HOUSE

SUSTAINABILITY

COLLECTIVE LONDON

WE
ARE

A COLLECTIVE OF PEOPLE

WORKING TO CREATE A HEALTHIER, KINDER & FAIRER FUTURE

GATHERING IN AN OLD PICKLE FACTORY IN LONDON

TO LEARN FROM & SUPPORT EACH OTHER

COLLABORATING FOR REAL CHANGE

DOING THINGS DIFFERENTLY

WHY
WE
EXIST

WE ARE FALLING SHORT ON SUSTAINABILITY PROGESS

Despite many excellent people giving their time and energy to environmental and social impact work.

BECAUSE CREATING CHANGE IS TOUGH

Problems like climate change, nature loss and inequality are complex, systemic, unprecedented, urgent & consequential.

We are genuinely impassioned by the problems and know that

COLLABORATION IS ESSENTIAL.

WHAT WE DO

WE GATHER AND FACILITATE TO...

01.

LEARN FROM
EACH OTHER

No individual knows all of the answers to our sustainability problems, but between us we have so many experiences, learnings and ideas to share. 

02.

LOOK AFTER
EACH OTHER

Sometimes this work can feel overwhelming and lonely. We make sure to look after ourselves and each other so we can approach this from a place of health, joy and balance.

03.

MAKE CHANGE HAPPEN

By strengthening our members' existing work and kick-starting new projects, we bring people together to do the work that needs to be done.

​"FEELING QUITE REVITILISED"

"It's a great collection of people and the most authentic and open discussion I’ve had with others about sustainability. Feeling quite revitalised on the topic now."

DOING IT
DIFFERENTLY

OWNED BY NO ONE, SHARED BY EVERYONE

We have no shareholders and any profit is directly re-invested into the organisation.​

CO-DESIGNED AND RUN BY MEMBERS

Treo House is a co-creation of it's members, collectively building the organisation that we need it to be.​

REAL PEOPLE, IN PERSON

We focus on people's ideas and passions rather than job titles and status. ​​​

NOT CONFUSING EFFORT WITH IMPACT​

We don't measure our success as bums on seats, social media likes or the number of events hosted.​

TREO

Derived from the Old English word for Tree.
Trees are our greatest teachers in
collaboration and collective survival.
And who doesn't want to hang out in a tree house?
