The antithesis of trend is tradition. Without tradition’s deep roots there can be no growth – and no beauty, because beauty always draws from experience, and therefore history.

Architecture is a form of constructed history. However, it is usually regarded only from the creator’s vantage point and rarely illuminated from other perspectives. But it is often the developer
and client, the “director” of the building process, “who must have an overview equally of the score, orchestra and audience,” as renowned architect Paul Kahlfeldt describes it. “And the Schmitz family firm understands itself as the director; they approach each project as if for themselves – just in multiples.”

The firm’s history began in 1864 when Peter Heinrich Schmitz founded a construction company in Grefrath am Niederrhein, establishing a family tradition of craftsmanship. After
erecting churches, cloisters and factories in the region, the Schmitz company built their first villa in 1896 on commission
from a textile manufacturer, marking the start of business in the premium residential segment. The third-born son, Heinrich Schmitz, founded the office in Kempen some ten years later, which he continued to lead as Heinrich Schmitz KG after 1919.

As the market became increasingly saturated in the 1970s, however, Ralf Schmitz – the firm’s fourth-generation son – concentrated on the development of particularly high-quality residential estates and founded his own company in Kempen in 1977 at the age of just 24. The firm established itself in no time with its refined freehold flats in Kempen, Krefeld and Düsseldorf.

The company made its first foray into Berlin in 2004; two refined city villas in the well-heeled district of Grunewald were markers of the things to come. Simultaneously a diverse group of new, striking sites were planned and realised in Düsseldorf.

Finding suitable real estate in good and excellent residential areas in these urban hubs has become increasingly complex. The Berlin branch of the Schmitz company has since become synonymous with the development of high-quality real estate, thanks in part to its intensive collaboration with numerous renowned architects, as has been the practice in Düsseldorf.

The Schmitz-Wohnungsbaugesellschaft was reconstituted as Ralf Schmitz GmbH. The firm remains entirely family-run and is owned 100 per cent by the family. In 2013, the Hamburg office’s first real estate project was completed in the upscale Othmarschen district. On the occasion of its 150th anniversary, the monograph Architektur und Handwerk was published by Jovis, providing a multifaceted documentation of the classical and elegant buildings built by the Schmitz family.

In late 2016, the international press cheered the completion of the prestigious Eisenzahn 1 near Berlin’s Kurfürstendamm – the first and exclusive collaboration between Italian luxury brand Bottega Veneta and a German development group.

Various new projects are currently under construction or in planning, thus proving that founder Peter Heinrich Schmitz’s guiding mandate has withstood the test of 150 years’ time: “Only value will endure.”
