What Is an Earthquake-Resistant Home? How Is Real Safety Recognised?
The search for an earthquake-resistant home in Türkiye is no longer a preference but a necessity. Yet understanding whether a home is truly safe usually requires much more than the few technical phrases found in listings. Being newly built, or the phrase 'compliant with the earthquake regulation', is not enough on its own. What really matters is the criteria and the safety margin with which the structure was designed.
An earthquake-resistant home is a structure that moves in a controlled way during an earthquake, aims to remain standing without collapsing even if its load-bearing system is damaged, and prioritises life safety. At the foundation of this approach lies the Turkish Building Earthquake Regulation, which defines how buildings are exposed to earthquake loads, how those loads are calculated, and the performance targets buildings must be designed for. One of the most critical concepts in the regulation, however, is often overlooked: the building importance factor.
The building importance factor shows the safety margin applied in a structure's seismic calculations. In standard residential projects this value is generally taken as 1.0, while some buildings are designed with a factor of 1.5 — meaning the building is designed for roughly 50% higher earthquake effects than a normal home. The load-bearing system is built stronger, safety factors are increased, and post-earthquake damage limits are kept far lower. This approach is generally applied to hospitals and critical public buildings; choosing it for a residential project reflects a top-tier understanding of safety.
Fatih Tolga Çehreli, Chairman of the Board of Art Royal, summarises the safe-building approach at Royal Silva: the building importance factor is one of the most important criteria showing the safety margin with which a structure is treated against earthquakes. A 1.5 factor means the building is designed taking into account far higher earthquake effects than a standard home. At Royal Silva, the goal was for people to feel safe in their homes not only during an earthquake but afterwards as well — which is why the project was handled from the outset with a high importance factor and a strong load-bearing system.
In an earthquake-resistant home, not only the calculation method but also material quality is decisive. Here, high-strength concretes such as C40 stand out. Offering high compressive strength, this concrete class increases load-bearing performance and helps the structure preserve its structural resistance for many years. Especially in buildings designed with a 1.5 building importance factor, the use of high-strength concrete is not a preference but a natural consequence of the engineering. At Royal Silva, the earthquake-resistant approach was the project's founding principle, not an added feature. The structural system designed on a 1.5 building importance factor and the strong load-bearing structure built with C40 concrete target the upper limits of the earthquake regulation, not its minimums. Because real safety means feeling at peace in your home not only during an earthquake, but every day. And that shows the real investment is made not in a house, but in a life.
