Not really a channel dedicated to it but there seem to be a lot of episodes of secret of the castle on YouTube. There was a castle being built using period accurate techniques and they filmed a documentary while they were constructing it.

David Macaulay wrote a series of illustrated books about the construction of various types of historical buildings such as a castle, a cathedral, the pyramids and a few others. The first, Castle was made into a PBS documentary but I'm not sure if any others made the jump.

Edit: Looks like Cathedral, Pyramid, Roman City and Mill were also made into documentaries.

Absolute History has a ton of their content on YouTube. It's a BBC show following a historian and two archaeologists as they live like they're in that time period.

They have a 1300s one, a 1500s one, and a Victorian era one, so probably 17-1800s

I've only watched one video from this channel but seems to fit the description

So are you going to build a castle or something?

Look out for documentations about Guédelon, you'll probably like it.
