BUYER SEGMENT · HERITAGE RESTORATION
Restoration stone supply demands a different discipline than standard new-build: historic stone matching, batch vein consistency, traditional finishes (aged, patina, tumbled, hand-tooled) and UNESCO / conservation jury acceptance. Sipahi Marble plans batches from Turkey's leading heritage-stone regions — Amasya, Marmara Island, Elazığ, Bilecik Söğüt, Diyarbakır Karacadağ — against restoration spec.
RESTORATION PROJECT NEEDS
In restoration the replacement stone must share the character of the original. Color, vein texture, grain size and surface character are evaluated against photos or original samples. Stone series from Turkey's regions offer matches for Ottoman, Seljuk and Roman-period buildings.
Even if the restoration batch does not come from the same original block, vein direction, vein density and color homogeneity must be consistent. Single-batch production + per-producer-batch photo approval is critical for restoration spec. Sipahi runs this step by default before order.
Restoration surface character differs from the modern high-reflectance cut stone: aged, patina, tumbled or hand-tooled finishes are typically required. This work runs at a specialist partner workshop line — it is not standard CNC production.
For UNESCO World Heritage candidate and protected building restorations (Amasya historic city, Konya Mevlana surrounds, Diyarbakır city walls, İstanbul historic peninsula), stone selection and intervention method must align with the ICOMOS Venice Charter and national heritage legislation. The supplier must offer spec support against this framework.
Restoration jury reviews require documentation of the new stone's origin, mineralogical analysis and comparison against archive photos. The supplier prepares this document chain as a standard submittal — production region, geological period, chemical-mineralogical analysis and archive visual comparison.
Facade molding profiles, column capitals and door/window surround details cannot be produced by modern machine cutting alone — they are hand-crafted by traditional stone masons using chisel, tool and sand. These details are planned per order at a partner workshop with heritage stonework capability.
SIPAHI SERVICE PACKAGE
Amasya beige marble is a widely-used stone series in Anatolian Ottoman architecture — matched by vein direction and color homogeneity in mosque, madrasah and konak restorations. Sipahi plans batches with Amasya regional producers to meet restoration spec; photo and sample piece comparison drives the approval loop.
Marmara Island white marble has been known since antiquity as Prokonnesos — used in Byzantine, Roman and Ottoman buildings for columns, plinths, door moldings and floor slabs. For antique building matching Sipahi sources from the island; vein character and mineralogical analysis reports secure UNESCO / conservation jury acceptance.
Elazığ cherry marble is a burgundy-cherry veined stone — used in historic hamam floors, mosque courtyards and konak paving as a luxury series. Vein direction consistency in restoration is critical; Sipahi's regional supply network runs to that spec discipline.
The Bilecik Söğüt corridor beige marble has been accepted from the Seljuk era through early Ottoman construction as a warm-tone Anatolian stone. Today it is still matched in Söğüt, Bilecik and Bursa heritage restoration. Sipahi's ~110 km logistics advantage to the Adapazarı Tekeler center delivers fast sampling and fast supply.
Diyarbakır Karacadağ basalt is the original stone of the UNESCO World Heritage Diyarbakır City Walls and inner historic buildings. Wall restoration demands aged finish + vein consistency matching the historic appearance. Sipahi plans batches with Karacadağ producers to the restoration spec.
In restoration, aged (tumbled, sandblasted), patina (chemical + time-aging) and hand-tooled (chisel and tool marks) surfaces replace modern polished/honed finishes. This work is planned at a partner workshop with traditional stone-mason capability. Sipahi remains the single coordinator and spec compliance tracker.
SIPAHI 4-STEP MODEL
TURKISH UNESCO CITIES
Turkey's UNESCO World Heritage inscribed (Diyarbakır Walls, İstanbul historic peninsula) and candidate cities (Amasya, Konya, Bursa) all host active heritage restoration. These projects apply stone matching + traditional finish standards; the spec is decided under ICOMOS Venice Charter principles and national heritage legislation.
