Halcyon is committed to delivering best-in-class residential developments with a focus on the co-living sector. We have delivered over 800 co-living units in London since 2022, with a secured pipeline of over 1,400 units.

We work with a handful of valued partners and meaningfully engage with all stakeholders in order to deliver balanced outcomes.

Our Approach

Enable Flourishing Communities

Halcyon listens to and engages with all stakeholders, including those local to our projects to deliver maximum local impact. Our buildings, and their construction, are designed and managed to minimise impact. The final outcome being low-impact buildings which provide a future for people to live, work, play and thrive.



Halcyon believes in building long-term trust and collaboration by being accountable for the decisions it makes, transparent with stakeholders and committed to maintaining and improving its relationships throughout the delivery of a project. We pride ourselves on being measured against the final product and financial, social and environmental benchmarks.


Institutional Excellence

Halcyon combines the agility of a small company with institutional grade excellence. We find sites, take them through planning, design and deliver them. We approach all stages with rigour, control and consistent critical analysis.
