We with any building.
Except castles in the air.

Are you starting a classic new building project in a luxury apartment complex in Berlin? Or a complex conversion for a city hotel in Hamburg? Or refurbishing a medical center in Leipzig to meet the latest fire prevention standards? Or planning a test laboratory for future-oriented room air technologies in Novosibirsk?

Whatever it is that you are planning, we will be happy to assist you in making it a success. Personal, integral, sustainable, and with a high level of expertise. Throughout all the life cycle phases of your property and beyond.

30 years of decon.
360° building expertise.

More than three decades of expertise in the construction and property sectors. Clearly proven in around 800 successful projects from all areas of daily life.

70 passionately committed pioneers, action-takers and future planners, in four locations in Germany, have the bigger picture in sight: your project and the profitability of your property. That’s decon: your all-round partner for sustainable, successful buildings.

Or to put it another way: a modern engineering company for facility management-oriented, technical overall planning and a partner-run, family-owned company that is highly respected throughout Germany. That means you don’t just have the peace of mind of relying now on our many years of interdisciplinary experience, but of continuing to do so in 30 years’ time. Guaranteed. Whether you want us to implement your construction project or manage your property.

From A for aggregate.
To Z for zoning.

We don’t have the power to stop climate change - or the increase in the cost of energy and raw materials. However, what we can and strive to do is to maintain the competitiveness and value of your property in the future - and even to increase it. By keeping later building operation costs in check. We use tried and tested, certified decon success mechanisms, which we put into practice at the right time and in the right place, for your particular needs: from technical services to property management. From our combined experience and expertise to interdisciplinary experts and innovative tools.

And because every construction project is not just unique, but also challenging, we always take every tiny detail into account during the planning stage, and are always on hand to help during every service phase. Personal, integral, and with a high level of expertise. We support you in developing, preparing and implementing your project, or in managing your property.
