Date/Time
Date(s) - Sunday, May 24, 2026 - Sunday, June 21, 2026
8:30 am - 5:30 pm

OUR HOST

Bom Dia! My name is Nuno Figueira and I was born in the southern Portuguese town of Faro and have lived in Lisbon for the last 20 years. My background has always been in theater and technical and visual experimentation using images and video-mapping in the visual and performing arts, helping transform mine and others’ visions and perceptions towards a new way of seeing. Parallel to this profession, I have been developing a new path in natural building or, in Portuguese, “bioconstrução”, which has also been integrated into my theater-based work.

Sitio Valverde is 6000 m2 of very special sanctuary land, located one hour northeast of Lisbon near the town of Coruche.  There we hold a variety of workshops and promote connection with Nature.  Situated in a quiet rural zone surrounded by green, it is an ideal environment to relax and disconnect from urban life.  We offer diverse activities including natural building, walks, yoga and meditation.  We offer accommodations in a typical “ribatejana” house as well as space for camping and caravans.

Sitio do Valverde is more than a space.  We also want to create a farm school for personal, social and ecological growth and development with practical and theoretical classes, like natural building techniques with Earth, bamboo and straw, as well as regenerative design.  We attract communities who value collaborative learning and integration with Nature and want to enrich their lives and those of their neighbors with new sustainable building systems and a greater respect for the Earth and Life.

 

THE LOCATION

Just a 20-minute walk from Sitio Valverde, the Sorraia River is the natural heart of the town offering birdwatching, aquatic activities, picnics, walks, and relaxation.  Nature is everywhere in the Coruche region and the landscape vistas are endless.  Here far from Lisbon, people come for the fresh air, the peace and the serenity.  One can also appreciate the land from above by taking a hot-air balloon ride and then on the weekends visiting the mountains, parks and “barragens” in the surrounding areas.  Of course the Lisbon area usually has many cultural and music events happening every weekend as well.

 

THE PROJECT

We will build an outdoor kitchen for Sitio Valverde with a cob oven and a rocket stove cooktop as well as benches, countertop, shelving and a space for a sink, all under a green reciprocal roof, built in Week 1.  This outdoor kitchen will serve as a gathering place for community celebration as well as a learning venue for ancestral and traditional hand-made crafts and cooking like bread-making and other healthful and sustaining practices.  The outdoor kitchen will strengthen community connections by offering a space for sharing experiences, exchanging knowledge and celebrating the simplicity and wisdom of the old ways.  Its construction reflects our commitment to sustainability, tradition and collaboration, fundamental elements in the creation of a living lively community in harmony with its environment.

 

DETAILED COURSE DESCRIPTION

 

Throughout the workshop, we will build a complete outdoor kitchen using Cob. The kitchen will feature a wood-fired cob oven, a rocket-Lorena stove for pot cooking, and various amenities such as shelves, niches, cob benches, and cob walls. The entire structure will be sheltered by a stunning reciprocal roof, topped with a green roof system.

In the first week, we will focus on constructing the roof, starting with the primary reciprocal structure, followed by secondary beams. We will then install the sheathing and a multiple-layered green roof.

During the second and third weeks, we will begin working with cob to build the perimeter walls (half-height) while simultaneously constructing the Lorena stove and cob oven. This parallel workflow will allow for proper drying times. Additionally, participants will receive both theoretical and practical instruction to ensure a thorough understanding of the techniques and materials used.

In the fourth week, we will add the finishing touches: sculpting and plastering the entire structure with a variety of earthen plasters.

This workshop covers a range of fascinating topics and skills and is the perfect opportunity for anyone eager to learn about natural building and specialize in earth-based cooking appliances!

 

GENERAL SCHEDULE

The 28-day Outdoor Cob Kitchen Workshop consists of 20 days (Monday through Friday) of learning & construction for 4 hours in the morning and 3 hours in the afternoon with theoretical instruction (lectures with graphics) on most afternoons to complement the hands-on experience.

Students arrive on Sunday between noon and 2pm and settle in. The Workshop begins at 4pm and ends on a Sunday, 4 weeks later, around 2pm. Students can arrive a day or two before to acclimate and settle in (please let us know) but will need to cover their own food
 needs and accommodations if not camping, unless a work trade or meal fee is approved by Host (to be decided closer to the date). The Opening Circle begins promptly at 4pm, followed by a Host Site Orientation at 5pm, Dinner at 6pm and an Introduction to the Project by the Instructors at 7pm. 

