THIRTYTHREETREES LIMITED

Thirtythreetrees Ltd. is a Dublin‑based practice of landscape architecture, founded in 2004 with a clear mission to champion the cultural and environmental relevance of landscape design. Drawing on the belief that architecture, landscape and gardening are inseparable, the studio delivers thoughtfully crafted outdoor spaces that respond to both site and community.

The firm specialises in a wide range of services, from master‑planning and garden design to the realisation of complex built works. Its portfolio includes notable projects such as the Howth coastal promenade, the Sligo civic precinct, the revitalised Merrion Square, the Henry J Lyons development, and the award‑winning CAT‑ONE™ installation. Thirtythreetrees also engages with the wider architectural discourse, regularly exhibiting at events such as the RIAI Awards Exhibition, Open House Dublin, the Venice Architecture Biennale and the EU Prize for Contemporary Architecture.

With a reputation for high‑quality, context‑sensitive design, Thirtythreetrees serves public bodies, private developers and individual clients who seek innovative, sustainable landscapes that enrich the built environment. Their work is recognised across Ireland and
