PROJECT DETAILS

The city of Istanbul has lost most of its green space due to poor urban planning and unpermitted construction. In the last 50 years the population of the city has exploded, growing from 1.5 million in 1960 to more than 15 million inhabitants today. This has led to a significant deterioration in air and water quality, and an unmitigated loss of habitat. One & Ortaköy is an attempt to reclaim much-needed green space that provides a compelling example of how new construction incorporating the tenets of sustainability can increase the quality of urban life.

One & Ortaköy is constructed housing complex in the Istanbul neighborhood of Ortaköy. The project consists of two buildings: one building is private condominiums; and the other is reserved for student housing for nearby universities, managed by Republika. Nestled next to a hillside, the project is an iconic step forward in an area blighted by unplanned growth.

The One & Ortaköy project’s form, facade and overall organization were developed through a series of experimental strategies influenced by the site’s context and the desire to use every available building surface from the roofs, vertical surfaces and balconies down to the below grade spaces as opportunities to provide greenery and amenity.  

Conceived of as a green recreational area, the roof terraces include a running track, swimming pool and extensively planted gardens. These green roofs perform a number of important functions. They lessen the "heat island" effect by providing shade and an additional layer of insulation, filter pollutants, absorb and filter rainwater which is then stored and re-circulated for irrigation, and eventually will create habitat for nesting birds and flora. Visually these rooftop gardens blur the building profiles, lessening the scale of the buildings and merge them with the surrounding topography. 

A facade of regionally quarried sandstone wraps both buildings, providing a visually "soft” skin that blends with the natural hillside setting. The undulating surface treatment of the facade provides shade and opportunities for vertical plantings on alternating floors, allowing greenery to spill over balconies as hanging gardens. 

Large openings at the ground floor allow light and air into the below grade levels, and the combination of gabion stone walls and vertical garden walls transform subterranean service and recreational areas of the building into indoor/outdoor garden spaces. Mimari Proje ve Tasarım: Gökhan Avcıoğlu & GADProje Ekibi:  Ozan Ertug, Tahsin Inanici, Gizem Kiroglu, Ertugrul Morcol, Nesime Onel, Baris UcarProje Tipi :Villa, Dubleks bloklarProje Arsa Alanı :106.000 m2Proje İnşaat Alanı :36.000 m2Proje Tarihi: 2016
