Our experience

From the beginnings to the present day: We invite you to follow our company history on a journey through time…


Foundation and early years

On 2nd November, Ralf Rudolph, who to this day is the chairman of the company’s supervisory board, founds Anton Schmittlein Construction GmbH. The company is registered in the Charlottenburg register of companies. During the early years, at the time of the oil crisis, the company’s building activity is concentrated in countries outside of Germany.


Discovering a love of old buildings

We modernise our first old Berlin apartment block at Hildegardstraße 14 / Schrammstraße 4 in Wilmersdorf. Over the following decades, we renovate and refurbish over 100 further old buildings in Berlin.


Well managed

The company expands its range of services, starting to work in property management.


Clever software

The company introduces Modhaus, a multi-functional management support software designed in-house that can be adapted to our needs and requirements with complete flexibility. It helps to optimise communication processes and to this day is continually enhanced as needed.


Growth needs space

The extension of the company’s own building at Burggrafenstraße 3 – just around the corner from KaDeWe – is finished, offering our growing workforce additional office space.


Breaking new ground

We carry out our first modernisation project in Berlin-Prenzlauer Berg, at Kanzowstraße 3/3A.


Reaching the big 100!

A milestone in old building renovation: Hufelandstraße 17 in Prenzlauer Berg becomes the company’s 100th project.


30 years!

In November, the entire team celebrates the company’s 30th anniversary all day long, including a sailing trip and mulled wine.



Beside the Weißer See lake on the plot at Große Seestraße 4 the company completes an extraordinary residential property project: a combination of old building modernisation and a new building, including an underground garage and a wonderful communal garden with access to the lakeside park.


40 years!

Kids, how time flies! Exactly on the day 40 years after company founding the anniversary was celebrated. At a hearty breakfast on the roof terrace of the Reichstag, there was initially a cozy refreshment. This was followed by a short tour of the Reichstag dome before Köppchen was in demand. Divided into different groups, it was necessary to puzzle out of the locked rooms of the Escape Rooms. Fortunately, everyone is free again, so that the evening ended with food, music and dancing in the Loretta am Wannsee sociable.
