Villa and Property Renovation in Istanbul for International Buyers: Kemer Country, Büyükçekmece, the Bosphorus and Beyond
Purchasing a villa or house in Turkey is one of the most significant investments an international buyer can make. Whether you are acquiring a property for personal use, as a second home, or as part of a Turkish citizenship by investment programme, the moment the keys are handed over, a new set of decisions begins.
How do you bring the property up to the standard you expect? Who manages the renovation while you are in Dubai, Baku, Moscow or London? How do you ensure the work is done correctly, on budget, and without you needing to be present in Istanbul every week?
These are the questions Sonraki Architecture answers — every day, for property owners based across the Gulf states, Azerbaijan, Russia, Central Asia, and Europe.
Since 2014, we have delivered interior design, renovation and fit-out projects across Istanbul and beyond — managing the entire process from first site visit to final handover, on behalf of owners who trust us to get it right while they are elsewhere in the world.
Where International Buyers Purchase Property in Turkey
International buyers acquire residential property across a range of locations in Turkey, each with its own profile, price point and renovation characteristics.
The Bosphorus — Istanbul's Most Prestigious Address for International Buyers The Bosphorus waterfront is where Istanbul's highest-value international property transactions happen. Gulf buyers, Russian investors and European nationals with long-standing connections to Turkey have historically been drawn to yalıs — the traditional Ottoman waterfront mansions that line the Bosphorus in neighbourhoods such as Bebek, Arnavutköy, Tarabya, Yeniköy, Kandilli and Çubuklu. These properties represent some of the most complex renovation commissions in Turkey: heritage structures requiring sensitive architectural intervention, structural renewal, full MEP replacement and complete interior redesign — all within the constraints of historic preservation regulations.
Beyond the yalıs, the Bosphorus corridor also includes premium apartment buildings in Bebek, Etiler and Nişantaşı where international buyers acquire high-specification residences that nonetheless require interior design and renovation to meet personal standards.
Renovating on the Bosphorus demands a firm that understands both the regulatory environment — particularly the coastal zone and historic preservation requirements — and the material and craft standards expected at this level. Sonraki has the experience and the network to deliver this.
Istanbul — European Side coastal corridor (Ataköy, Büyükçekmece, Beylikdüzü) The E-5 and coastal road corridor along the Sea of Marmara attracts significant interest from Gulf and Middle Eastern buyers, particularly those seeking larger villa-type properties with sea proximity. Developments along the Büyükçekmece shoreline and the Ataköy districts offer established residential stock at a range of price points, with many properties now requiring interior modernisation.
Istanbul — Premium managed residences (Zorlu Center, Emaar Square, Büyükyalı) International buyers seeking branded, managed developments gravitate toward these addresses. The renovation and interior design requirements here are covered in our dedicated guide: Apartment Renovation in Zorlu Center, Emaar and Ataköy
Kemer Country, Acarkent and established villa sites While these addresses are primarily occupied by Turkish owners, they occasionally attract international buyers seeking established, high-security villa communities close to Istanbul. The renovation profile here is substantial — most stock is 20–30 years old and requires comprehensive infrastructure renewal before it meets modern living standards.
Sapanca, Adapazarı and the wider Marmara region Sapanca Lake and its surroundings have become increasingly popular with buyers from the Gulf states, Russia and Azerbaijan seeking large private properties in a natural setting within two hours of Istanbul. These properties often arrive with significant renovation requirements — from basic infrastructure to complete interior design.
Bodrum, Ankara, Bursa and other major cities Sonraki works across Turkey, not only in Istanbul. International buyers acquiring property in Ankara, Bursa or other major cities can access the same full-scope design and build service.
What Makes Renovation in Turkey Different for International Buyers
Renovating a property in Turkey while living abroad presents a specific set of challenges that do not exist when working in your home country.
Language and communication Most Turkish contractors, suppliers and tradespeople operate exclusively in Turkish. Without a bilingual, professionally structured project team managing the process, international owners find themselves unable to monitor progress effectively or intervene when problems arise.
Building permits and local regulations Structural changes, extensions and certain technical works require municipal permits in Turkey. The process varies significantly by municipality and property type. Without local expertise, international buyers frequently encounter delays or — more seriously — complete unlicensed works that create legal complications at resale.
