The concept of the mosque located in Tasik West Java is Reflection. The main concept of this mosque is to maximize the mountain and rice field view at the side of the building. Building concept is a trapezoid shape where the two ends of the building face the rice field view. A large wall is placed inside the building thus the slanted form of the trapezoid maximizes the views in the northern part of the building. When a visitor stands inside the building to perform a prayer, he/she will feel surrounded by the natural views. The walls are also ventilated. Each ventilation gap in the wall is slanted thus visitors outside are unable to see inside. A big pond surrounds the wall thus maximizing the air circulation. The mosque wall is finished with river stones as this material is commonly found around the site. The mosque looks like a part of the nature. On the façade the architect placed some calligraphies saying dawn, zuhur, asar, maghrib and isha in modern digital forms.
