Interior Architecture in Istanbul
A Guide for International Property Owners
Istanbul has become one of the most attractive cities for international property buyers, investors and companies over the past decade. Buyers from Europe, the Middle East and the United States increasingly purchase apartments, villas and commercial spaces in the city.
However, after purchasing a property in Istanbul, many international owners face the same question:
How do interior architecture and renovation projects work in Istanbul?
Interior architecture projects in Turkey are often managed differently compared to some other countries. Projects usually involve both design and construction coordination, which makes planning and project management extremely important.
This guide explains how interior architecture projects are planned and executed in Istanbul, especially for international property owners.
Interior Architecture Projects in Istanbul
Interior architecture in Istanbul typically covers:
-
apartment renovation projects
-
villa interior design and renovation
-
office fit-out projects
-
restaurant and commercial interiors
-
shell & core space completion
-
Many properties in Istanbul are delivered either unfinished (shell) or with standard developer finishes, which is why interior architecture projects are very common after property purchase.

How Interior Architecture Projects Typically Start
Most projects begin with understanding the property and the owner’s expectations.
This first stage usually includes:
-
reviewing floor plans
-
understanding lifestyle or company needs
-
identifying technical limitations
-
defining budget expectations
-
defining timeline
For international clients, this stage is often done remotely through online meetings and drawing reviews.
Design Development Process
After the initial project evaluation, the design phase begins.
This phase may include:
-
space planning and layout development
-
interior concept design and mood boards
-
material and finish selection
-
lighting design
-
custom furniture design
-
3D visualizations
This phase is important because most decisions that affect cost and timeline are made during design development.
Technical Design and Budget Planning
Once the design direction is approved, the project moves into a technical phase.
This includes:
-
technical drawings
-
electrical and lighting plans
-
mechanical coordination
-
custom furniture drawings
-
cost estimation
-
project timeline planning
At this stage, the project becomes ready for construction.
Construction and Implementation
After technical drawings are completed and the budget is approved, construction begins.
This phase may include:
-
demolition and preparation works
-
flooring and wall finishes
-
kitchen and bathroom installation
-
custom furniture production
-
lighting installation
-
painting and final finishes
This stage requires strong coordination between designers, contractors and suppliers.

This approach usually provides:

video calls from the construction site
