Landscape Architecture

Changing our environment for the better.

Our award-winning Landscape Architecture team has been operating for over 20 years. We have a wide range of expertise for a variety of scales and types of projects.

Our design philosophy is to make places for people. It seems like a simple concept, but we consider the delicate balance between the natural world and everyone who lives within it fundamental to the outcomes we produce. We apply that understanding to each unique project we work with to design spaces we can all be proud to enjoy with our families.

Our landscape architects work within our Urban Design team and work closely with our colleagues in other disciplines. Whether you are after a one- stop shop for projects, or require our inputs to complement your existing team, we can help you out with:

  • Residential and commercial subdivisions
  • High profile streetscapes and plaza’s
  • Wayfinding, pedestrian and cycle networks and transportation hubs
  • Ponds, wetlands and native re-generation projects
  • Plaza’s, parks and reserves
  • Iwi story-telling and collaboration
  • Playgrounds
  • Private homes and lifestyle blocks
  • Landscape and visual effects assessments
