FAQ
Before you tender
What size of project do you take on?
From about ₺150 million to ₺2.5 billion, in İstanbul and the İzmir region. Smaller restorations if the building deserves it.
Do you work on public tenders?
Yes — about a third of our work is civic, under open tender. Our work-experience certificates are available on request.
Can I visit a live site?
Every second Friday we host a site walk at Kuzey Yaka for prospective clients. Boots on, helmet provided.
How are variations priced?
In writing, before the work, from the trade’s own quote plus our agreed margin. Nothing is built on a verbal instruction.
