Piers Taylor and Cheryl Pilliner-Reeves hunt for ingenious micro-budget solutions to radically improve two homes that fall short of their owners' needs.

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. To maximise space, he designs clever storage which is joined to a bench-seat. Piers suggests using materials that are just £11 per square metre, but can they also find a low-cost solution for their floor? Cath and Rob are desperate to give their home a total facelift. Piers designs an eye-popping multi-coloured porch that would normally cost thousands - can they really get the materials for free?

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. Like many Victorian terraces, theirs is an awkward mix of levels and corridors - Cheryl's biggest challenge will be finding a way to connect it all for just £10k. Piers takes them to see a stunning home that flows across different levels, but the challenge then falls to Cheryl to create two bespoke staircases for just £600! Karen and David are total novices but are soon carrying out major building work. As their budget runs dry, they must get creative - will Karen really get her dream kitchen for just a few hundred pounds? Show less
