Nammuldi Below Water Table (NBWT) Village Landscaping

Scope of Work & Disciplines

The Nammuldi Below Water Table (NBWT) Village Landscaping comprised design, supply and installation of reticulation, screening & feature trees, ornamental concepts, shrubs and low level planting, turf lawn, paving and an array of landscaping treatments to enhance the village and user experiences all year round.

The design considered key elements of colour, space, shade and pathway definition without disguising or disrupting the function of buildings and structures.

Pindari created green zones with upcycled iron sculptures around gazebos for social interaction and seclusion as well as open spaces in the village for leisure or passive recreation. Indigenous arts featured in the accommodation zones to disguise service corridors, manage pedestrian traffic and soften building lines while preserving access to services.

Screening trees aesthetically frame the village frontage, provide shading and complimenting the village entry landscaping treatments which included a night lit meeting place and bushtucker garden.

Landscaping and planting defined paths and verandas that encourage residents to use the existing pedestrian access and control traffic around turf lawn areas.

The planting softened all aspects of the central facilities (kitchen-diner and tavern-beer garden/cafe recreation, gymnasium complex) and the view looking out from within the central facilities and from the footpaths was no longer of the service yards. The area was also made more functional with a large concrete hardstand featuring a meeting place design defining the designated smoking area.
