The mosque serves as a place where Muslims can come together for salat (prayer) as well as a center for information, education and dispute settlement.

In the Ottoman urban texture, a city square is not found as in the European cities. The Mosque and mosque courtyard relatively serves as a city square. Mosques with their social complexes are the center of social life.

Apart from their plan metric assembly due to masonry construction, we can observe from the point of geometric forms that minarets provide a visual focal point not domes. Domes are also take part in Turkish bath’s, tombs, markets and similar buildings.

Ottoman Mosques having circular geometry, multi-directional, illuminated, a sanctuary of esthetic, technical balance and a hint of heavenly transcendence spaces contrast with the church architecture being rectangular, unidirectional, dogmatic, scary and dark.

The aim of gathering grater amount of people under one space is obtained in the central domed examples by articulating building units with construction capabilities of the era. Formed by structural aggregation, perceptional meaning of central spaces coincide with the idea of existence as combining of all the parts, elements and individuals into an effective whole. Domes’ seamless spatial effect identify with the existence of universe, minarets symbolize as a religious communication antenna. Construction technique, architectural space and meaning become integrated.

Yesil Vadi Mosque is designed from functions emphasized, identifying components; bearing in mind all these traditional, spatial, semantic criteria’s and also taking to heart the mosque image in the communal memory.

Mosque schedule formed in the context of “social gathering” is made up of 350 person prayer area, 250 person meeting hall, library, social activity units, courtyard and square forms a social complex.

Main structure of the mosque is placed on a water surface covering half of the site. This positioning isolates the building from the environment functionally and symbolically.

Central space and form of the mosque is obtained by subtractions from a 25 m diameter mass hemisphere. A 2.5 m thick spherical piece subtracted from half of the hemisphere forms gathering-place, emptying a section sphere forms the last prayers area, subtraction of a vertical piece forms the cap stone gate and entrance, subtraction of shell like piece mihrab (a niche in the wall of a mosque that indicates the qibla/ direction of the Kaaba in Mecca) and subtraction of smaller shell pieces windows are formed.

Contrary to geometry of dome, minaret is formed by joining a paraboloid cone to a cylinder. Smaller cylinders aggregated together form cone, crescent and gallery (balcony which encircles the upper sections from which the muezzin may give the call to prayer).

Main space of concrete shell is defined by two different diameter hemisphere domes. The circular opening between two domes is divided by 11 (33, 99 religious directory) illuminated windows. These windows flow light to main space through engraved symmetric kufic calligraphy of prayers. Calligraphy reflects over interior of the dome, this windows form a crown like lighting at night.

Main space takes in light from 3 stepped windows, subtraction of shell like piece mihrab takes in light from rear and top windows. Mihrab is emphasized with engraved symmetric kufic calligraphy “Basmala” an Arabic noun that is used as the collective name of the whole of the recurring Islamic phrase “In the name of God, Most Gracious, Most Merciful” (b-ismi-llahi r-rahmani r-rahim).

Main gate made of stainless steel and glass sliding doors, is marked with geometric marble muqarnas forms.

Minaret positioned detached from the main structure, is sized according to the golden ratio for the scale of architectural proportion and all sizes of elements is connected to these scales.

The gallery, cap and crescent is made up of 20 cm diameter stainless steel cylinder tubes. These muqarnas like tubes illuminate the minaret and the gallery with fiber optic lighting elements below. The cap of the minaret has a 4 way surround speaker system for calling to prayer.

Additional building forms a platform having wide gargoyle flow water down. Water element covering half of the courtyard symbolizes life and being alive as for marble covering symbolizes stability and death. Concrete console structure placed in between two musalla stones (space outside a mosque that is mainly used for funerary area).This console is engraved with Sura Al-Fatiha is the first chapter of the Muslim holy book, the Qur’an. In abstract and physical basis life, time and death sequence is symbolized.

Yesil Vadi Mosque positioned according to master plan data’s in the new settlement area is planned by our office. Yesil Vadi Housing Settlement containing housing blocks, shops, social facilities and sports center, elementary school forms a neighborhood.
