Our build trainee programme: learning together

Global Generation has always supported young people to take social action in their local area and given them the skills they need to succeed.  With our traineeship at the #TriangleSite, we launched a structured practical learning programme focused on sustainable design and building, heritage crafts and landscaping skills. The #TriangleSite build is the very first permanent site for our charity and an opportunity for us to finally plant into the ground. We have always run community build projects that involved young people, local residents and volunteers, but after the success of working more closely with a dedicated group of young people throughout our Paper Garden build, we knew there was an opportunity to be even more intentional with this site.

Our traineeshiP: Building differently

We designed a Sustainable Build and Landscaping Traineeship, a structured, paid programme dedicated to training young people (ages 18–25) in sustainable design and building, heritage crafts and landscaping skills. Four cohorts of four young people join us for four months each during different phases of the build programme and are separated into earth building, wood & timber framing, sustainable landscaping and planting the garden. Each phase of this build programme is also supported by one of our Young Fellows - who we have trained in Action Research to support our evaluation and creative documentation.

All cohorts differ in focus, but they each engage in reflective practice, learn traditional crafts and building skills, undertake field trips, create a final showcase and learn to facilitate and lead volunteer sessions and community build days. To date, we have completed two cohorts with the third underway, what have we all learned so far?

Cohort One: Earth Building

From May  - September 2024, cohort one focused on the history and practice of cob building, exploring and experimenting with clay, water, and straw. They received specialist training from Earth Building UK and Ireland and attended ClayFest 2024 to explore different uses of cob from experts which included a tour around the brick factory and a tour of various local projects in which clay plasters and unfired clay bricks had been used, including Bellenden Nursery and a 500 year renovation of a timber frame building with clay plastered walls.

Key Achievements

  • Constructing a prototype CobBauge Wall

  • Learning how to test cob, make mixes and teaching this at facilitated cob community build days with local residents, universities, local organisations and our youth programme the generators.

  • Facilitating a Cob workshop at Build Fest 2025 and held a showcase event for partners and funders involving various workshops to demonstrate their knowledge of cob techniques

Cohort Two: Wood & Timber

From October 2024 to January 2025 cohort two specialised in traditional timber skills, including making sweet chestnut shakes and traditional timber stud walling. This cohort also stayed at Wilderness Woods to learn about coppicing sweet chestnut, and visited the Weald & Downland Living Museum to witness these crafts in numerous heritage buildings on the site.

Key Achievements

  • Learning to use shave horses, traditional carpentry tools such as froes & draw knives

  • Making a bench using traditional hand tools and building woven willow traditional East Anglian Hurdles

  • Making sweet chestnut shingles using hand techniques and cladding our kitchen building

  • Building the kitchen timber frame using UK grown timber.

CohoRt Three: Sustainable Landscaping

Currently underway, running from August - December 2026, cohort three have turned their attention to the garden, with a focus on learning about permaculture, designing and building brown roofs, building keyhole planters and planting native hedgerow. They deepened their learnings gaining a Permaculture Design Course qualification with our partner organisation Roots n Permaculture. This cohort has also visited gardens by biodiversity expert John Little and Martin Crawford’s Forest Garden at the Agroforestry Research Trust in Devon to help shape their thinking and inform their designs.

Key Achievements

  • Designing and implementing a green roof incorporating 4 different substrate mixes, composed primarily of repurposed material found on site at the Story Garden and from construction waste at the Triangle Site. 

  • Researching our forest garden: Trainees researched the height, flowering period, growing conditions, and uses of different species to ensure that we selected plants suitable to the condition of the Triangle Site. 

  • Bricklaying an accessible keyhole planter in the polytunnel

  • Auditing and selecting appropriate plants to take from the Story Garden

Tracking our impact

Since this is our first time running this format of educational programme alongside our build, we wanted to understand how it worked differently. We are working with the team from Tranquil City to evaluate the impact of the traineeship programme on the young trainees themselves. This evaluation process uses a mix of survey and interviews to understand their own feelings about their wellbeing, community and nature connection, their environmental attitudes and behaviours and their skills and knowledge development alongside their overall experiences of the programme. It follows all four cohorts from beginning to end, but some early insights from the first two cohorts have been positive. The results show that confidence after the programme is significantly boosted, more than double across both cohorts.


Reflecting & Growing: blogs by the trainees

A key part of our learning process is ongoing reflection, both individually and as a group. Each trainee is able to think deeply about what they are learning and how they feel throughout the months they work with us. We practice sharing and open dialogue in a group setting, learning from our own and others' reflections. Some of these can then take the form of stories, which we have catalogued on our website under Stories from the Build. This includes contributions from our trainees, our action researcher and other members of the wider team.

watch and LearN

We have been capturing stories and learnings all the way along and these can be seen on our Instagram and Youtube channels.

We work hard to have an inclusive site culture, open for children and families to learn together. Cassie, ex-fellow and now a member of staff, filmed a video showing the behind the scenes of one of our community build scenes. Watch more of our Sustainable Build Content.

Architecture often prioritizes speed over longevity, forgetting that buildings grow and change alongside us and the planet. Working with Global Generation, I’ve seen how time can be embraced—used to grow, teach, and create in a fast-paced city like London.
