The initial stages of construction implementation begin with planning, implementation, and operation. From each stage of the project must be with a green or environmentally friendly concept. Eco-friendly planning in residential buildings starts from the use of building materials, energy-efficient design concepts, and economical development costs. In addition, the construction of houses must also pay attention to health, such as ventilation, garbage disposal, and the provision of green environments for plants. The costs analyzed in this study refer to environmentally friendly concepts that can be applied to the construction of residential houses. Residential buildings in urban areas generally have narrow land, so that the 1st floor building built is with an area of 36 m2, 45 m2, or 60 m2. The object of research in this case is building housing built by developers in general. As for the results of field observations, that environmentally friendly concepts that can be used are land arrangement, energy saving, healthy homes, and the use of environmentally friendly materials. Design modifications from existing conditions are the addition of loster, glassblock, the use of red brick, mild steel, and modification of water taps.
