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 →
“The future belongs to the few of us still willing to get our hands dirty.” – Roland Tiangco
As the end of the year approaches, we want to wish you well over the festive season, and thank you for your support in 2017. You helped us finish the Delft Early Childhood Development centre, start and almost complete a training centre for early childhood development in Delft, as well as host our two usual natural building courses and co-host a sustainable building course with earth and tyres in partnership with our friends Long Way Home. Prior to the course Long Way Home commissioned a manual for sustainable building which was authored by Peter McIntosh and Guy Williams (LWH).
During the past year, we were part of the design team for a new ECD in Strand with our focus on sustainable materials and passive solar design. It will be built from rammed earth, compressed earth brick and some ecobricks, offgrid and treat its own black water. This five star rated green building will serve a disadvantaged area in Strand for around 400 children. Unfortunately, it’s on hold due to the current drought. We have also been giving design inputs on other City of Cape Town projects that are in various stages of planning. We are also working with Ikamva Labantu on using sustainable building in ECDCs in the NGO sector.
It has been a tough year, but a year of advances too. So we would like to give you an overview of the year, and to thank you, especially our donors, friends and volunteers, for the contributions you have made to the successes of the year.
We give you a very brief recap of the blog and then continue to update you on the Delft ECD, as well as our progress with the training centre. 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.

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 →
In the first of our series of Q&As with pioneers of natural and sustainable building in South Africa and beyond, we caught up with Jill Hogan in honour of Women’s day in South Africa.
How did you first get involved in natural building?
Jill Hogan at Cobbit’s Cottage.
In the early 90’s my life changed completely and I found my self alone. In wanting to be part of a community, I met Hurta Stuurman and did some work with her on her cob house at Hermanus/Stanford and knew that this is what I wanted to do. It combined my concept of Permaculture with creating an organic home for myself, while allowing me to use my knowledge of earth/clay.
Tell us about your journey.
In the 70’s I worked for a nursery. I had a pot plant business, but was exposed to organic veggie gardening and became more and more interested. At the same time, I started doing pottery and assisted in teach children with learning disabilities now known as ADHD, and so was exposed to lateral thinking.
In the 80’s I went back to “school” and did a fine arts majoring in ceramics.
In 1992 I was introduced to Permaculture and did the design course with John Wilson from Fambidanzia, at Tlholego in Rustenberg, and I developed a true passion for sustainable development.
Someone was setting up an Eco Village in McGregor and I was drawn to become one of the original developers. But personality clashes among the original six members caused the project to collapse, sending me into McGregor itself where I bought a piece of land in the town. 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.

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.
Do we as ethical natural builders have a right to deny someone a home simply based on the argument of its purity? Surely it’s about having the humility to acknowledge that sustainability is about economy and social justice as much as it is about ecology. Scott Gallant from Rancho Mastatal in Costa Rica writes that the transition ethic says that no one is going from zero to sustainable overnight. Making the transition takes time and, we have to meet people where they are at.

To introduce the post, we’d like to share with you why we were so excited to read Scott’s post. Written by Scott Gallant from Rancho Mastatal Sustainability Education Center in Costa Rica, the post is based on his experience teaching the three permaculture ethics during the center’s Permaculture Design Courses, and the realization that a fourth ethic is required in order to facilitate a conversation about compromise. They filled the gap with the Transition Ethic. Scott quotes Jessi Bloom and Dave Boehnlein, authors of Practical Permaculture, who acknowledge that “the transition ethic says that no one is going from zero to sustainable overnight. Making the transition takes time.” He goes on to say that “We have to meet people where they are at.We must understand their cultural context.” Continue reading →
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 →