We require that students arrive Saturday before dark or Sunday by 2pm AT THE LATEST!!! We need to begin ALL TOGETHER, as the most important information for the success and smooth-running of the workshop and the well-being of the students will happen on Sunday between 4pm and 8:30pm.  It is very inconvenient for students, Host, Instructors and the group, when someone arrives late and misses any of the opening sessions.  Please be punctual because Monday morning at 9 am we begin prepping our roof rafters and getting them on the supporting structure!

Following Breakfast from 7:30-8:15am, the morning learning/building session begins at 8:30 am and lasts until 1pm with a 20-minute snack pause at 11am. Lunch break is from 1pm to 2:30pm, which includes a rest time before the 3-hour afternoon session begins, from 2:30pm-5:30pm. Mondays, Wednesdays and Fridays there may be a 60-minute lecture at 2:30pm, followed by construction time. Tuesdays and Thursdays students begin building again right after the rest time. After class in the afternoon there is a 90-minute break before dinner (served from 7pm to 8pm), in which students are encouraged to stretch, do some type of relaxation/movement practice, go swimming, walking and just relax.

There is sometimes a work trade student officially or informally leading yoga and movement practice in the mornings or afternoons (depending on student preference). There will also be 2-3 evenings (once a week) after dinner for showing slides, videos and having Course-related discussions. Other evenings are mostly free and sometimes students offer informal courses in their specialties and passions. Tuesdays are reserved for a weekly Council Circle, where we do a deeper sharing and listening to attend to the inner worlds of our students, staff & Host(s) during this intense workshop experience.

On weekends students are free to explore the area, rest onsite, and even continue building, subject to Instructor approval.  All weekend meals are provided by students who are welcome to use the kitchen.  Host and/or other students can carpool into town for weekend food provisions.

The 28-day Course will offer comprehensive practical learning by building a complete 14m2 curvilinear outdoor kitchen with roof, as 
described in the “Project” section. Those who complete this 28-day Workshop will receive a CruzinCobGlobal Certificate of Completion for an Outdoor Cob Kitchen including green reciprocal roof, cob walls, cob oven, rocket stove cooktop, sculpting and plaster.

**IMPORTANT NOTICE**!!!

 

These workshops are designed for people that want to learn how to build a complete structure from start to finish in a professional manner and amount of time. They are very intensive and, while we make time for yoga, stretching, dancing, music, relaxing….all students are expected to be present and participating in all building and lecture learning hours unless absolutely incapable due to illness or have some other significant/emergency reason. This is because we design the size of the build
 and organize the structure of the workshop in accordance with the number of students and when people are absent, it impacts the whole group and the other students have to work harder and it disturbs the integrity of the group. It takes the whole village to see a build from start to finish!  In addition, Instructors set up building work according to students’ strengths and learning needs.  In short, if you don’t feel that you will be able to be present every day for every session, please re-think your readiness for this workshop.  We attract serious and highly-motivated students so if that’s you, you will be surrounded by others with the same desire to learn and build!

For students wanting a more mellow slow-paced cob experience, along with time for personal exploration and experimentation following their own rhythm, these workshops are not for you! However, you can find a more suitable workshop online with other organizations that offer a
 shorter period, building a garden wall, a bench, a compost toilet or some other smaller scale project.

Students are required to read “The Hand-Sculpted House” and “Essential Cob Construction” (see website Resources page) before the workshop begins, as well as the cob oven and rocket heater/stove books they find or are listed on our Resources page, as well as books on plastering and reciprocal roof building.  We ask that you watch the many videos on our our “International Cob Workshop” playlist on Claudine’s YouTube channel, the new educational YouTube series “Building a Mud Home” by Cooper Green, posted by Natural Buildings and created from our North Carolina workshop footage, and the ones posted on CruzinCobGlobal’s website under Gallery, to get an idea of what is expected. Also it is a great idea to watch as many other videos on cob and reciprocal roofs as you can to come mentally prepared. Please bring your book(s).

Students must tend to their own personal needs, drink alot of water, rest when needed and work at a steady pace.  Please bring a watch or use your phone to be prompt and ready for each part of the Course including meals. Please make sure you share your dietary restrictions/allergies with CCG in your registration form. Note that very demanding dietary needs will not be
 able to be met (vegan & non-gluten ok) and those students may be recommended not to participate, unless they are willing to meet their special needs on their own, which will not include kitchen access on weekdays. Please discuss with Claudine at time of desire to register. Also please bring your essential snacks and foods, pillow and whatever you NEED to be comfortable and happy. Feel free to also bring playlists, speaker, slides, videos,
movies and books to share, as well as a sample of your soil to test.

