Jason and his Finnish wife Riikka have lived in many homes in Torquay, but never one that truly felt like home. The battle to get their dream home becomes the longest build ever featured. They don't want a big house, but one which perfectly fits their needs, so having bought a breathtaking plot with sea views, they get to work.

They are building an ambitious modern home which hopes to take full advantage of the sea views. The principal materials are glass and steel but as architect Piers Taylor points out, they are two of the least forgiving materials for any self-builder. Kieran Long is shocked at how complicated they have made their home. The entrance is confusing and in a home dominated by glass, they have chosen fixed panes rather than ones that open. He takes them to see one of the finest modernist homes in Britain to try and prove that adding simplicity is the key to their home not complexity.

Piers is on a mission to get them embrace open-plan living, which will make the most of the view. He reveals how to disguise a kitchen so that it doesn't dominate a living area. Meanwhile, Riikka is keen to furnish her home in a Scandinavian style, so Kieran takes them to Denmark to understand the roots of that movement and shows it is about clever choices, not spending money. In this mammoth build, Jason and Riikka battle winter storms, injury and countless setbacks, but will they get their dream home for under £100k? Show less
