Self-build timber frame house – anyone done it?

Looking at going down the route of buying a plot of land with planning permission and building (more likely getting built) a timber frame house.

Been looking at suppliers like Dan-Wood; Potton; MBC; Scandia-Hus to get a feel for what is out there and the different options.

Have had some initial discussion with a couple of them to get a sense of what they’re like etc.

Thought I’d ask if anyone here has been down that road – or considered it and then done something else etc.

I know Potton have a show home centre so am planning a trip there at some point.

Any experiences would be helpful.

Cheers
