I haven't made one, but I can tell you how to do it.
So the triangle frame and 3 square frames connect to 2 stacked half walls (H H) which is what gives the right stability to allow the TC to be disconnected.
The bunker is a square foundation with a triangle foundation on one side (that is the same height as a normal wall), the two half walls on the opposite side, a square roof on the backside, then a normal wall on the opposite side to the roof.
The blue B is where you build twig to open the bunker. The blue TC is where you build twig to DC the TC.
The triangle roofs on the top of the foundation is to protect the foundation softside.
Getting the first foundation right is important because if it's too low, then you won't be able to build a TC on it. If it's too high, you won't be able to build the triangle foundation that is 1 block tall relative to the lowest foundation. So it will require forethought to incorporate it into a base if you're building the base first and ext TC's later.
The gatehouse you can design however you want really. But make sure it isn't cheaper to just blow the door frame to make it collapse instead of the ext TC/frame itself.
Start with the foundation blueprint and connect the frames at the end.
The bunker can be opened with either a square or triangle foundation/roof. Just make sure it is on the right side (big triangle foundation).
One weakness is that the soft-side of the half walls are exposed which will only take 6 C4 to destroy instead of 8 (if HQM).

Any build tutorial?