We look forward to opening you to a whole new world of experience, skill, growth and transformation as you bond with your new COB family for life!

 

MEALS & ACCOMMODATIONS

 

We will serve three meals a day from Monday through Friday including the Welcome and Celebration Dinners and Farewell Brunch.  Weekends students will be on their own for food and may use the onsite kitchen.  Meals will be  vegetarian and locally-based as much as possible, including farm produce and eggs! Carnivores & pescatarians & omnivores will, if desired, be offered non-vegetarian options of meals a few times a week and/or supplemented reasonably with canned fish, dried meats, cold cuts. They are also welcome to buy additions to cook on the side.

We will attend to vegan and gluten-free diets if needed, but any other restrictions & allergies that require extensive preparation needs will probably not be able to be honored. And kitchen will only be accessible on weekends for students.

Camping with your own tent and bedding is free and our host Nuno will rent out beds in the house for 140€ for the 4 weeks from Sunday to Sunday. People who arrive early and/or or leave after Sunday please pay the adjusted amount with the nightly rate of 5€.

 

TRANSPORTATION

Students will get to Coruche from Lisbon by bus or carpooling with each other or using BlaBlaCar, a popular European carpooling service.  More information to come on getting to the workshop site…

 

CHRISTIAN EDER

Cob Instructor

Hello I am Christian and I grew up in Südtirol, a German-speaking area in the Alps in Northern Italy, surrounded by mountains and beautiful woods and lakes. From a young age nature and sustainability were part of my values, and that is why this particular style of building makes a lot of sense to me.

After finishing high school with a focus on economics, I worked in a trading company for some time, which didn’t satisfy me much. So I decided to do a computer science training, after which I worked as a web developer, but then decided to go traveling around the world for some years, and worked as a shepherd, industrial climber, fruit picker and waiter.  I traveled following my passions like climbing, hiking, nature, and Eastern philosophy, specifically meditation and yoga in India.  I love to get to know people from around the world, their cultures and their food. In essence I love the diversity of our planet and getting to know it first hand.  On the way, I have learned many languages: German and Italian at home, then English, Spanish, and some French during my studies and life, and am currently learning Portuguese.

After settling in Italy again, I worked as a landscape gardener, where I was able to gain experience that helped spark my interest in the Cob building path.  When I saw my first Cob Building in California a few years ago, Natural Building got my attention and Cob, especially, felt like the path I wanted to dedicate myself to. While I first studied independently with books to gain basic knowledge, I then felt a strong desire to delve deeper into this new/old field. That’s when I decided to sign up for my first Complete Cob Building Workshop taught by CruzinCobGlobal  on the beautiful island of São Miguel in the Azores.

I immediately felt drawn to building naturally with no huge impact on Nature.  I am fascinated with building, not only the construction side itself, but the community aspect as well. To create something with like-minded people feels right and is fulfilling and fun.  I also attended a bench and oven workshop at the same site, and went on to build a cob compost toilet as a return student at Quinta da Vida Beleza, Claudine’s Ecovillage Farm in the Azores.

Since then I have been building and teaching many projects. In winter of 2024, I collaborated with my colleague Zoe, who also trained in the Azores CCG Advanced Certification Workshop in 2023, and we taught local volunteers while building a stunning outdoor classroom in Zanzibar for an educational non-profit.  

In the summer of 2024, I attended a CCG Outdoor Kitchen Workshop taught by Master Cobber Viva Hansen, who specializes in Fire and Cob.  We created a gorgeous outdoor kitchen with cob oven and rocket-fired Lorena stove cooktop, counters, benches, shelving, sculptures and natural plasters, all under CCG’s signature reciprocal green roof.  This is the template for what we will do in Portugal as well.

I then prepared for teaching as Co-Instructor with my friend and colleague Tom Van Well in Puerto Rico in January and February of 2025, followed by taking the Cob Assistant position with Nicolas Pimentel in Costa Rica.  I have been avidly continuing to build and experiment with rocket stoves and heaters in my country and will be leading you with passion and excitement in creating a beautiful and unique complete outdoor kitchen as a functional art piece in Coruche, Portugal in end of Spring 2026.  I look forward to this magical time and meeting all my future students for a powerful learning and communal experience for all.. 

You too will fall in love with this beautiful world of Natural Building.
