primary school of three class units with a great local team!
measuring and concrete, pillars and trusses in prefabrication,straw-light-clay and windows.
students of Witwatersrand University for engineering are analyzing our construction method with light clay.
a small team of volunteers from the University of Applied Science Carinthia joint local team and buildCollective to build the extension of the primary grad1 and 2+++++to compare different construction methods on climate issues the same classroom in size was built – not in light-clay like the grade 1 unit but – earth filled walls+++++self produced pillars and trusses are filled with earth between hessian and weldmesh++++++
The new year started right with a small project at the wild coast in the eastern cape province. The donated container finally arrived and construction on the temporary workshop unit started.
Climate conditions differ much from Johannesburg but buildCollective approach stays the same.
As the hot and humid climate at the exposed site does not necessarily suit the light-clay and less insulation capacity but rather cooling qualities are needed we looked at some buildings in the area.
To stay green, easy and fast to build and provide protective cooling qualities we adopted the traditional construction of woven branches filled with earth. Three 200 by 70 Pillars were casted, hessian (jute) and welding mesh were tightened around them, connected with wire and filled up with earth. A new self-produced truss was created – timber with bended flatsteel , much lighter and easy to join and rejoin.
A small team of three people of the neighbourhood joint the experimental workshop construction and were excited by the strength of the wall. After filling the wall got an ordinary plaster job by the local team.

++++++most suitable clay in town++++++ different mixes in different colours+++++ traditional South African clay construction methods +++++mix proportions for different layers to plaster the straw-light-clay walls ++++++++++ red sand, clay, lime (whitewash), small straw and some cement.+++++++ Inside the classroom yellow sand and more lime to get a light colour++++++++++ left out the cement and chicken wire as lathwork at all and used red clay, sand, whitewash, straw and jute as plaster reinforcement to fully keep thermal and constructive advantages of the light-clay.++++++
+++++++++++japanese accurateness, good tools ++++++++++ starting with the corners to avoid cracks+++++++ layers with different mixes, patient drying process and straight edges to continuously floating and brushing at the end to get the famous shiny topping.
