"Bletchley Park is an urban subdivision situated within the City of Gosnells in the Southern River District in Western Australia. Within this subdivision is Castlewood Wetland (formerly Lander Swamp), which is classified as a Conservation Category Wetland. The project objective was to establish a holistic landscape proposal for the wetland and its buffer. The key concern was to incorporate and preserve the conservation values of the wetland whilst promoting active and passive recreation for the adjoining subdivision."
