkward layout of their west London flat, giving Gurmeet the challenge of rethinking it.

In the East Riding of Yorkshire, Chris and Claire need a solution to a problem with privacy in their quirky former Post Office home. The floor-to-ceiling shop windows mean they are overlooked by passers-by, but Robert Jamison has a radical proposal. Mark and Linda live in a narrow house which is too dark and feels too small, so Piers Taylor reveals tricks that can transform it into a brighter home.

Lisa and her son live in a former butcher shop in Derbyshire, and Piers Taylor faces a huge challenge when he tries to help transform it on a bugdet of just £8,000. There is no kitchen at all, and he must use cost saving methods to inject colour into the house. Meanwhile, in Shropshire, Julie and Richard have fallen out of love with their home, which is a mismatch of styles and eras. Meredith Bowles must find changes that will make the biggest difference, and takes inspiration from tricks used in a 1960s property.

Piers Taylor helps to transform a small three-bedroom house in West London for couple Skye and Matt, who have four children and a fifth on the way. He must find low cost ways to use every inch of their home, and comes up with a series of sleeping platforms that could utilise wasted space in the loft. Meanwhile, Adam Khan finds an ingenious way of a splitting an ordinary home into two for Mary and her adult son Luke, who cannot afford a place of his own as a consequence of rising house prices.

Cath and Rob and their three children have outgrown their ex-council house in Warwick. Their chaotic ground floor is a series of dark and miserable rooms, while upstairs they have three cramped bedrooms. Unable to move, they are planning a typical two-storey extension. Piers's suggestion is to ditch their ambitious extension and instead build a simpler one. Karen and David are desperate to fall in love with their home in Ipswich, but it's hard. Karen loves baking but her kitchen is so small she makes cakes in the cellar, and meanwhile David wants a space he can work from home in.

Adam was desperate to remain living in London, but with house prices shooting up, the choice of homes on offer was small, as were the homes themselves. Adam bought one of the thinnest homes in the country. At just six foot wide in places, this former alleyway was dark and barely habitable - can Katy possibly find a way to unlock its potential? In Walsall, Hardeep and Rupinder have plenty of room for their family, but it's in all the wrong places. They regularly have their extended family over but Rupinder does all the cooking in a tiny kitchen and a ramshackle lean-to which has seen better days. Piers designs them the ultimate sociable space and encourages them to orientate their home on the garden.
