Otto Cottage - Paul Marais. Maun, Botswana.

I appreciate that Paul acknowledges that his designs use already existing African technologies and that he did not 'create or discover' these methods. It is very important this, for truth and posterity. Work well done.

Who can put dislike on this wonderful video only sick person.Well done job people!!!❤❤❤

[@joshjeffrey2761]

excellent video, would love to see more examples of this architect. from Australia

[@Cool_boy258]

It seems to me that it would quickly take on the same temperature as outdoors. What temerature range can one expect inside the finished structure vs outside? How quickly does the temperature inside fluctuate? Thanks!

[@fmbida]

that's the beauty of it; in fact all African traditional construction methods have this quality. Heat is slowly accumulated throughout the day by the material and is slowly lost throughout the night, loss of heat is accumulation of cold; so the day is cool inside the building and the night is warm. Remember, our days and nights are almost equal throughout the year. So by the time all heat is lost, the sun has come up and vice-versa

[@ruedaricardo]

No, the walls are usually thicker than conventional brick walls and since the wall has a higher density, heat takes a lot to of time going from one side of the wall to the other: around 12 to 16 hours

what you mix in soil to make rammed earth house

[@mufpower]

Love it dear

[@juststill5932]

how quickly is dust formed indoors?

[@alanm03]

Does anyone know of builders in Botswana that I can contact about having work like this done?

[@Art20.30]

Good idea 👍👍

excellent vidio . please tall mi z ratio of z mixture

[@egaona69]

Robert Redford builder...?

[@leviwanyoike]

egaona69 ha haaa, I was wondering why he looks familiar 😂

[@raccasoko1709]

This is great.

[@jurylinfaschar3652]

What is the ratio pls.

[@emilioduarte7089]

between 5-15 cement, the best soil must have around 70% sand the rest its gravel and clay

[@kutupbear]

suitable for rainy northern climates?

[@emilioduarte7089]

it deppend on quantity of stabilazers like cement or lime . If youre not a hippye rsrs you could use 15 % cement, and aditives

[@amorfo9127]

Be carefull with asumptions here...build a home is a big/expensive/time consuming proyect so better found your percentages in solid test, I can recomend this book: "Diseño de adobes estabilizados con emulsión asfáltica, universidad de Cuenca" from Arteaga and Loja (free pdf online) is a thesis research about BTC (like rammed earth but in blocks), they run lab test for compression, flexion, absorption percentage, and "water footprint" very important data, your concern is in page 121: a BTC with 10% of cement, submerged in water for 10 min get a "water footprint" of 0.7 mm. So is not waterproof, that's why it is very common to "double wall" (not necessarily both of BTC/ramm.) so you can have rammed earth outside, proper water insulation in the middle+thermal insulation, and whatever you want for inside wall. Well, best luck and good readings!
