Ground level bases: defenses

I made some snapshots and two videos about how to protect your base from hostile mobs.

First, the videos (I use brick blocks because the map is a stone-based flat map, to avoid passive mobs spawning):

Murder holes:


I got this concept from Paulosoaresjr, you can see the link to his channel to the left. To build a murder holes protected base, the inside must be 1 block lower than the outside, and the rest is to leave an uncovered hole. If you were to leave a hole one block up instead (and not making the inside 1 block lower than the outside) you would be vulnerable to skeleton's arrows.

Spider's bane:


This one I found by experience: a spider can't attack to something under itself, and it has a 2x2 blocks base (and 1 up), so this shows what to do before getting out of your house in the morning: check the roof for spiders ^^.

Now, some more defenses against stuff... like a lava pit (with a piston middle jump point), a cacti perimeter and what I call "the house's hat", something that, believe it or not, prevents spiders to get to the top of the house:

Lava Pit:


Cacti perimeter:


"House Hat" (be advised that undeads might find protection from sunlight under its shadow, so it works best with the murder holes):
