Kayahan Isı's story was written in Bahçelievler: from 1994 as the Demirdöküm Bahçelievler authorised service we have worked in tens of thousands of flats here. We know the district's building stock — the dense apartment blocks of Şirinevler and Yenibosna, the renewed blocks of Kocasinan and Siyavuşpaşa, the low-rise houses of Soğanlı and Zafer — at technician level.
Because our office is inside the district, most Bahçelievler calls are reached the same day, usually within hours. See also Bakırköy, Bağcılar and Güngören.
