Resident experience

These are reported experiences, not independent building inspections, and may not represent all residents or properties.

Risks & source coverage

  • LEGAL 2014–2021 (reported July 22, 2021) In reporting on the KÖY project, a court challenge by the TMMOB Chamber of Urban Planners was described as having led the Council of State to suspend execution of the zoning plans in 2014; a further suspension concerning transfer of the land was reported in 2016, while the project continued and Siyahkalem withdrew from the project in January 2020, after which Emlak Konut contracted another builder for the remaining works. The report presents these as court and project-status developments, not as a final finding of wrongdoing by Siyahkalem.
  • PROJECT CANCELLED Reported January 10, 2020 Emlak Konut’s KAP disclosure, as reported, stated that six parcels in the Emlak Konut–Siyah Kalem KÖY revenue-sharing project were removed from the contract through partial liquidation, with the work continuing only on parcel 1791/2; this was a partial project scope cancellation, not a statement that the entire project was abandoned.
  • RISK Reported February 2026 A buyer alleged that, after signing a reservation agreement through an estate agent and preparing payment, Siyah Kalem withdrew from the agreed sale of an İhlamurkuyu apartment; the complainant said the alleged loss was approximately TL600,000 and sought completion of the sale or compensation. The page records an individual complaint and does not establish that the allegations were adjudicated.

Click a row in the chart to open a project, or a table row below to see its sources. The chart runs wider than the page where the record spans many years — scroll it sideways to follow a project to its handover. Every date we have is drawn. A hollow marker is only a launch year, not a date anyone published. No dates published means we looked and found none; dates not yet checked means we have not looked yet. Handing over is not finished — rows say which. A delay is shown when one source gives the promised date and another gives the real one, however rough: "2019" still counts, and the row shows how wide that is. Projects missing one of the two dates, or with sources that disagree, are left out of the figures. 4 turned out to be about something else — a phase, a neighbour, the wider masterplan — and are marked off-subject.

The largest published aggregate located is 4.0/5 from 192 reviews, giving a 7.0/10 anchor under the requested conversion curve. The 3.76/5, 62-review aggregate is directionally similar, but the written feedback adds repeated concerns about management, security, pool upkeep, signage and common-area maintenance; the resulting resident-experience score is therefore 6.6/10. Structure is lower-confidence because the physical complaints are reviewer reports rather than an engineering assessment.

+ Modern-looking homes+ Good design+ Open and closed pools+ Fitness and sports facilities
− Reported low-quality finishes− Reported ceiling collapse in a neighbouring home− Pool water-quality complaints− Broken apartment doors and cameras− Inadequate common-area cleaning
+ Natural setting+ Clean air+ Quiet lifestyle+ Good location+ Modern residential environment
− Unresponsive management− Security concerns at west gate− Poor wayfinding− Pool upkeep complaints− Construction disruption reported in the wider project

The published feedback is not uniformly positive on the physical asset. One reviewer wrote that “Evler cok kalitesiz” and reported a neighbour with a collapsed ceiling, while another reported broken apartment doors and cameras and poor cleaning for 1.5 years; these are resident reports, not independently verified engineering findings.

Residents and visitors repeatedly praise the natural setting: one review calls it a place with “Temiz havası ve bol oksijeni,” and another describes it as “sessiz ve sakin bir doğal yaşam alanı.” The operational feedback is substantially more critical: reviewers allege that management responds slowly or not at all, report “Şimdiye kadarki en kötü güvenlik!” near the west gate, and describe recurring pool, cleaning and signage problems.

Only buildings that have reached handover are rated. 0 of 1 project carry no rating: a building still under construction is never asked about, one that has just been handed over may not have been reached yet, and the rest were asked about and no published resident commentary was found. Structure is fixed at handover and stays the developer's; management and living belongs to whoever runs the building now. The overall verdict weights both rather than averaging them. None of this is checked: a rating is what people published about a building, aggregated — it is not evidence, it cannot move a delay figure, and it is not part of the delivery record above.

Projects

Assessment coverage

Completed projects: 2016-10-15 through 2026-10-15. Initial research is capped at 10 completed projects and a separate delivery-risk search capped at 7 findings. Risk findings are not project assessment counts. Absence is not proof of a complete portfolio or no failures. Month-level dates overlapping a boundary are excluded from figures.

0 undated completions and 0 boundary-uncertain completions are retained but excluded from figures.

Stalled, cancelled & overdue projects

0 evidenced cases
The capped delivery-risk search ran; no project-level exception cases are recorded here. Risk findings are listed under Risks and are separate from assessed projects. This does not establish that the developer has no delivery failures.

LEGAL 2014–2021 (reported July 22, 2021)
In reporting on the KÖY project, a court challenge by the TMMOB Chamber of Urban Planners was described as having led the Council of State to suspend execution of the zoning plans in 2014; a further suspension concerning transfer of the land was reported in 2016, while the project continued and Siyahkalem withdrew from the project in January 2020, after which Emlak Konut contracted another builder for the remaining works. The report presents these as court and project-status developments, not as a final finding of wrongdoing by Siyahkalem.
PROJECT CANCELLED Reported January 10, 2020
Emlak Konut’s KAP disclosure, as reported, stated that six parcels in the Emlak Konut–Siyah Kalem KÖY revenue-sharing project were removed from the contract through partial liquidation, with the work continuing only on parcel 1791/2; this was a partial project scope cancellation, not a statement that the entire project was abandoned.
RISK Reported February 2026
A buyer alleged that, after signing a reservation agreement through an estate agent and preparing payment, Siyah Kalem withdrew from the agreed sale of an İhlamurkuyu apartment; the complainant said the alleged loss was approximately TL600,000 and sought completion of the sale or compensation. The page records an individual complaint and does not establish that the allegations were adjudicated.
PROJECT CANCELLED 5 Dec 2019 (reported publication date; Emlak Konut/KAP status announcement); replacement contract signed 23 Dec 2019 and site delivered 24 Dec 2019.
Semt Bahçekent (İstanbul Esenyurt/Hoşdere 6. Etap) was formally described by Emlak Konut GYO as having been liquidated, with the remaining completion works to be re-tendered; Siyahkalem was subsequently appointed only for the replacement/ikmal construction contract, so the event does not by itself establish parent-company liability for the original failure.
DELIVERY DELAY 10 Jan 2020 (partial-liquidation report); Siyahkalem records completion and handover in 2020.
KÖY Zekeriyaköy’s second-stage parcels were removed from the Emlak Konut–Siyahkalem contract through partial liquidation in January 2020, and Emlak Konut later contracted Yıldızlar İnşaat for the remaining works; Siyahkalem’s own current project page says the project was ultimately completed and handed over in 2020, so this is resolved delay/restructuring history rather than a current failure.