Sipahi's supply network is set up to serve these restoration fields concurrently: Amasya beige marble (Ottoman historic city), Konya beige marble (Mevlana + Seljuk heritage), Diyarbakır Karacadağ basalt (city walls restoration), Marmara Island white marble (ancient Prokonnesos — İstanbul historic peninsula), Bilecik Söğüt beige marble (Seljuk + early Ottoman), Elazığ cherry marble (classical luxury historic hamam and konak).
Public flagship references: Ada Hayat (Adapazarı Municipality urban regeneration), Baltürk Hotel, Özel Medar Hospital and Sipahi Business Center.
FREQUENTLY ASKED
The architect / conservation specialist shares a clear photo of the existing stone (showing color, veining, surface character), a dimensional sample and if possible a physical piece. Sipahi identifies the closest character from Turkey's production regions; a first-round comparison of 2-3 short-panel alternatives is prepared. On decision, single-batch production + photo approval steps run against the restoration spec.
A typical jury submittal covers: origin certificate (production region + geological period), mineralogical analysis (petrographic examination, chemical content, XRD/XRF), comparison document against archive photos, sample piece, and intervention method report (ICOMOS Venice Charter alignment, reversibility principle). Sipahi prepares this package as standard submittal; the architect / conservation specialist takes it into the jury presentation.
Aged: tumbled (edge-corner rounding in a tumbling drum), sandblasted (surface texturing under abrasive blast), acid-washed (chemical surface etching). Patina: oxide-based chemical treatment mixed with natural aging simulation. Hand-tooled: traditional stone masons reproduce archive-photo tool marks with chisel, point and abrasive. All three run at a partner workshop's specialist line — not standard CNC, but a per-order craft process.
Turkey UNESCO World Heritage listed + candidate cities: İstanbul (historic peninsula — inscribed), Diyarbakır (city walls + Hevsel Gardens — inscribed), Amasya (Ottoman historic city — candidate), Konya (Mevlana + Seljuk heritage — candidate), Bursa (early Ottoman urban fabric — candidate). Historic building restorations in these cities apply stone matching + traditional finish standards. Sipahi's supply network plans batches from Amasya, Diyarbakır Karacadağ, Konya beige and Marmara Island (matching İstanbul historic peninsula) regions to restoration spec.
Yes. Coordinated per order at a partner workshop with traditional stone-mason capability. Facade moldings (egg-and-dart, meander, palmette), column capitals (Ionic, Doric, Corinthian, Ottoman mukarnas) and door/window surround details are produced with archive photo or original sample piece as reference. The process is craft-heavy — lead time 4-12 weeks depending on detail complexity.
Small quantities (a few m², one column capital, a meter of molding) are accepted — restoration spec discipline sits above standard supply, so minimums are not strict. However, specialist craft work + per-batch producer selection creates fixed overhead; unit pricing on small orders may be higher than standard supply. A written pre-quote lays out clear pricing tiers based on project detail.
Balıkesir Marmara Island (ancient name Prokonnesos) white marble was used widely in Byzantine, Roman and Ottoman buildings. Production is still active on the island — Sipahi plans batches with regional producers to the restoration spec. Vein character (fine, medium or thick), color tone and mineralogical alignment are matched to the antique original. For UNESCO / conservation jury acceptance the mineralogical analysis report is added to the standard submittal.
The restoration spec cycle runs longer than standard supply — existing stone matching + photo approval + mineralogical analysis + jury acceptance total 4-8 weeks. Producer batch reservation + traditional finish + hand-tooled detail add another 4-12 weeks. Total order-opening-to-site cycle is typically 8-20 weeks. Sipahi shares a detailed schedule at kickoff; critical-path batch reservations open early.
Share a photo, dimensional sample and if possible a piece of the existing historic stone. Sipahi prepares 2-3 short-panel alternatives; the mineralogical analysis + jury submittal package runs against conservation spec.
