All good things must come to an end

… and 2014 is no different.

2014 course collage

It is with pride and joy that we look back on the successes and new connections made during 2014.
We launched our blog in March and have had over 5000 visits from people in 98 countries! The blog contributions included knowledge shared by our expert natural builder Peter McIntosh, to fly-on-the-wall takes of life as an architect and educator interested in building naturally and sustainably by Hermie Delport, personal lessons learned by owner-builder Laurie Simpson, and Amanda de Gouveia’s contributions as social development researcher at Qala Phelang Tala, a grassroots community upliftment and alternative building project focused on vulnerable communities in Bloemfontein. Other contributors included heritage consultant Lesley Freedman who about using indigenous earthen architectural knowledge, and green architect Malcolm Worby shared his thoughts on a comparison between natural materials.
Peter wrote a special piece for The Green Times, South Africa’s Green News Portal, on the relationship between building naturally and building sustainably; and our most popular posts this year on the blog has been his three part series on Understanding Earth, how to test earth, and how to make the appropriate decision with regard to plaster and mortar mixes.

Peter McIntosh facilitated three courses this past year: two CPD accredited courses at Magic Mountains in Barrydale, and one 6 day Natural Building: Materials and techniques course at Khula Dhamma in the Eastern Cape. All-in-all 33 people attended these three courses and got to do the mud dance and experience the art of natural building. Hopefully, that translates to at least 33 more natural buildings in South Africa!
Khula Dhamma reckons the course is a winner:

‘It’s hard work but huge amounts of fun, highly therapeutic and more rewarding than one could ever imagine. With the different techniques and materials and their thousands of capabilities, you are literally only limited by your own imagination and there is something so beautiful about that!’.. Read more.

If you want to see what other participants had to say about the courses please visit our updated Testimonials page. Or if you’re interested to see photos of the courses, you can either go to our albums on Facebook, or visit the Gallery page on the blog. Thanks to everyone who has liked, commented on, and shared our posts and events on Facebook! Our page has continued to grow, and we now have over 1200 likes, all thanks to you. If you’ve attended one of our courses, please note that we’ve now added the option to review us on Facebook.

Finally, Peter McIntosh has been part of an amazing project at the Lebone Village Arts and Culture Centre in Bloemfontein as one of the Mentors4Change. This collaboration with Qala Phelang Tala (Start Living Green) started on Mandela day, July 18th when Peter trained a few hundred people in the art of making mud bricks. Amanada de Gouveia wrote about the day here. Since then they have had a team consisting of volunteers and outpatients from the  University of the Free State’s Occupational Therapy clinic in Rocklands location, hard at work on the Shack Replacement project. This team was also privileged to attend the course at Khula Dhamma.
In recent weeks though, the focus has shifted to the Lebone Arts and Cultural Centre and the existing above ground cistern at the local orphanage. The crew includes volunteers, outpatients from the occupational therapy centre, a crew from Guatamalan NPO Los Técnicos (arguably world experts in alternative building practices [tyres, bottles bricks etc.]), and Peter McIntosh . Here you can see the progress from day one to day nine (photos courtesy of Los Tecnicos). For more photos of the building progress, please visit their Facebook album of the project.

The project is set to continue for another week or so, and hopefully they’ll get it all done in time. A great partnership has been fostered between these three organisations and holds great promise for other projects in 2015… Watch this space!

Finally, thank you to old friends and new for a blessed 2014. We’re looking forward to continue this muddy journey in 2015 as we explore new relationships and exciting new projects, more photos, knowledge and experience in how to build naturally and sustainably, to bring you, our supporters. We’ll be publishing our course dates for 2015 early in January so do keep an eye out for that if you missed out this year.

Thanks for joining us again, and we’ll connect with you sometime, somewhere soon…

Warm regards,
the Natural Building Collective

The reflections and observations of a sustainable practitioner on the recent International Union of Architects World Congress (UIA) in Durban

As a senior lecturer in the Architectural Technology department at the Cape Peninsula University of Technology I get the opportunity to write and present papers at conferences, congresses and symposiums, with the benefit to see what is happening in the field and to consider where my own work is situated and where it could be going. Last week I was privileged to attend and present at the International Union of Architects World Congress in Durban. Besides the wonderful weather, I got to experience being part of an international discussion on practice and education, attended by about 4500 people from around the globe.

