Owner-builder journey: living the simple life living alongside wildlife

Laurie first wrote for us back in 2014 about her journey as an owner-builder and the challenges of building with mud on the edge of Hwange National park, Zimbabwe. She recently posted an update and we knew our readers would want to see what she’s been up to… Their family home is complete and their gardens are thriving as they continue to live a simple life alongside wildlife. 
It’s been a while since I’ve had the time to post anything and people have been asking how the house is, our life here, and so here is a photographic update.
The house is a dream come true, to wake up every day in these hand moulded walls feels sublime. The metal termite barrier works and checks are regularly done around the stone stem wall to check for tunnels to knock down.

Q&A with Jill Hogan, a pioneer of natural building in South Africa

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


Transition Ethics: The Art of Compromise

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.

This post first appeared on Numundo on 16 February 2016. We are re-posting it here with the permission of  Shayna Gladstone and author Scott Gallant.

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


How to incorporate passive solar design in your building, using thermal mass and insulation.

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.

DSC01797_edit 1

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.

Introduction to Cob building – Kenya

The Permaculture Research Institute in Kenya will be hosting a seven day cob building course. The course aims to be a part of the revival of natural building in Kenya; to help revitalize an ancient art and incorporate new techniques learned through past decades as natural building has gained traction internationally. 

Earthen Shelter in collaboration with the Permaculture Research Institute (PRI) in Kenya

WHAT: A hands-on course appropriate for both first-time builders and for professionals in the building trade who are interested in natural materials. In this seven day cob workshop, the focus will be on the characteristics of the natural materials most commonly used in construction:  clay soil, sand, and fibers.

WHO CAN PARTICIPATE: The course is appropriate for both first-time builders and for professionals in the building trade who are interested in natural materials.

WHERE: Laikipia Permaculture Centre is a 1.6 hectare farm located on the Laikipia Plain, north of the Rift Valley in Central Kenya. Founded in 2012 by permaculture teacher Joseph Lentunyoi and Permaculture Research Institute Kenya, the project aims to illustrate how regenerative agricultural practices can improve local food security and community health while preserving and rehabilitating precious ecological resources impacted by overgrazing and other unsustainable use patterns. As a demonstration site for water harvesting and conservation strategies, soil fertility building, holistic pastoral management, natural building and many other sustainable practices, LPC is developing a model with far-reaching potential for Laikipia, Kenya and East Africa as a whole.

WHEN: January 18- 24, 2015

PROGRAMME HIGHLIGHTS: The course aims to be a part of the revival of natural building in Kenya; to help revitalize an ancient art and incorporate new techniques learned through past decades as natural building has gained traction internationally. Benefits to participants and the local community will include acquisition of the skills necessary to build climate-controlled, sustainable, non-toxic, affordable housing without acquiring substantial debt.  The artisanal and ancestral skills of natural building have largely been lost through the 20th century. Commercial materials and conventional building styles have benefited from industry biased-regulations and are now largely associated with status and prestige. This is the case in Kenya, a country that is integral to the history of natural building and that still contains communities reliant on natural housing.

In this seven day cob workshop, we focus on the characteristics of the natural materials most commonly used in construction:  clay soil, sand, and fibers.

(1) The main focus will be cob, which combines these readily-available materials to hand-sculpt beautiful walls, benches, ovens, and fireplaces.

(2) Various other building techniques that utilize the same materials, including adobe block, light straw-clay, wattle and daub, and plasters will also be touched on.

(3) Discussions will be held on how to find and choose appropriate soil for construction, how to create various mixes and plasters, how to incorporate timber and stone, and how to use earthen materials to build walls, sculpt niches, shelves, and furniture.

(4) As a complement to the hands-on portion of the course, slide shows and discussions of the science and theory of natural building will bring deeper understandings and answer any questions.  Subjects include building design and siting, passive solar design, foundations and drainage, earthen floors, appropriate roof design, and wiring and plumbing for natural structures.

APPLICATION: To apply, please register online with the PRI .

Owner-builder journey ~ Building ‘home’

In the first edition of the Owner-builder journey, Laurie Simpson writes about the challenges of building with mud in on the edge of Hwange National park, Zimbabwe.

