She has expertise in a broad range of projects types from strategy and masterplanning, to the design conceptualisation and development, through to preparation of construction documentation. Sarah can move from large scale complex masterplans to intricate spaces that knit into urban fabric, to natural elemental environments – bringing the same level of design sensitivity, clarity and refinement.

Recent projects have included masterplanning for urban centres and coastal environments; the design and delivery of public parks, plazas and streetscapes. She works collaboratively with public and private sector clients, stakeholder and community groups to deliver high quality outcomes loved by their communities.

Sarah’s interest in urban renewal projects, particularly where the land meets the sea is informed by a fascination with maps and their language of how our towns and cities evolve.

Scott has experience working on a wide range of landscapes including public realm, infrastructure ecological corridors, apartment gardens, 16th century park redevelopments and residential masterplans. He is passionate about designing from concept to completion and specialises in landscape construction detailing and innovation with a strong interest in concrete.

He sees landscape architecture as an opportunity to connect people with the land and recognises that we have a special role in bringing people of different cultures and backgrounds outside into our outdoor environments. The recreation of the natural environment in urban spaces and re-interpreting natural processes in a city context is an underlying theme throughout many of Scott’s projects.
