The Ghana Real Estate Developers Association (GREDA) and the Social Security and National Insurance Trust (SSNIT) have warned encroachers on the government-acquired land at Dunkonah to remove their structures before March 31. They should also evacuate their workers, machinery and materials from the land. A statement issued by the National Housing Project Committee on Dunkonah said illegal structures found on the land after the deadline would be demolished and owners surcharged with the cost of the exercise, including the disposal of debris. The land is about 16 kilometres from Accra on the Accra- Winneba road and adjoins the Vanderpuye-Orgle Estates lands.
