Maraylya development:
Abax Contracting

Residential Subdivision, August 2018


Our customer Abax Contracting is working on early site preparation and subdivision for new residential land releases at Maraylya in the Hawkesbury region. Abax Contracting are specialists in land acquisition, development and civil contracting.

The land releases are part of The Box Hill North Precinct which council zoned for urban development back in 2015. Included in this subdivision was a residential zone consisting of over 600 lots.


Located in the semi-rural areas of Maraylya and Box Hill, The Hills Estate and Highgrove at Box Hill are two new residential developments. The development plan for the area stated that dwellings must have a high standard of aesthetic quality for both new occupants and the existing residents of the area. The project managers were therefore obligated to fit these new developments into the rural landscape setting, whilst still providing for a modern residential lifestyle.

Consequently, Abax worked to retain the green spaces and rural charm of the area so that the end product would be an attractive estate well suited to the area.


During the initial subdivision works, Abax chose a range of quality precast concrete pits, grates, lintels and kerb components from Jaybro. These provided a high-quality finish to the kerbs and utility access areas in keeping with the high standards of the overall development.


  • Precast lintels and kerb gully grates
  • Precast pits and risers
  • Grates and covers
  • Kerb adaptors
