Torhaven is a masterplanned residential community developed by Defence Housing Australia in the rapidly expanding suburb of Deebing Heights.  Located in close proximity to the City of Ipswich and RAAF Base Amberley, the development spans over 27 hectares and comprises 296 lots.

With a vision to create healthy and sustainable communities for defence families, the project has implemented new housing methods and sustainable practices whilst fostering an active and interconnected community.

ACOR undertook civil engineering for the whole site and worked with the team to replace traditional bio-retention stormwater systems with an ephemeral wetland that retains the land’s slope and existing watercourse.

While dormant for extended dry periods, the wetlands can accommodate torrential run-off from the Torhaven estate and 45 hectares of surrounding areas, removing pollutants naturally before the water flows back into the local Deebing Creek waterway.

Avoiding the creation of a large, unusable space with bio-retention drain, the 2.2 hectare area has been landscaped to incorporate a creek-like catchment integrated with community recreation facilities and rich with biodiversity.
