Marina Residences Istanbul: Beylikduzu Guide (2026)

This page lists the project under the name Marina Residences Istanbul; the developer’s official project name is Yaşam Marina, a scheme in Beylikdüzü on the European side of Istanbul, developed by Lionia Yapı and Partners according to its own site. The identification rests on matching plan sizes and entry prices with a broker listing and is rated high. This guide sets out what the developer publishes, what only agents state, which figures conflict and what to request in writing. Every rule and rate below carries the date 24 October 2026.

Overview of Marina Residences Istanbul

The developer’s project story page describes a scheme close to the sea in Beylikdüzü, planned for families: pools, green areas, tennis and basketball courts, playgrounds, restaurants and cafés, a Turkish bath and an open-air shopping centre, in apartments from 2+1 to 5+2. It also mentions a smart-home concept and a reinforced foundation with C30/C35 concrete. This is the developer’s own wording and is not confirmed independently here.

The developer’s pages (home, story, concept, floor plans and contact, read on 24 October 2026) publish no completion status, delivery date, unit count, plot area, price, licence or permit number, or title-deed information. The home page holds a slogan and a menu only.

Agent pages fill the gap, and they conflict. The Skyline Holding listing shows a delivery date of 20 November 2024, five blocks, 300 homes plus 40 commercial units and 40,000 m² of land, and marks the project ready.

An Emlak34 listing on port724.com labels it “Hemen Teslim” (immediate delivery), counts 320 homes plus 40 commercial units in its text but 300 homes in its feature list, and prints a plot of 37,940 m² in its header against 40,000 m² in its body. These are agent figures, not developer statements or permits.

The card on this site shows entry prices of USD 260,000 (2+1, 125 m²), USD 353,000 (3+1, 175 m²) and USD 496,000 (4+1, 225 m²), per our listing card, as of 24 October 2026. The card is a broker feed last edited on 26 August 2026, and its prices lie within 1% of the Skyline snapshot (USD 260,000, 351,000 and 495,000).

The Türkiye country page and the Istanbul city page give the wider context.

Unit types and sizes at Marina Residences Istanbul

The developer’s floor-plan page lists four plans: a 2+1 of 125 m², two 3+1 plans of 165 and 175 m², and a 4+1 of 225 m². It does not say whether the areas are gross or net, and it gives no count per type. The approved architectural project filed for unit ownership states each unit’s construction area (Condominium Law 634, Article 12), so that document settles the question.

The story page widens the range to 2+1 through 5+2 and 125 to 375 m², but no plan is shown for a 5+2 or for any home above 225 m²: the top of the stated range is 1.67 times the largest plan (375 divided by 225).

The card repeats three of the four plans and leaves out the 165 m² 3+1. The Skyline snapshot lists areas that differ by 5 to 10 m² on every type. The table sets the three sources side by side and adds the entry price per square metre, calculated from the card at USD 1 = TRY 49.6540 (CBRT forex selling rate, bulletin 2026/201 of 23 October 2026).

Three readings follow, each calculated from the table. The card prices per square metre differ by 9.3% between the cheapest type (3+1) and the dearest (4+1). The Skyline figures give USD 1,950 to 2,167 per square metre, so the two broker sources do not describe identical areas. And a 5 to 10 m² gap on the same type is large enough that the area definition (gross with balcony share, or net) has to be fixed in writing before any price is compared.

On the citizenship threshold, the regulation text reads as follows as of 24 October 2026: Article 20(2)(b) of the Citizenship Regulation sets USD 400,000, after Decision 5554 (Resmî Gazete 13 May 2022, no. 31834), and Decision 7938 (Resmî Gazete 12 December 2023, no. 32397) narrowed the property type to units with kat mülkiyeti or kat irtifakı and to plots carrying a building.

The three card entries are 65.0%, 88.3% and 124.0% of USD 400,000. That comparison puts a broker price next to a legal figure and does not show that any unit is accepted: the value is the one in the valuation report, the purchase price and payment method are examined, a three-year no-sale annotation applies, and the authorities decide. See the citizenship and immigration page for the programme.