Seven years ago, after years of travelling, looking for the next adventure and never feeling like I belonged, I followed my partner to live in his home, Zimbabwe. The moment I arrived I knew I had arrived ‘home’, even though I had never set foot there before. It was a strange and beautiful feeling and one that kept me from leaving despite many difficult times over the years.

Two years ago, I started building ‘home’ using mostly materials that are found around us. It’s been an amazing journey of self-discovery. It started with reading books and articles that inspired me to live a life that was in sync with nature. Previously, I felt like we were just spectators watching nature go by as if we were not a part of it. From all this research I quickly realised just how destructive modern building techniques were and how much sense it made to build with natural materials.


I decided I needed some hands-on experience before I could start building ‘home’ for our family. I discovered Berg-en-Dal eco-village and enrolled myself on the natural building course. The course was both practical and theoretical and I had an amazing time with the two facilitators Peter McIntosh and Neil Smith. Other than this short one week course I had no building experience at all, but I felt it really gave me the confidence I needed to throw myself into my own project.

I went home and started to test soils and plan my building project. I wanted to build this home totally by myself as it felt so personal and I loved the process. I also saw how in the community around me some women were still building traditional huts using natural materials. The huts are made from very high clay soil, usually from a termite mound and so crack a lot. Since restrictions were set for where people could live (there are no fences, so wild animals move freely) homesteads are no longer temporary, and the longevity of these buildings began to matter. These days, people opt for more modern materials that are costly both financially and environmentally. I wanted to prove to myself and to others that it was possible to build a home from natural materials that was comfortable in our climate, could last a long time and meet all our needs.

From the beginning, I fell in love with the process of cob building, mixing sand, clay and straw with my feet and making big balls of this mix to sculpt the walls. I was so in love with cob in fact that I was blinded.  I had made up my mind even before trying cob building on the course; and once I started ‘mud dancing’ that just sealed the deal for me. I was also set on doing everything 100 % natural and making no concessions, that I ended up making some mistakes.  I started to see this after a year of building a somewhat large round cob house. I had built the stone foundations and half of the cob wall, but as I was building alone it was very slow and the rainy season was approaching. I had to cover the walls to protect the cob as there was no roof yet.


One of my biggest fears when I was first researching cob building was termites. There are many termites where we live and they go everywhere. Still, I didn’t want to put a metal termite barrier between the foundation and the walls as this was both an added financial and environmental cost. Yet, when I covered the walls the dark moist environment was perfect for them, and they moved in to the walls. It was very difficult to face, but I had to reconsider everything!

I had started to be interested in natural building because of Permaculture, a process of designing systems that work with nature rather than against nature. I realised I should have done a Permaculture Design Course (PDC) before doing a natural building course, as this would have given me the tools I needed to think through all the elements and design a home with nature in mind.

So back to Berg-en-dal I went to do a PDC. I had to re-think and re-build my confidence to continue, and after two amazing weeks, a lot of emotion and good advice from Peter McIntosh and the PDC facilitators, I had the energy to go back home and rethink and re-design. It has been just over a year now, and I am almost finished building what has changed into a small home. It has just two small bedrooms and a small living space, the rest are verandahs and outdoor spaces. I will still use the previous structure, but in a different way.

I learnt my lesson and adapted: I could still do mud dancing but now made sun-dried bricks. I made many new tests using the same clay that my neighbours were using. The difference being that I added sand to stop the bricks cracking and made very thick walls. I made sure I had finished these in the dry season and put the roof up on poles before the rains started. I had one person helping me some of the time and I called for help whenever I needed more specialised information. The foundations are stone again and this time I made a metal termite barrier between this and the walls.

To see our dream come to life is amazing. It’s been an exciting journey thus far and it’s only just begun, in the next couple of months I hope to move ‘home’ with my family and carry on testing and promoting natural building and Permaculture in our community. There are many challenges living with wild animals such as elephants and lions and surviving from the land. The soils are very sandy and the dry season can stretch out for very long periods, but I believe that there are simple and practical solutions so that we can take care of both people and wildlife.
