Did anyone catch this weeks grand designs?

A lighthouse project that I’ve just watched on catch up. Unbelievably ambitious feet of design and engineering. This guy had a very outlandish dream of building a house of epic proportions and that dream proved to be so difficult to achieve he pretty much lost everything, £5m sunk in to the site, ran out of cash, left with a shell he can’t finance to finish, needs another £2m to finish it and lost his family over the strain of the debt and project. Pretty much bankrupt.

He did build an second house on site worth c. £2m so has somewhere to live and it’s stunning

But what blind craziness drives a person to over reach in such a significant way?

If you haven’t seen it, it’s worth a watch