What to request in writing about unit types

• The gross and net area of every unit, with the balcony and terrace areas stated separately, as shown in the approved architectural project.
• Whether the 165 m² and 175 m² 3+1 plans are both on sale and which floors and blocks each belongs to.
• Whether any 5+2 or home above 225 m² exists, and a plan for it, since the story page gives up to 375 m².
• Floor, block, orientation and the sea-view claim for the specific unit, with the plot in front of it identified on the zoning plan.
• What is inside the price: parking space, storage room, kitchen and wardrobes, the smart-home equipment, VAT.
• The areas and use of the 40 commercial units that agents mention, and whether they are separate independent sections.

Location of Marina Residences Istanbul: Beylikdüzü, the Marmara coast and the marina

Beylikdüzü lies on the European side of Istanbul, on the northern shore of the Sea of Marmara. Law 5747 (accepted 6 March 2008, Resmî Gazete 22 March 2008, no. 26824 repeated) created the district with ten neighbourhoods, three of which matter here: Marmara, Kavaklı and Adnan Kahveci. Wikipedia gives 415,290 residents for 2024 and an aggregator quotes 422,988 for 2025, both citing TÜİK; the table on the TÜİK data portal could not be opened for this guide.

All three names are attached to the scheme. The developer’s contact page places its office in Marmara Mahallesi, port724 says “Yakuplu, Marmara Mah.”, and Skyline says Adnan Kahveci. The card’s map pin (40.98189 N, 28.66131 E) falls on a road that OpenStreetMap places in Kavaklı Mahallesi, next to Marmara. No parcel number is published. The block (ada) and parcel (parsel) in the title register identify the land, not a neighbourhood label, so they should be obtained before any distance on this page is relied on.

The marina anchors the developer’s location text. The West Istanbul Marina site gives N 40°57′46″ E 28°39′49″ and says it can berth up to 600 yachts; its layout lists a beach club, restaurants and bars, a fitness and spa building, sports courts, an amphitheatre and a heliport.

The developer’s story page puts the scheme 1.2 km from the marina and its concept page says 5 minutes, without a mode of travel. From the card pin the marina is 2.1 km away in a straight line and 3.1 km by road. A mapped point of Kocatepe Caddesi, the street on the contact page, lies 1.4 km from the marina, so the 1.2 km may be measured from the project boundary; the parcel will settle it.

The developer mentions metrobus stops without naming them. The metrobus reached the Beylikdüzü Sondurak station on 19 July 2012 according to Wikipedia, and İETT (iett.istanbul) runs the line. The Beylikdüzü stop mapped by OpenStreetMap is 2.9 km from the pin in a straight line and 4.2 km by road. The concept page also lists “15 minutes walking to 2023 METRO underground system”, a location “in the middle of the 3rd Airport and the 2023 Metro”, and Kanal Istanbul; none comes with a line name or a date.

The only metro project found for the district is the Sefaköy-Beylikdüzü-TÜYAP line (M20): about 18.5 km and 10 stations. Taşıma Dünyası reported on 27 June 2024 that the ministry approved the project in July 2022 and that the environmental process ended in September 2022, with inclusion in the Public Investment Programme still missing (article).

English Wikipedia gives a planned opening of 9 September 2027 and the Turkish page gives 2030, and both call the line planned (English page). A buyer counting on a metro should ask for the line, station and operating date in writing.

The developer gives the E-5 (D-100) at 3.5 km and 10 minutes. From the card pin, Istanbul Airport is 33 km away in a straight line and 53 km by road, and Sabiha Gökçen Airport is 56 km and 91 km away (road figures from OSRM, free-flow).

The developer lists Birinci Hospital at 1 km, Emin Yükseloğlu High School at 350 m and Bilim Vadisi Schools at 650 m, without addresses. Directory pages list an Emin Yükseloğlu Kız Anadolu İmam Hatip Lisesi (a girls’ Anadolu imam-hatip school) in Marmara Mahallesi; the Ministry of National Education list was not checked and no Bilim Vadisi school could be matched. OpenStreetMap shows a Birinci Göz Hastanesi, an eye hospital, 3.6 km from the pin, which does not match 1 km.

