Apartment Renovation in Istanbul
-A Guide for Foreign Property Owners-
Over the past decade, Istanbul has become one of the most attractive cities for international property buyers. Investors and homeowners from Dubai, Qatar, Europe and the United States increasingly purchase apartments in the city — either as a primary residence, a second home or a long-term investment.
However, most apartments in newly built developments or resale properties are delivered either unfinished or with standard interior specifications. For many international owners, this creates a common question:
How should an apartment renovation or interior design project be planned in Istanbul?
This guide explains how renovation projects typically work and what foreign property owners should know before starting the process.
Why Many Foreign Buyers Renovate Their Apartments
Even in luxury developments, apartments are often delivered with standard interior finishes designed for a broad market. For international owners who want a more personal or higher-quality interior, renovation becomes the natural next step.
Common reasons for renovation include:
-
adapting the layout to personal lifestyle
-
upgrading materials and finishes
-
integrating custom furniture and lighting
-
improving storage and spatial efficiency
-
aligning the apartment with international design standards
Many property owners prefer to complete this process before moving in or before renting out the property.
Popular Residential Developments Among Foreign Buyers
International buyers in Istanbul often invest in large residential developments located near the Bosphorus or in emerging urban districts.
Some well-known projects include:
-
YEDİMAVİ RESIDENCES (LINK EKLE)
-
BÜYÜKYALI ISTANBUL
-
VADISTANBUL RESIDENCES
These projects offer high-quality infrastructure, security, amenities and central locations — which makes them attractive to international property buyers.
For example, the mixed-use Emaar Square Istanbul development combines residential towers, offices and retail areas within a single large complex.
Similarly, developments such as Skyland Istanbul include residential towers with hundreds of luxury apartments integrated with offices and hotel functions.
Apartments in these types of developments often become ideal candidates for custom interior design and renovation.
Typical Apartment Renovation Process
Renovating an apartment in Istanbul usually follows a structured design and build process.
Although each project is unique, the process typically includes the following stages.
1. Initial Project Evaluation
The first step is understanding the apartment itself:
-
floor plan and spatial structure
-
building regulations
-
mechanical and technical constraints
-
renovation scope
For foreign owners, this phase often happens remotely through drawings, photos or video calls.
2. Interior Design Development
After the initial evaluation, the interior architecture phase begins.
This stage may include:
-
spatial planning and layout improvements
-
concept design and visualizations
-
material and finish selections
-
lighting and furniture planning
The goal is to create a design that fits both the apartment and the owner’s lifestyle.
3. Technical Design & Budget Planning
Once the design direction is approved, the project moves into a more technical stage.
At this point:
-
construction drawings are prepared
-
materials and custom elements are specified
-
implementation costs are estimated
This step ensures that the renovation process can proceed smoothly.
4. Construction and Implementation
During the implementation phase, contractors and craftsmen begin executing the design.
Typical renovation works include:
-
flooring replacement
-
custom joinery and cabinetry
-
kitchen and bathroom upgrades
-
lighting installations
-
wall finishes and paint
This stage requires close coordination to maintain quality and timeline.
Working With a Local Interior Architecture Firm
For foreign property owners, working with a local design team is often the most practical solution.
A local firm can:
-
manage contractors and suppliers
-
coordinate site supervision
-
ensure compliance with building management rules
-
communicate with property management and developers
This becomes particularly important in large residential complexes where renovation work must follow strict regulations.
Design + Build Approach
Many international clients prefer a design & build model, where the same team manages both design development and construction.
This approach can provide several advantages:
-
clearer communication
-
faster decision-making
-
better budget control
-
more consistent design quality

design development
-
material selection

Planning ahead helps avoid delays once construction begins.

Frequently Asked Questions (FAQ)
Can foreigners renovate their apartments in Istanbul?
Yes. Foreign property owners can renovate their apartments in Istanbul.
However, renovation projects inside residential developments usually require coordination with building management and compliance with technical regulations.
Working with a local interior architecture firm helps ensure that all procedures and approvals are handled correctly.
How long does an apartment renovation usually take?
The timeline depends on the size of the apartment and the scope of work.
Typical timeframes are:
-
Light renovation: 6–8 weeks
-
Medium renovation: 8–12 weeks
-
Large or luxury projects: 3–5 months
Projects that include custom joinery or imported materials may take longer.
Can the renovation be managed if I live abroad?
Yes. Many international property owners manage their projects remotely.
With a structured design and build process, owners can:
-
review designs digitally
-
approve materials remotely
-
receive regular site updates
-
visit the project only at key milestones
This approach is common for international clients who purchase apartments in Istanbul.
What is the typical renovation cost per square meter?
Renovation costs vary depending on design complexity, materials and technical infrastructure.
As a general reference:
-
Mid-range renovations: 900 – 1,200 € / m²
-
Upper segment projects: 1,300 – 1,700 € / m²
-
High-end luxury interiors: 1,800 € / m² and above
Actual project budgets become clear after the technical design phase is completed.
Can I hire a contractor if my design is already prepared?
Yes. If you already have an interior design project prepared, it is possible to proceed with construction and project management only.
However, the design usually needs to be technically reviewed before implementation begins.
