We’re thrilled to announce Peter McIntosh will be co-facilitating Long Way Home’s inaugural Green Building Academy in Guatemala this year. Participants can expect a solid grounding and hands-on experience in green, sustainable building and construction practices, social development and a rich cultural immersion. The Academy will take place in Comalapa, Guatemala, and will draw on the expertise of the Academy‘s instructors, who for 9 years have built an 18-building school using state-of-the-art green and sustainable technologies and methods.
The Green Building Academy provides a menu of unique educational options that are relevant to both professionals and students inside AND outside of the construction industry. Guided by best practices in green construction, the Academy is dedicated to educating individuals and organizations, in both theory and practical application, about sustainable design, planning, and building practices. Participants will connect to their environment, and develop increased consciousness & competence relating to sustainability, environmental & ecological balance, and ethical & respectful community development. The Academy equips participants with the knowledge, skills, and dispositions to apply their creativity to design and construction using sustainable, unconventional materials and low-impact methodologies with potential for off-grid implementation.

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.
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
In honour of women’s day we asked Anita Venter a few questions about her grassroots development initiative using sustainable building methods in Bloemfontein. We have great admiration for the shack replacement initiative and what she has done to empower her change agents to become more self-sufficient and build community in her local context. We first got to know of the work Anita does when she invited Peter to participate in the Lebone Arts and cultural centre, a collaborative project with Los Tecnicos in 2014. We were also honoured to host her and six of her change agents on one of our natural building courses in 2015.
How did you first get involved in natural/sustainable building? Tell us about the journey.
Since the early 2000s I have done many research studies on housing from socio-economic and policy perspectives. Continue reading
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.

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
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.

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.
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

Passive solar design can dramatically reduce our demands on fossil fuels and other forms of energy input, allowing our buildings to become producers and not consumers of energy and resources, supporting us in a healthier more comfortable abundant way.
Passive solar design is the starting point of sustainable building. Once one understands the basic principles of using the abundant natural renewable resources at our disposal we become more creative in our approach to design, more in tune and observant, reconnecting us with the natural rhythms that surround and sustain us, if only we would pay attention. Sustainable buildings save money, reduce your carbon footprint and provide a healthy living environment, transforming buildings from consumers of energy to producers and forging buildings that meet our needs.
From a permaculture perspective, incorporating these aspects into the design of your home are excellent examples of several permaculture design principles. To mention the most obvious: Observing and interacting with your environment to make the most of the sun’s migration, catching and storing energy, using and valuing renewable resources and services, integrating functions and elements rather than segregating them and obtaining a yield from the planet’s most abundant energy source, the sun.
Passive Solar Design uses the energy provided by the sun and stored in the earth. First we need to look at how this energy is utilized by defining insulation and thermal mass and then look at the strategies of how to incorporate them into our designs.