The Ministry-run Beylikdüzü State Hospital is mapped 4.7 km from the pin; the Istanbul Provincial Health Directorate confirms services. The Beykent University campus is 5.0 km away. Beylikdüzü Yaşam Vadisi, which the developer puts at 4.5 km, is a long linear park with sections 1.1 to 2.1 km from the pin, so its distance depends on the entrance. The municipality’s site is beylikduzu.istanbul.

Straight-line figures were calculated from coordinates (OpenStreetMap points and the card pin) with the haversine formula; road figures come from the public OSRM demo server. The pin is the card’s, not a surveyed parcel point, so every figure moves if the parcel lies elsewhere in Beylikdüzü.

Coast, noise and shared costs at Marina Residences Istanbul: what to check in a marina district

A scheme described as close to the sea and the marina raises four questions that a floor-plan page cannot answer: where the coastal rules apply, what noise reaches the facades, what the ground and water conditions are, and who pays for the shared facilities. The developer publishes no permit, report or management plan, so each point is a document to request.

The coast and the 100-metre strip

The Coastal Law 3621 (accepted 4 April 1990, Resmî Gazete 17 April 1990, no. 20495) defines a coastal strip (sahil şeridi) of at least 100 metres inland from the shore edge line (Article 4). The shore is open to everyone and no building may stand on it; yacht harbours are allowed there only by a zoning-plan decision (Article 6).

In the strip, the plan sets a building approach limit that can lie at most 50 metres from the shore edge line, and the ground between is for walking, resting and recreation (Article 5).

The developer says the scheme is a few kilometres from the Marmara Sea and 1.2 km from the marina, which points to a parcel outside a 100-metre strip, but the strip can be wider and no distance to the shore is given. The zoning plan sheet shows both. A sea view is also a position, not a right: it depends on the height limits of the plots seaward, set in the plan notes under the Zoning Law (Law 3194).

Noise from roads, the marina and the site itself

The Environmental Noise Control Regulation (Resmî Gazete 30 November 2022, no. 32029) covers noise from industry, transport, construction, music broadcasting and workplaces. It defines a strategic noise map as a province-wide map of the people and homes affected, an acoustic report as a document predicting levels against limits, and a main road as one carrying over three million vehicles a year. Businesses that broadcast music need a permit based on an acoustic report.

The E-5 (D-100) is 3.5 km away per the developer. The marina’s layout lists an amphitheatre, bars and a heliport. And the scheme’s own restaurants, cafés and shopping centre will bring delivery traffic and evening activity inside the site. No source gives measured levels at the plot, so which block faces which source is a matter for the site plan and, for a given facade, an acoustic report.

Ground, water and earthquake documents

The developer says a detailed ground survey was made and the foundation is reinforced, with C30/C35 concrete on rocky, clay and limestone ground. The matching document is the geotechnical report (zemin etüdü), including groundwater level. For hazard, the AFAD hazard map and the Building Earthquake Code (Resmî Gazete 18 March 2018, no. 30364 repeated) are the official references. Flood or stream exposure of the parcel is a question for the municipality and the water utility; the developer is silent on it.

Compulsory earthquake insurance (DASK) is computed from the gross area. At the unit cost of 12,039 TL per m² for reinforced concrete (policies from 1 October 2026), a 125 m² home has a computed sum insured of 1,504,875 TL and a premium of about 1,099 TL (risk group VII) to 4,244 TL (group I). The maximum sum insured is 2,552,268 TL, and a 225 m² home computes to 2,708,775 TL, so the cap would apply (calculated from the DASK tariff page, assuming gross plan areas).

Shared costs in a multi-block site

Under the Condominium Law 634, owners pay shared expenses in proportion to their land shares, except staff costs, which are divided equally unless the owners agree otherwise (Article 20). Late payment carries compensation of 5% a month, a tenant is jointly liable up to the rent owed, and an unpaid debt can be registered as a statutory mortgage on the unit (Articles 20 and 22). A manager is compulsory from eight independent sections (Article 34).