Quality control without physical presence The gap between what is agreed and what is delivered can be significant in the Turkish construction market without rigorous on-site supervision. International owners who cannot visit frequently are particularly exposed to this risk.
Material and supply chain management Premium finishes, European-standard fixtures and bespoke joinery require sourcing expertise. Sonraki's established network of Turkish and European suppliers ensures material quality is not compromised to meet a local contractor's convenience.
Currency and payment structure International buyers often prefer to transact in USD or EUR. Sonraki structures project contracts clearly, with milestone-based payment schedules that align with verifiable progress — not arbitrary dates.
The Bosphorus — Istanbul's Most Demanding Renovation Environment
The Bosphorus waterfront is not only Istanbul's most prestigious residential address — it is also its most technically and regulatory complex renovation environment.
Yalıs and historic waterfront properties Yalıs — the historic Ottoman timber mansions that line the Bosphorus — are among the most coveted residential properties in Turkey for discerning international buyers. Gulf families, Russian investors and European buyers with deep connections to Turkey have long recognised the yalı as an irreplaceable asset: unique architecture, direct Bosphorus frontage, and a cultural heritage that no new-build development can replicate.
Renovating a yalı, however, is a genuinely specialist undertaking. These structures are subject to coastal zone regulations, historic preservation requirements and structural constraints that demand experienced architectural and engineering input from the very first day of the project. Foundation stabilisation, timber structure renewal, moisture management — particularly for below-waterline sections — MEP replacement within heritage fabric, and the sourcing of period-appropriate materials are all standard requirements.
Sonraki works with specialist conservation engineers and architects where required, integrating their expertise into a unified design and build delivery. The result is a property that honours its architectural heritage while performing to contemporary living standards.
Premium Bosphorus apartments — Bebek, Etiler, Nişantaşı, Arnavutköy Beyond the yalıs, the Bosphorus corridor includes a significant stock of premium apartment buildings in Bebek, Etiler, Nişantaşı and Arnavutköy where international buyers — often purchasing as a pied-à-terre or second home — require complete interior design and renovation to their personal standard.
These properties typically involve: full spatial redesign, premium material specification, bespoke joinery and furniture production, smart home integration, and coordination with building management where applicable.
Alkent Etiler — Alarko Holding's landmark 1989 development with 652 units — is one of the most established addresses on the western Bosphorus corridor. Its mature residential stock, central location and upper-income owner profile make it a natural fit for Sonraki's full-scope interior design and renovation service.
Büyükçekmece and the Sea of Marmara Corridor
The Büyükçekmece district on Istanbul's western European side has seen consistent interest from Gulf, Russian and Central Asian buyers. The combination of sea proximity, large plot sizes and relatively accessible property prices makes this corridor attractive for buyers seeking a permanent residence, a second home, or a property qualifying for Turkish citizenship by investment.
The residential stock here ranges from established villa sites to newer developments, with renovation requirements varying accordingly. Older properties in this corridor often require:
-
Full electrical rewiring and panel upgrades
-
Plumbing replacement and boiler renewal
-
Kitchen and bathroom modernisation to European standards
-
Insulation improvements — both thermal and acoustic
-
Interior design from scratch, including spatial planning and bespoke furniture
Sonraki has completed projects in the Ataköy and western Istanbul corridor and is fully equipped to manage commissions in Büyükçekmece and surrounding areas.
Kemer Country — For the International Buyer
Kemer Country in Göktürk, close to Istanbul's new airport, is one of Istanbul's most established private villa communities. Occasionally purchased by international buyers — particularly those with Turkish business connections or long-term residence plans — the Kemer Country stock presents significant renovation potential.
Villas here typically range from 400 to 800 m² on generous plots. Most were built between the 1990s and early 2000s and require full infrastructure renewal: electrical systems, plumbing, HVAC, smart home integration and complete interior redesign.
Sonraki manages this scope of work entirely in-house — from technical assessment and design through to bespoke joinery production and final handover. For an international buyer, this means one point of contact, one contract, and structured digital reporting throughout.
Sapanca and the Greater Marmara Region
Sapanca Lake, approximately 130 kilometres east of Istanbul, has emerged as one of Turkey's most sought-after locations for international buyers seeking large private properties in a natural setting. Gulf buyers in particular have shown strong interest in the Sapanca region — attracted by the lakeside setting, clean air, privacy and the ability to acquire properties significantly larger than what is available in Istanbul for equivalent investment.
