Scope yours with Baily in Istanbulİstanbul tadilatınız için Baily'ye sorun, bilgileriniz on iki yabancı müteahhite dağıtılmayacak. İstanbul, dünyanın en karmaşık tadilat piyasalarından biridir. Beşiktaş'taki 1960'ların apartman dairesi, Nişantaşı'ndaki Art Nouveau konağı, Bebek'teki Boğaz manzaralı villa, Cihangir'deki 19. yüzyıl ahşap İstanbul evi, Moda'daki 1930 Kadıköy apartmanı ve Levent'teki 2015 sonrası gökdelen dairesi — her mülk tipi farklı uzmanlık, farklı yetki belgesi, farklı mühendislik kabul süreci ve Marmara Depremi ardından getirilen farklı sismik güçlendirme gereksinimleri gerektirir. Armut ve Yandex Hizmet gibi platformlar talebinizi on iki müteahhite SMS ile gönderir; çoğu geçerli İnşaat Müteahhitlik Yetki Belge Numarası (YBN) bile taşımaz. Baily farklı çalışır. Tam yerel bağlamı — YBN sınıfı, TMMOB İnşaat Mühendisleri Odası kayıtları, Kentsel Dönüşüm 6306 sayılı kanun teşvikleri, 1999 sismik güçlendirme yükümlülükleri, ve Boğaziçi Koruma Kanunu kısıtlamaları — elinde tutar ve size mülkünüze, kapsamınıza ve bütçenize uygun bir İstanbul müteahhidi tanıtır. Tek bir profesyonel, bir ev sahibi, başlangıçtan kusurlu sorumluluk dönemi bitişine kadar.