A scheme of several blocks on one site plan can be a “toplu yapı” (multi-building development) under Articles 66 to 74. Each block then has its own assembly, a representatives’ board runs the shared buildings and facilities, one management plan binds everyone, and facilities used by only some buildings are paid by those buildings (Article 72).

Law 7579 of 7 May 2026 lowered the vote needed to amend the plan in Article 70 from four-fifths to two-thirds of the units represented, and Article 37 now provides that the operating project (işletme projesi) is approved by the owners’ general assembly. A temporary management written into the plan may run until one year after completion and in any case ends ten years after the first building licence (Article 73).

The developer names pools, courts, a Turkish bath, restaurants and a shopping centre; agent pages add a sauna, a spa, a fitness room, an indoor pool, a generator system, underfloor heating with central heat meters and a three-storey car park for 350 vehicles. Against 340 to 360 homes and commercial units that is 0.97 to 1.03 spaces per unit (calculated from agent figures). No cost or ownership of these items is published.

Ordered checklist before signing

1. Obtain the block and parcel numbers and read the title record: owner, mortgages, annotations, floor easement or unit ownership.
2. Ask for the occupancy permit (yapı kullanma izin belgesi) and the date of the building licence, which fixes the VAT rule.
3. Read the zoning plan sheet and plan notes for the parcel and for the plots between the unit and the sea.
4. Ask whether any part of the site lies in the coastal strip or near a stream, and what the geotechnical report says about groundwater.
5. Request the acoustic assessment for the facade of the specific unit and the site plan showing the shopping centre and car-park entrances.
6. Read the management plan: land shares, common facilities, who owns and runs the retail centre, how facility costs are split.
7. Ask for the current service charge per square metre, last year’s accounts and the approved operating project.
8. Confirm parking and storage entitlement in the title record, not only in the sales contract, and compare the unit’s areas in the title record, plan and contract.

Buying in Türkiye in brief: the order of steps for a scheme with no published status

The order below starts from the point this scheme leaves open: whether the building is finished. Agents say ready; the developer says nothing. The answer decides which rules apply, so it comes before the price. The general framework is set out in the Turkey buying guide, and the payment side in the installments guide.

Applied to the card prices, the buyer’s 2% title fee is USD 5,200 on USD 260,000 (TRY 258,201 at 49.6540), USD 7,060 on USD 353,000 and USD 9,920 on USD 496,000, if the declared price equals the card price and is not below the municipal tax value. The statutory cost items are tabulated in the Turkey buying guide.

VAT depends on who sells. In a first sale by a developer, the rate turns on the licence date and the net area. If the plan areas are net, the blended rate would be 10.0% on 125 m², 11.4% on 175 m² and 13.3% on 225 m² (150 m² at 10%, the rest at 20%), which adds up to about USD 66,100 on the largest type if the card price excludes VAT.

A first delivery to a non-resident foreigner can be exempt under Article 13(1)(i) of the VAT Law when the price is brought in as foreign currency, with a three-year disposal condition; the invoice must state the treatment used.

Payment terms are not published by the developer. The Skyline page mentions 50% down and instalments over 24 months, which is an agent statement. If the project is finished, instalments are a private credit arrangement with the seller. If it is under construction, Article 44 of Law 6502 caps delivery at 48 months from the contract, and Article 45 allows withdrawal for 24 months against graduated compensation of up to 2%, 4%, 6% and 8% of the price by period. Every instalment needs its currency written in.

A buyer abroad can act through an attorney with an apostilled power of attorney and a translation, and does not need a residence permit to buy (TKGM guide). The deed, not the contract, passes ownership. All rates are as of 24 October 2026.

Risks, title and due diligence

The gaps in the public record define the risks. The developer publishes no status, so the first risk is a mismatch between what an agent calls ready and what the building has in law. Without an occupancy permit, Article 31 of the Zoning Law bars the building from mains electricity, water and sewerage, except for independent sections that obtained a permit.

