Vulnerable Technology: Round hut

Description
I built a round hut using palm thatch and mud walls to replace the damaged A-frame hut built a few months ago. The A frame hut was damaged due to torrential rain and poor design elements considering the wet conditions. The thatch had rotted in the part of the roof that gets shade. Moth larvae and mold grew and consumed the thatch in these places. The hut also tilted forward due to the back post being hammered in only 25 cm into the ground. So on returning to the property (it was cut off by flooded bridge) I began work on a new hut.
The new hut was positioned further into the open clearing to get more sunlight. A 3 meter diameter circle was scribed and 12 wooden posts were hammered into the ground, each 50 cm deep for a sturdier structure. Lintels were then tied to the top of the posts joining the posts together. A tripod ladder was made from poles lashed together at the top and a platform lashed to its frame. The roof poles were then attached to the top of the lintels and lashed together at the top to form a conical roof frame, 3 meters at the highest point. Loya cane was then tied on the eaves to act as support for the ends of the palm thatch.
700 palm fronds were then cut split and thatched onto the roof. The tripod ladder was used to climb up and thatch the roof from the inside. A cap was then made to put on the very top of the cone when the roof was almost finished.
A drainage moat was dug around the hut and the excavated soil was placed on the hut floor to raise its level above the damp ground. A deluge tested the hut’s water shedding abilities. Torrential rain fell while a fire was kept going inside the dry hut. The drainage moat flowed like a stream during the heavy rain event.
Loya cane was then harvested and woven between the posts. This formed a low wall. It was then daubed with mud inside and out. The clay from this was taken from the drainage moat. Rain falling into the moat meant that water didn’t need to be collected from the stream to mix the mud. This is another benefit of the drainage moat.
The low wall allows light and air into the hut. With a fire going in the central pit, mosquitoes are kept at bay. The central fire pit produces smoke and heat that will hopefully prevent moths laying eggs in the roof (the caterpillars of which eat thatch) and will prevent mold from growing. The hut will be used as an undercover work space for future projects.

A-frame hut after several weeks of rain and no upkeep The thatch at the back has been eaten by moth larvae and mold Time to build a new hut All the wood required Marking a 3 m diameter building site in a more sunny location (sunlight preserves thatch) Making in the first post hole First post Hole is 50 cm deep Each post is 1.5 m above ground (2 m long).
12 post in place Cutting loya cane Splitting cane Tying lintel on with cane This is called square lashing, used to strongly tie wood together at 90 degrees to each other "Wood henge" Making a tripod ladder Crossbar to stand on Roof pole.
Ends stick out about 30 cm over wall to form eaves Using ladder to tie top of roof Cane forms edge of eaves for first thatch to lay on Frame completed Collecting palm thatch with stone knife 100 fronds Splitting fronds Tying on thatch with cane strands Typical wet season.
Roof cap put in place last when it becomes to difficult to thatch from the inside Dissasembling ladder Smoke helps preserves thatch as it funnels up into the conical roof A drainage trench is essential in this climate Using the soil to build up the floor level Compacting soil Tree roots are a common problem Cut them with a sharp stone, not with your good axe. It may hit a stone and break the blade. Trench completed.
Torrential rain Roof works well Trench runs like a stream Cutting more cane Weaving cane through wall posts Keeping the wall low to let in light and air Mud from trench to daub the wall Digging a storage pond while getting more mud Water will now collect in storage pond (not for drinking but for working with e.g. mixing clay).

Hmm… are attempting to accumulate a ground of clay
it is possible you’ll perchance well perchance possibly additionally soundless originate lives and accumulate superb chat cash
I'm initiating to esteem this house he’s in needs to be essentially the most supreme for doing these items. Palm fronds and cane, but additionally enough woodland, correct clay, correct soil, a entire lot of water, loads to bellow and a entire lot of sunshine to grow issues. It's a bushcrafter's paradise.
Ya bought talents brother. Admire!
Fine work, thanks John
