PTAKHAHATA
THE FIRST BUILT PILOT OF COMMON GROUND
THE CHALLENGE
Severynivka needed an educational and cultural space for women and children displaced by the war Ptakha Camp for mental rehabilitation.
The project also had to demonstrate that a small public building could use low-carbon materials, respond to its natural setting and be created with community participation.
THE PROJECT
BUDMO's winning Common Ground proposal developed a wider vision for the site.
PtakhaHata became its first built pilot: a compact pavilion for gathering, learning and observing nature, created with bio-based materials and a hands-on construction process.
01
LATEST VERIFIED MILESTONE
PtakhaHata was completed in 2025 through a participatory build involving BUDMO, volunteers and local participants.
The prize awarded to Common Ground during the 2024 Hackathon included 200 square metres of prefabricated straw-panel walls from Modulina for the project.
02
NEXT STEP
Document how the completed pilot is used and performs, and turn its technical and participatory lessons into a clear adaptation model for other small community and educational buildings.
03
PARTNERSHIP OPPORTUNITY
We welcome municipalities, donors and delivery partners interested in adapting the model, supporting post-occupancy evaluation or developing the next Common Ground building.
PROJECT 02
U-HOUSE
TRANSITIONAL ECO-HOUSING PROTOTYPE
THE CHALLENGE
Ptakha Camp needed temporary accommodation for mothers with children displaced from Ukraine's temporarily occupied territories.
The homes had to be compact, affordable and quick to build, while providing a healthy living environment. The construction process should also be accessible enough to involve volunteers and transfer practical building skills.
THE PROJECT
U-House is a compact timber-frame unit insulated with straw.
Designed as a flexible prototype, it combines low-cost construction with natural materials, volunteer participation and hands-on learning. The model can be adapted to different sites and uses rather than reproduced as a single fixed design.
01
LATEST VERIFIED MILESTONE
The first U-House unit was completed at Ptakha Camp in April 2025.
Additional U-House units were built in spring-summer 2026, and the team is continuing to replicate the model through further builds.
02
NEXT STEP
Confirm the next sites, adapt the technical package to each intended use, and secure the funding, materials and local delivery capacity required for additional buildings.
03
PARTNERSHIP OPPORTUNITY
The project is open to cooperation with municipalities and local hosts that have a defined need, as well as donors, sponsors, bio-based material suppliers, builders and practical training partners.
PROJECT 03
TEOFIPOL
GREEN WORKFORCE
HOUSING, SKILLS AND GREEN INDUSTRY AS ONE DEVELOPMENT MODEL
THE CHALLENGE
The challenge is to develop permanent, affordable and energy-efficient housing that can support the workforce of the Green Energy Industrial Park and enterprises relocating to the community, while also responding to wider local housing needs.
THE PROJECT
The project grew out of several eco-housing solutions developed during the Rebuild Green Hackathon 2024. The current development line builds on the TOLOKA concept and combines it with Modulina's bio-based construction technology, ABCU's training expertise and the Rebuild Green 2030 partner ecosystem.
It is being developed as a phased model connecting permanent housing with prefabricated bio-based construction, local skills development and the potential future production of building components in Teofipol.
Two connected workstreams are being developed:
01
TECHNICAL DEMONSTRATOR
A smaller non-residential technical demonstrator in central Teofipol would test the construction system, support Ukrainian certification and permitting, and provide verified information about cost, performance and delivery.
02
HOUSING
The first cluster for approximately 70–100 residents near the industrial park.
In the longer term, the concept could develop into a district for approximately 2,000 residents.
01
LATEST VERIFIED MILESTONE
The wider housing, training, production and community model was developed through the ReG-RURAL proposal process.
A separate REPIC application for the technical demonstrator was submitted in June 2026.
Teofipol was also presented as a Rebuild Green pilot at the Ukraine Recovery Conference 2026. Framework cooperation with Ukrfinzhytlo opened a working dialogue on possible end-user housing finance.
02
NEXT STEP
Confirm the site, land and infrastructure responsibilities; agree the roles of the municipality and consortium members; and complete the feasibility and financing package
03
PARTNERSHIP OPPORTUNITY
The project welcomes cooperation with public and development finance institutions, donors, housing providers, engineering and infrastructure partners, industrial park stakeholders.
PROJECT 04
COMMUNITY HUB & STRAW BALE TRAINING CENTRE
A COMMUNITY SPACE BUILT THROUGH PRACTICAL LEARNING
THE CHALLENGE
Communities affected by war need spaces that support social integration while creating practical skills and livelihood opportunities.
ABCU's proposal uses bio-based construction both as the method of building and as the subject of training, with particular relevance for veterans and other groups affected by the war.
THE PROJECT
The concept combines a community hub with hands-on straw-bale construction training.
It is intended as a flexible model through which community functions, practical education and the creation of physical infrastructure can be delivered as part of the same process.
01
LATEST VERIFIED MILESTONE
The ABCU proposal placed second in the 2024 Rebuild Green Hackathon.
Since then, ABCU has continued refining the concept and its delivery model, and the approach has attracted interest from several municipalities.
02
NEXT STEP
Confirm the site and local project ownership, agree the users and functional programme, assemble the implementation consortium and financing structure.
03
PARTNERSHIP OPPORTUNITY
The project requires a committed municipal host, a donor or financing partner, and material suppliers.
REBUILD GREEN 2030
Project-Specific Partnerships
Each of these four projects has reached a different stage and therefore requires a different form of support.