The second risk is identity. Three neighbourhood labels and two plot sizes mean the parcel must be fixed from the title register before anything else is relied upon.

The third is price basis. Card prices are a broker feed in dollars, while a contract may be in lira, dollars or euros, and the lira lost 15.5% of its dollar value in the twelve months to 23 October 2026 (49.6540 against 41.9797 on 23 October 2025, CBRT). Every instalment needs its currency written into the contract.

The fourth is shared cost. A multi-block site with a shopping centre and many facilities has running costs that are published nowhere, and Law 634 makes unpaid charges a lien on the unit.

The fifth concerns claims that are not documents. Skyline marks the project as suitable for Turkish citizenship, but no published decision concerns this scheme: the regulation tests the valuation report and the individual unit. A green-area figure of 79% appears in the feature list of one agent listing and not on the developer’s pages.

The Skyline “construction size” of 12,000 m² cannot be gross floor area, since 300 homes of at least 120 m² need at least 36,000 m² (calculated from the smallest area on that page); the label may mean something else, such as a footprint.

Residence-permit rules also depend on the unit and the person: Article 31 of Law 6458 allows a short-term permit for owners, and since Law 7533 of 21 November 2024 the Ministry sets the nature and value of the property; a USD 200,000 floor for deeds from 16 October 2023 was reported by Cumhuriyet, and it is a press report of administrative practice, not a gazette text.

How Marina Residences Istanbul compares with the other Istanbul projects on this site

All eleven Istanbul listings are in the table. Where a listing carries a name other than the developer’s, the official project name is added. Prices are per our listing card, as of 24 October 2026, and come from a broker feed, not from developer price lists; status and delivery are given as the developers or official reports publish them.

Three differences bear on this project. It is the westernmost listing, on the Marmara coast; the other ten are in Beşiktaş, Eyüpsultan, Sarıyer (two), Şişli, Pendik, Ataşehir, Ümraniye, Üsküdar and Bahçelievler. Its entry price of USD 260,000 is the lowest of the dollar-priced entries, which run up to USD 684,000, a ratio of 2.6 (684,000 divided by 260,000).

Its card has three types, 2+1 to 4+1, against two on the Maslak Vision card and eleven on the Referans Beşiktaş card, although the developer’s text goes up to 5+2. As in most rows of the table, no status document is published, so the label “ready” here rests on agent pages.

See also the apartments for sale in Istanbul page for the wider inventory and the cities comparison for price levels by province. Short-term letting of a flat in a multi-unit building needs a permit and the unanimous decision of the owners under Law 7464, explained in the Airbnb-law guide, and the property tax calculator turns the annual rates into an estimate.

The developer: what the project pages say about Lionia Yapı and Partners

The only company description is the final section of the developer’s project story page. It states that Lionia Yapı and Partners was established in 2010 in Istanbul, to take part in the Turkish contracting sector, and that it has carried out projects in construction, precious metals, film and cinema, and tourism. It names a residential series under the Lionia brand: Lionia Yaşam Konakları, Lionia Life, Lionia Select, Lionia Live and Lionia Casa. It describes its work as medium and large residential projects and infrastructure projects.

The page gives no registered company name, trade-registry number, tax number, capital figure, project list with delivery dates, or address of other schemes. Skyline names “Lionia Yapı” as the construction company, which matches. The statement of ambition on the page is promotional and is not repeated here.

For a buyer, the verifiable record sits in public registers. MERSIS (mersis.ticaret.gov.tr) and the Trade Registry Gazette show the legal entity, its capital and its representatives, and the building licence names the licence holder and the building inspection firm.

The sales contract should name the same legal entity that holds the parcel title. Whether that entity is Lionia Yapı and Partners or a project company is not stated in any source read for this guide, and the seller named on the invoice is the party responsible for delivery and VAT.

Frequently asked questions

What is Marina Residences Istanbul and what is its official name?

Marina Residences Istanbul is the name under which this site lists the project. The developer’s own name for it is Yaşam Marina, by Lionia Yapı and Partners, in Beylikdüzü. The match rests on the plan sizes of 125, 175 and 225 m² and on entry prices that agree within 1% with a broker listing of Yaşam Marina. The developer’s pages are the source for facilities and plans; the listing card is the source for the dollar prices.