In the words of the conference organizers, the theme was ‘OTHERWHERE – looking elsewhere for other ways of creating a better future. The subthemes were ‘resilience, ecology and values’. ‘Resilience‘ explored questions around ideas of emergence, poverty alleviation, and the spatial economy. The second subtheme of ecology sought to “acknowledge the role of the architect in a bigger, interlinked, and systemic network and encourage a longer term view in the design of the built environment”. The third subtheme, ‘values‘, explored approached to “practice in Africa with a feeling that the agency of external donors needs to be tempered to benefit local inhabitats – who are currently being excluded from their own self-determination”. These themes resonated with my own experience as an educator and someone that is passionate about natural building.

The underlying tone of the Congress was self-reflexive, and a lot of presenters questioned the role of the profession while almost demanding it to become more responsive to both social and climatic issues facing the planet. There was a call to move from the “starchitect” syndrome to a more huminatarian and appropriate technological approach. This call resonated strongly with the paper I presented there with Rudolf Perold entitled “Towards Entrepreneur-Activist Architectural Practice”. We started with this quote:

“For we may soon find that we have too many architects skilled at designing museums and mansions and too few able to work with indigent people and communities in need of basic housing, sanitation, and security” (Fisher 2008). 

One of the key note presentations was by Toyo Ito, winner of the Pritzker Prize in 2013. The form of the buildings presented could have one swooning, but the underlying tectonic principles of that form took so much steel and concrete that one cringes at the environmental effect. The formal ideas of most of the buildings were apparently inspired by nature and natural principles, for example, the way in which a tree grows or the bones in a human body connect. But that is where the analogy to the natural ended for me. Such a form executed in steel and concrete, in my opinion feels entirely inappropriate and becomes an empty albeit beautiful response.

But then there were also keynote presentations by the likes of Cameron Sinclair who started Architecture for Humanity in 1999 together with Kate Stohr, with a cellphone and laptop and one or two projects. Currently the organisation is involved in designing, developing, managing and financing the construction of a variety of projects in over 20 countries (Aaronson & Architecture for Humanity, 2012). Their modus operandi is to embed architects on site that volunteer and help restore or rebuild community facilities, often in the aftermath of disaster. What wonderful work they have been doing over the past decade or so!

Another personal highlight was from keynote speaker Francis Kéré who you probably know of if you are reading this blog. Francis Kéré came from a small village in Burkina Faso, studied in Germany, then returned to his own country to work in his own community. He went on to win the Aga Khan award for Architecture with his very first building! He does work similar to that of Architecture for Humanity, but he works mostly in African countries, almost exclusively with natural materials and has a deep understanding of local passive design strategies. It is worth reading the “about” page on the website, and browsing the projects that they have done and are involved in.

There were many “side shows” at the congress. I presented in two of these with my colleague Rudolf Perold. The first, was the Architectural Education Forum (AEF), a locally initiated forum which “critically discuss how to improve architectural educational practice here and now and to exchange relevant information. Its main focus is issues that are relevant to architectural education in Africa, especially sub-Saharan Africa, which includes global and regional concerns. Its membership consists mainly of teaching staff from schools of architecture from over Africa, but there has also been support and interest from other associations concerned with architectural education based on other continents” (Janse van Rensburg, A. 2014).

The presentation that followed ours in the AEF was by Professor Vasanth K Bhat from Bengaluru, Karnataka, India, where he is Dean at Acharya’s School of Architecture and has his own practice. He presented “A Case for Inclusion of Appropriate Building Technology and Sustainable Building Design in Undergraduate Curriculum in Developing Countries” and discussed the inclusion of local earth technologies into the undergraduate curriculum. Often architecture programs follow a very generic curriculum without specific local content and he is making a concerted effort to include locally relevant technologies.

Our second presentation was for the Global Studio. This studio focuses on work in and for communities. Again there was much discussion that resonated with our paper about the architect becoming a more active participant in society. We discussed the idea of “architectural professionals that have re-defined the manner in which they work, and for whom they work, specifically addressing informality and poverty in their practice. These professionals are changing from being predominantly pre-determined problem solvers into a problem identifiers or project initiators” (Cary & Public Architecture, 2010, p.xii). This change in work approach asks of the architect to become an entrepreneur, identifying the project and problem and then finding the funding to pay for both the professional services and the execution of project. A place has opened, locally and internationally, for this new kind of professional – one that works on the ground, close to the needs of the broader community”. (Voulgarelis and Perold, 2014)

In my opinion, UIA 2014 was all-and-all successful and gives me hope for the future of (earth) architecture in the world.