Properties in the Sapanca region often require comprehensive renovation: many were built as weekend retreats and lack the infrastructure required for year-round primary or secondary residence use. Full interior architecture, technical infrastructure renewal, smart home integration and landscaping coordination are common requirements.
Sonraki manages projects in the Sapanca region with the same structured remote project management approach applied to Istanbul commissions.
How Sonraki Manages Your Turkish Property Renovation Remotely
For international property owners, the Sonraki process is structured to require minimal physical presence while maintaining full transparency and control.
Step 1 — Remote Initial Consultation A video call to understand your property, your vision, your timeline and your budget. We can review floor plans and existing photographs to give you an initial project assessment before any commitment.
Step 2 — Site Visit and Technical Assessment Sonraki visits the property on your behalf. We assess the structural condition, existing infrastructure, access constraints and scope of works required. A written assessment is shared with you digitally.
Step 3 — Interior Design Concept and Technical Documentation Spatial planning, 3D visualisations, material selections and complete technical drawings are prepared. Nothing proceeds to site without a fully documented project behind it. More on our process: How Does the Fit-Out Process Work?
Step 4 — Bespoke Production and Material Procurement Fixed and loose furniture, joinery, kitchen systems and all specified materials are sourced and produced through Sonraki's established network. Our production capability: Interior Manufacturing and Supply
Step 5 — Construction and Site Management All trades are coordinated by Sonraki. Weekly progress reports, site photographs and video walkthroughs are provided. You are informed of every significant decision before it is implemented.
Step 6 — Finishing, Styling and Handover Decoration, loose furniture placement and interior styling complete the project. You receive a finished, move-in-ready property.

Project Costs for International Buyers in Turkey
As a general reference for renovation and interior design projects across Istanbul and the wider Turkey market:
-
Surface renovation with furniture and technical upgrades: approximately €900 – €1,300 / m²
-
Comprehensive renovation including infrastructure renewal and full interior design: approximately €1,300 – €1,800 / m²
-
Bespoke specification, premium materials and high-detail projects: €1,800 / m² and above
For Bosphorus yalıs and large waterfront properties, project budgets vary considerably depending on the structural condition of the building and the scope of heritage intervention required. These projects are assessed individually.
For Kemer Country and Acarkent scale villas (500–1,000 m²), total project budgets typically range from $500,000 to $2,000,000 depending on scope and specification.
For Büyükçekmece and Sapanca properties, costs depend significantly on the current condition of the infrastructure and the extent of works required.
All costs are confirmed following site assessment and project scope definition. No commitment is required before this stage. More on pricing: Interior Design and Implementation
Frequently Asked Questions
Do I need to be in Turkey during the renovation?
No. Sonraki is specifically structured for remote clients. You will receive regular structured updates — site photographs, video walkthroughs, written milestone reports — throughout the project. Physical visits are welcome at any stage but are not required.
I am interested in a Bosphorus yalı. Are these genuinely manageable as renovation projects?
Yes — but they require a firm with specific experience in heritage structures and coastal zone regulations. Sonraki works with conservation specialists where required and manages the full scope under one contract. A pre-purchase assessment is strongly recommended before committing to a yalı acquisition.
How do I know the work will be done correctly if I am not there?
Sonraki operates as both designer and principal contractor — which means we hold full accountability for the outcome, not just the design. Our project manager is on site regularly throughout construction, and all progress is documented and shared with you.
Can Sonraki help me assess a property before I purchase it?
Yes. We offer pre-purchase property assessments — visiting the property, evaluating its condition and renovation potential, and providing a written report with indicative costs. This is one of the most valuable services we offer to international buyers making purchase decisions remotely.
Does Sonraki work outside Istanbul?
Yes. We have completed projects in Bursa and work across the wider Turkey market. Sapanca, Adapazarı and similar locations within the greater Marmara region are within our project scope.
Can I commission Sonraki for loose furniture selection only — without a full renovation?
Yes. We offer interior design consultancy, loose furniture selection and placement, and interior styling as standalone services. Not every project requires a full construction programme.
What languages does Sonraki work in?
Project communication is conducted in Turkish and English. We regularly work with clients from the Gulf states, Azerbaijan, Russia and across Europe.
Can I only hire a company for construction if I already have a design?
Yes. Existing designs can be reviewed technically and construction and project management services can be provided separately.