Where is Marina Residences Istanbul?

In Beylikdüzü, on the European side of Istanbul near the Sea of Marmara. Sources name three neighbourhoods: Marmara (developer’s office and port724), Adnan Kahveci (Skyline) and Kavaklı (the card pin). The developer publishes no block and parcel number, so the exact location has to be taken from the title record. Distances on this page use the card pin, 40.98189 N, 28.66131 E, and move if the parcel is elsewhere.

Is Marina Residences Istanbul finished, and when was it delivered?

The developer does not say. Skyline prints a delivery date of 20 November 2024 and port724 labels the project “Hemen Teslim”, meaning immediate delivery. Neither is an occupancy permit. A buyer should ask for the permit (yapı kullanma izin belgesi) and the title record of the exact unit. If there is no permit, the sale is likely to fall under the prepaid housing rules of Law 6502, including the 48-month delivery cap.

What unit types and sizes does Marina Residences Istanbul offer?

The developer’s floor-plan page shows a 2+1 of 125 m², two 3+1 plans of 165 and 175 m², and a 4+1 of 225 m². Its story page also states 5+2 homes and a range up to 375 m², without a plan. The listing card shows 125, 175 and 225 m². Skyline shows 120, 180 and 235 m². Whether areas are gross or net is not stated, so the definition should be fixed in the contract.

What do the prices of Marina Residences Istanbul mean?

The prices are the entry prices on the card on this site: USD 260,000 for the 2+1, USD 353,000 for the 3+1 and USD 496,000 for the 4+1, per our listing card, as of 24 October 2026. They come from a broker feed and are not developer prices. At USD 1 = TRY 49.6540 the entry price is TRY 12,910,040 for the 2+1. VAT, parking and fees may be additional, so the contract price has to be requested in writing.

Does buying here give Turkish citizenship or a residence permit?

No purchase gives either automatically. As of 24 October 2026 the citizenship regulation tests property worth at least USD 400,000, a unit with kat mülkiyeti or kat irtifakı, a three-year no-sale annotation, a valuation report and approval by the authorities. Only the 4+1 card entry (USD 496,000) is above the figure, and the valuation, not the price, decides. The residence permit for owners is a separate decision of the migration authority.

How far is the sea, and how far is the marina?

The developer says 1.2 km to West Istanbul Marina on one page and 5 minutes on another, and describes the scheme as close to the sea. From the card pin the marina is 2.1 km in a straight line and 3.1 km by road. The Marmara shore itself is not given a distance by the developer. Under Law 3621 the coastal strip is at least 100 metres wide, and its extent for the parcel is shown on the zoning plan.

Is there a metro near the project?

The developer’s concept page mentions a “2023 METRO” 15 minutes away on foot without a line name. The only metro project found for Beylikdüzü is the planned M20 Sefaköy-Beylikdüzü-TÜYAP line, with about 18.5 km and 10 stations; sources read in October 2026 describe it as planned, with opening years that differ. The metrobus, a bus rapid transit line, is the high-capacity service that runs today, with a stop about 2.9 km from the card pin in a straight line.

What does it cost to buy a flat, apart from the price?

The standard items are the buyer’s 2% share of the title deed fee, a DASK earthquake policy, a valuation report and, for a first sale by a developer, VAT of 10% on the first 150 m² net and 20% above for licences after 1 April 2022. For a 125 m² home, the DASK premium runs from about 1,099 TL to 4,244 TL depending on risk group (calculated from the DASK tariff of 1 October 2026). Service charges come on top.

What service charges apply in a multi-block site?

They depend on the management plan, which the developer has not published. Under Article 20 of Law 634, shared expenses follow land shares, staff costs are equal, and late payment costs 5% a month. A multi-building site can have block assemblies and a representatives’ board under Articles 66 to 74. The pools, courts, Turkish bath, restaurants and shopping centre named for the scheme make the operating budget a first question for any buyer.
