Hey Davin, thanks for the videos. Man, Evan's flying along.


Watched 'movie_043583.mp4' (catchy name, by the way!). Left with some questions/comments.

I feel kinda like I'm only getting half of a conversation, or maybe I'm just missing something obvious... but, what is the purpose of the topmost hip roof? Is there some problem with existing structures/designs that it is addressing? Why do we need some many roofs over the same area? At first glance I assumed it was to allow windows underneath the overhang, but that's clearly not the case in this plan...

It does look like a pretty dark structure; if the wing wall areas are roofed over, a round door added to the outside, and then there is a wall with door between them and the main room... drastic reduction in light inside the main room, no? Could those main room/wingroom walls be made mostly transparent, to maximize light and apparent openness?

Does 'capping wall' imply anything specific in your videos?

'Capping wall' is what I call the wall that has insulation, and divides the interior space(s) from the exterior space(s). Paul's current designs have two each. Current wofatis, like Allerton Abbey and Wofati 0.8, have these walls at 'front' and 'back'. These walls are major components of the facades.

Continuing to talk about the current/existing wofatis, Wofati 0.8 has exposed wing walls (the wing walls are exposed to the weather in all directions). I propose that future wofati designs incorporate a roof structure for each pair of wing walls. Therefore, I propose a shed roof over each pair of wing walls in 'front' and 'back'. Furthermore, hip roof structure is added above, in center overlapping both shed roofs. A flat roof resides one moisture barrier below the hip roof. All roof structures hold dry sub soils to structure the wood and soil partnership.

Please note: My proposal involves a oval opening, but not a door fitting that profile.

I agree with the need for transparency in the 'capping walls'.

Hi Davin, thanks for your videos, they provide a great real-life perspective into what's going on at the ant village!

The only problem I had was hearing your interviewees outdoors. I don't know much about video making, but thought there should be a cheap way to record audio on another smartphone that stays with the person you're filming. And I found these little tutorials that you may find interesting for your future videos:
Use a Smartphone as a wireless mic
DIY microphone for under $20

Thanks again and keep the good work!

It's good to see a design professional working on the wofati concept, bringing other ideas to bear that may not have occurred to the initial developers. I do have thoughts on some of these topics. In no particular order, the concept of turning the rectangular space to expose the corners and have interior angles maximizing contact with the thermal mass is sound. It potentially gives more interior volume with less weather exposure, while still letting light reach directly to every part of the interior. I don't understand the value of making two straight "tunnel" exits from each corner; you would get significantly more light yet not much more heat loss by letting light in from all angles at the corner.

The plan of covering the wing walls with roofs, and only a few oval openings, would turn the interior into a cave and for many people this would cause claustrophobia or at least much less comfort and enjoyability. The wofati is not supposed to be just a survival shelter but an attractive place to live. If it is not attractive in terms of internal comfort to average people, it will not see long use. I get the impression that Paul wants to get to a structure that is so close to invisible that there are no straight line openings to the exterior. This is fine, but keep livability in mind. The rough primitive interior look is not inherent to the concept of a wofati; one could be finished to look quite "civilized" on the inside without altering its principles.

Why does a wofati need any hip or shed roofs over its internal flat roof/ceiling? The mounded earth (kept dry for insulation/mass)if sloped correctly on top will do the same thing when covered with a waterproof membrane as a wooden roof structure would do, at much less cost.

Finally, it was painful to see a few ants discuss layout of their small structures and orienting windows every way but south. Proving the feasibility of a thermal flywheel concept is great, but if you plan to live in a structure, it only makes sense to build in multiple routes to warmth and comfort. Also, do not minimize the psychological importance of direct sunlight inside your dwelling in the cold winter months. I grew up in a house designed by my mother in the late 1950's which had south-facing windows and clerestories protected by overhangs, and the feeling of basking in the midwinter sunlight in the middle of the living room floor has stayed with me ever since.

My goal is to achieve a Wofati 1.0 plan/model.

LIGHT: The amount of natural lighting may suffer in the early designs. I agree with the need for natural lighting, but I believe a shallow porch and patio may allow quality task light. (Thanks for adding your childhood memory of basking in the sun. It is always wonderful to hear of such lasting architectural experiences.) I may lack a true understanding of human needs for winter sun light. I am not at wheaton labs right now and I have never spent a winter above the 32nd degree of latitude. (I basked in the sun on my town square yesterday at 30 degrees latitude.)

OPEN CORNER DESIGN: I was thinking the light would be more plentiful throughout the day depending to the site and orientation. (Light reaching the interior, as well as reaching the porch/patios.) The desired thermal inertia of the interior would not be effected by these double tunnels on opposing corners.

ROOF SLOPE: A design MUST is the hobbit-like round header of an entrance. Another design MUST is making the construction "Amateur Friendly". Thus, as I applied the layers up from the finished floor (F.F.=0'-0") in a 3D model, I found that - had I used a flat roof with sloping soil masses overhead, the construction would (1.) require a more in-depth structural analysis, (2.) expend more wood members, (3.) limit interior ceiling height(s), and (4.) require more experienced builders. (That design, once made, would be less forgiving.) Instead, the 3D model I have made as of now has three shed roofs. I believe the design is a simple concept capable by many.

Please tell me what you think about the design posts that follow.
THANK YOU!
