Charlie meets Mark and Amanda Hepden who are self-building a cottage in Stony Stratford. Amanda is a sales co-ordinator and Mark a carpenter who takes on a lot of the work. If they complete it for £145,000, they could have a £75,000 profit to reinvest.
The plot's tight, as is their budget - and a supplier goes bust leaving them thousands down. As they invest more time and money, Charlie wonders whether they are falling permanently in love with what's supposed to be a halfway home. To prove that big isn't always best, Charlie arranges a visit another tiny house that's perfectly formed.
