We’ve launched a crowdfunding campaign because we really need your help to finish building the edu-centre in Delft so carers from informal crèches can get training in early childhood development.
We are busy building a passive solar, earth sheltered building out of tyres, cob, compressed earth bricks and glass bottles at the Delft Early Childhood Development (ECD) centre. But, we need your help to finish building it. The building will be an edu-centre so carers from informal crèches can get training in early childhood development.
Following our involvement with building the Delft Early Childhood Development centre with natural and sustainable building materials we saw the space and need for an adult training centre there so that, amongst other things, carers from informal crèches in Delft and surrounding areas can receive training in early childhood development. It has been widely accepted that the first 1000 days in a child’s life is critical to their, as well as society-at-large’s health and wellbeing. During this period, children’s brains can form 1,000 neural connections every second and these connections are the building blocks of their future. But, we need your help to complete the building…
What we have achieved to so far:
Peter McIntosh has raised R120 000 from the Sophia foundation towards materials and has donated three months of his time towards the success of the project.
We have provided employment for eight members of the local community during the building process.
We have provided a month-long training sustainable building course including for architecture students of CPUT. The course was presented in collaboration with Guy Williams on behalf of international NGO Long Way Home from Guatemala.
We have also used provided other learning opportunities for volunteers, architecture interns.
We need to get from here:
How we’ll use your contribution:
With your help we can complete this building… Your contribution will go towards completing the following activities:
Planning gum pole purloins to level to install roof sheets
Installing IBR roof sheets
Complete last two sections of ring beam (shutter/form and pour concrete)
Source and make over 2000 more bottle bricks
Install bottle bricks in cob above ring beam
Cob scratch plaster coat, form coat and final lime plaster coat internally
Form and final plaster coat on internal and external bottle walls
Level and stamp floor
Gravel, newspaper, cob and compressed earth brick floor layers
Final layer on floor
External plaster finishes on tyre walls and ringbeams
Final touches on tyre retaining wall and earth berm
Front level ramp and paving threshold
Painting fibre board on door-front
With your support we are making a difference… Thank you!
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 →
We are happy to announce the completion of another successful course at Wild Spirit Backpacker’s Lodge in April, 2016. The second CPD accredited natural building course will be held at Jakkalskloof farm, in Swellendam. Jakkalskloof is an organic mixed-use farm which also provides training in Biodynamic agriculture.
For more information about these CPD accredited natural building courses simply drop us an email at: firstname.lastname@example.org

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 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.
As we’re heading into winter South Africa’s continued loadshedding will have an even greater affect at home and work as people spend more time indoors requiring amongst other things more lighting as well as heating. We are blessed with abundant sunny days making solar very reliable without the need for a lot of backup storage in the form of batteries. If you are considering going off the grid, whether partially or fully, my previous post will give you a basic understanding of how solar energy works and the components of the system. In this post, I show you how to calculate your energy requirements, as well as choose an inverter, batteries and solar panels to suit your needs.
