Frequently asked questions

What clients ask before we start.

At which stage of a project can you get involved?

At any stage. From initial assessment and feasibility to construction drawings, site installation and commissioning, we can take responsibility from the point you need.

Can we hire you for design only or installation only?

Yes. Our services are also available separately. If we install another firm’s design, we first review it and report risks before work starts on site.

Can you work in an operating hotel?

Yes, most of our renovation and CAPEX work takes place in operating facilities. We phase works around the off-season calendar and guest flow, without stopping operations.

Which regions do you work in?

We are based in Antalya and have completed projects in Antalya, Muğla, İzmir, Afyonkarahisar and Bolu; depending on scale, we work across Türkiye.

Technical scope

Whatever stage your project is at, we can start together.