Reflections and observations on a recent visit to the former Transkei

I had the pleasure of recently visiting a really magical place, Mdumbi in the former Transkei. Mdumbi is about 30km north of Coffee Bay in the typical rolling green landscape. Travelling with fellow architects Carl Morkel and Wim Els at a slowish pace, either walking or watching from the car window, one is aware of a soft silence, endless, gentle rolling hills with the silhouette of small pastel huts and sometimes the ocean in the background. Grandmothers moving peacefully and slowly, a shout from one hillside to the next, fishermen just appearing as almost out of nowhere.

Figure 1: Typical Transkei landscape, round huts in pastel colours.

One would like to think of this place as the ultimate sustainable example of natural building. Huts have been made here forever with soil and clay, either with using the wattle and daub or with mud brick method. You could easily imagine that all buildings here are still made with the smallest possible footprint on the earth. There are tiny mud brick making “factories” all along the roadsides, with clay being excavated directly out of the hillside and the small holes being covered with grass growing over it fairly quickly. People are going about making the bricks, talking, mixing, moulding, laying the bricks out to dry.

Deep-rooted traditions, foreign to outside observers, is visible in the very nature of the buildings, with huts in ruins not because of a lack of maintenance but out of respect for the inhabitant that has passed to another life, with contemporary car tyres forming the crown of the round roof and sharp pieces of glass embedded in them, not for adornment or ornament, but to keep the evil owl away.

The “evil” that has crept into this landscape dispels the romantic idea that all here is inherently sustainable. The landscape is pock marked with entire hill sides being bull dozed to mine sand and left un-rehabilitated. Thermally poor performing materials with a high environmental cost, such as concrete block have become the status symbol for affluence. Understanding of all the reasons behind these changes, which are many, is the topic for another discussion, but the low maintenance of a concrete block building cannot be left out of the picture.

The “charm” of the degradable, organic buildings is thwarted by the very aspect that makes them charming. If just left, they can degrade. Easily. The national “eradicate mud schools” agenda is by now well known. It is a multibillion-rand programme. This year alone the delivery delays on this programme have apparently cost 7 billion rand. (Legal Resources Centre, 2014) The mud school has developed a very bad name. And it is only through involvement and education that this will change.

Figure 4: Wattle and daub degrading

The reasons for the mud schools have a bad name is given one blogger as “having no toilets, having no electricity, having not water, coughing in a dusty classroom where the roof is caving in”…………..this from Also read this and this

Why do these school buildings perform so badly? Traditional Transkei buildings require constant maintenance, since most of them lack the two really important protection criteria that natural buildings need to survive. A proper hat and boots. In trying to convince role players that it is not necessarily the “mud” that is the problem in these schools, Lesley Freedman and Andy Horn recently met and then sent a letter to Equal Education to introduce ideas around proper “mud” building standards that will not only improve the schools but also houses in the surrounding villages.

This brings me back to our reason for visiting the Transkei. We went there to take part in discussions regarding the development of a wonderful initiative, Mdumbi Green Destinations. This is a project envisioned by Mdumbi Backpackers in association with the Mankosi community. The Mankosi community will develop a community owned tourist facility where, amongst other sustainable aspects, the buildings will be made with natural, local materials. The local community will be integrated in the design, development and building process and will, apart from getting ownership and employment during and after the process, they will learn about using their local materials in an effective way that makes it last longer (and of course food production and other environmental sustainable things, but we are concentrating on this blog on natural building).

Spin offs of the initiative is that the Mdumbi Backpacker community has learned some valuable lessons and skills about natural building in the long process (read years) towards the project becoming a reality. And some of them learned these skills at Berg-en-Dal.

Through the Transcape “arm” of Mdumbi backpackers that focuses directly on assisting the community, an Eco Centre has been opened. Already here mud brick making, proper building methods (and food gardening) is taught to the local community. What is interesting that we observed when visiting the Eco Centre is that it was predominantly young men and women that took part in the mud brick making workshops, where at the “factories” next to the road it was mostly older women working.
