Dam Niyamgama is located in the district of Kalutara, about five kilometers from the sea on a piece of land granted by the government. Placed on a gentle five-acre slope bordering rice fields, the village is compose of fifty-five eco-friendly houses, a multi-purpose community center, ample water resources, a comprehensive road network, and expansive green areas. The Austrian Study Center for Peace and Conflict Resolution (ASPR), through their local partner Sarvodaya, reconstructed this village with the generous funds from the Austrian province of Burgenland.

Each house has 500 square feet and consists of two bedrooms, a living room, a kitchen, and sanitation facilities. The houses were built according to the UNEP guidelines for construction of eco-houses in Tsunami-affected areas in Asia. The houses and the community center are provided with electricity through solar panels. Fourteen rainwater harvesting tanks, five drinking wells, and two bathing wells have also been erected in the village. The project has established a Subterra system, a natural method for wastewater treatment, and set up a recycling process for solid waste material.
