A brief look ahead at our natural building courses for 2018

Attend our natural building course and take the first step to a sustainable future by learning hands-on natural building skills. Learn a whole range of materials and techniques while exploring questions around sustainable living based in Peter McIntosh’s experience living off-grid since 1999.

Natural building courses in South Africa 2018

If you’re serious about building naturally and sustainably then you’ll know that each technique has pros and cons. That is why our natural building course is designed around the principles of understanding earth, how it works and does not work together. You will leave with the theoretical understanding and practical grounding of a range of techniques and materials, so that you are able to make the most appropriate decisions regarding materials and or sustainability once you are ready to begin your project.

This year, Peter will be hosting two CPD accredited courses at Jakkalskloof farm, in Swellendam. Continue reading

Guest post: Hybrid alternative and natural building blocks at the Delft ECD (Early Childhood Development Centre)

In Delft, an impoverished township on the outskirts of the Cape Flats, local government is changing its approach to building early childhood development centres with a pioneering project showcasing a hybrid of natural building methods and up-cycled waste materials.

Peter McIntosh, founder of the Natural Building Collective was the project coordinator for the alternative materials (natural and recycled) portion of the Delft ECD build.

The new Delft ECD (Early Childhood Development Centre) represents the first time that government – in this case the City of Cape Town – has significantly integrated alternative and unconventional building methods for the construction of a public building.

The considered design of the Delft ECD building is an example that will make an essential contribution to the development of South Africa’s youngest residents. The alternative building materials, which include both natural methods (compressed earth bricks and cob) and recycled waste materials (ecobricks, tyres, glass bottles), deviate from conventional brick and concrete, while creating a healthy environment.  Continue reading

Q&A with Paul Marais, award-winning architect specializing in rammed earth

We catch up with Paul Marais about his award-winning off grid, rammed earth house in Maun, Botswana.

First off, congratulations on winning the Afrisam-SAIA Award for Sustainable Architecture + Innovation for Sustainable Product/Technology for your design of the rammed earth Otto cottage in Maun, Botswana. 

Thank you, I am very pleased for recognition of this off grid, rammed earth building , where I designed and built the house, energy & water systems and sewerage.

How did you first get involved in natural building?

I have been always interested in natural buildings and as a student studied natural building in Malawi and Zambia.  I have travelled a lot in remote Africa and have an interest in indigenous architecture which is both material and energy efficient.  Continue reading

Guest post: Rammed earth on the rise

Rammed earth construction in South Africa has generally been stigmatised as a substandard and primitive building construction method reserved ‘for the poor’. Yet it is now gaining popularity for community social projects, as well as among wealthier clients.

Rammed earth in Botswana

House Freeman is cool in the hot Botswana desert thanks to an evaporative cooling system, which draws air over solar powered sprinklers, a living roof and thick, thermally efficient walls. The shuttering was reused in, for example, the roof, so nothing was wasted.

Of more than twenty different types of earth construction techniques, rammed earth has been lauded for its durability, sophisticated environmental performance and striking earthen beauty.

Rammed earth construction in South Africa has generally been stigmatised as a substandard and primitive building construction method reserved ‘for the poor’. Yet it is now gaining popularity for community social projects, as well as among wealthier clients. Although a building standard is yet to be formalised in South Africa, the rammed earth industry is established in many African countries, Europe, United States and Australia. This means plenty of expertise and established international building standards already exist and this construction method is now far removed from its primitive roots.

From the ground up ~ approaches to building a foundation for your natural building

When building with earth your foundation needs to be well considered as the integrity of your building rests here. Decisions you make about your foundation depend on the materials you have available, the type of ground you have to build on and what carbon footprint you want to leave. The goal should be to create foundations that are hard enough, move uniformly and resist cracking for the walls above it.

Foundations for conventional building have, to a large extent, a one size fits all approach regardless of the type of ground you are building on i.e. a concrete and steel foundation that works equally well on all types of earth and varies only slightly in its design. It requires little thought and has been proven to be effective. The cement in concrete provides the compressive strength, and the steel tensile strength to resist cracking. It does however come at a cost to both your pocket and the environment.

When building with earth your foundation needs to be well considered as the integrity of your building rests here. Decisions you make about your foundation depend on the materials you have available, the type of ground you have to build on and what carbon footprint you want to leave. The goal should be to create foundations that are hard enough, move uniformly and resist cracking for the walls above it. Foundations will always have a higher Mpa value than the walls, however it does not need to be excessive. A 4 Mpa foundation is sufficient for a 1.6 Mpa mud-brick wall, which most types of foundations are suitable for. Furthermore, if after levelling the site the undisturbed earth is hard enough, foundations may well be unnecessary.

There are several strategies for foundations depending on the type of ground that you are building on. In this blog post, I discuss the four types of ground, (1) uniformly hard, (2) uniformly soft, (3) hard and soft, and (4) clay, their challenges and several strategies you may incorporate into your design. The discussion is quite technical in some areas so I recommend that you read my three-part series on understanding earth first. Continue reading

The dynamic qualities of African Vernacular Architecture

In this guest post by Jon Sojkowski, he chronicles common misperceptions of African vernacular architecture and how it is being abandoned for the status that comes with living in conventional Western style buildings. He asks whether these modern materials are truly better than the vernacular options.

By Jon Sojkowski

African vernacular architecture is a subject that has had very little attention. The lack of documentation and available data on the internet has led to a severe misunderstanding of a type of architecture that a large percentage of the population in Africa living in on a daily basis. The lack of data has led to negative perceptions regarding African vernacular architecture, mainly that it is temporary, primitive or for the poor. Most people, when they think of a mud hut, get an image of a dilapidated mud structure which is quite small and has a thatch roof. Sadly, this perception exists both inside and outside the African continent, but it is simply not the truth. Continue reading

Breaking news: Six day course at Khula Dhamma, near East London 25 – 31 October 2014

I have been contracted to facilitate a six day course at Khula Dhamma, near East London at the end of October. This is in addition to the accredited course that I’m hosting at Magic Mountains retreat, near Barrydale in the Western Cape at the start of October. Both courses will cover the same basic topics, but you will be working with somewhat different materials. So if you can’t join us for one, maybe you can join us for the other course… Cobworkshop-KDRC
