About Treo House

We exist for the people giving their time and energy to tackling systemic issues like climate change, nature degradation, pollution, health issues, inequality and poverty. We host a variety of intimate events that bring people together with intention; workshops, guided group discussions, speakers, film nights, book club, mentoring, suppers, wellbeing classes, adventures, retreats and more. We're all about developing the human capabilities required for systemic change; courage, curiosity, resilience, creativity, optimism... All of our events are hosted in-person in our home in Oval, London. A sanctuary in central London that allows for actual friendships and authentic conversation. Treo House is your safe place, to connect, evolve and re-energise, so you can get out there and make change happen. A brand new sustainability collective in London, opening autumn 2025.
