Olaf Mason launches self-build workshops

The master carpenter behind the Grand Designs triangle house wants to help more self-builders

Grand Designs viewers were gripped as Olaf and Fritha Mason grappled with one of the trickiest self-build plots ever seen on the show. Sandwiched between a railway line, busy main road and a sewer, the resultant triangle house was a triumph of determination and craftsmanship.

The couple were navigating the taxing build while also undergoing fertility treatment (joyously, baby Lagertha made an appearance at the end of the show). Their openness, charm and tenacity — alongside Olaf’s exemplary carpentry skills — won them a place in the nation’s hearts.

Now, aspiring self-builders can learn from the grand designer himself, as Olaf launches a series of self-build workshops.

Self-build workshops

Taking place at TV’s most famous triangle house, located near Billingshurst, West Sussex, on Saturday 6 November 2021, the workshop is open to those at any stage of a self-build project.

The first event will take place in the Masons’ kitchen, but they will eventually be held on Olaf’s famous double-decker bus workshop – a drunken eBay purchase that the couple had a heck of a job manoeuvring into place on Grand Designs.
