Cross-trade craftsmanship
Our roots lie in the stucco business. In order to further improve construction quality, speed, reliability and even execution standards, we had to evolve. We now offer many other services. With our own craftsmen — and experienced cooperation partners.

For greater reliability, speed and efficiency!
One of the biggest challenges in construction is coordinating the trades so that a construction schedule can be met. We therefore combine all trades with our own staff, from shell construction to plastering and stucco work, drywall to painting by painters (masters). And we prefer to recommend experienced partners in trades that we do not carry out ourselves. Here, colleagues know each other — and not just the bosses. This makes it more fun to shape your vision!
Shell construction
With us, you can rely on experienced teams of construction management and experienced masons who know that their work lays the foundation for all other trades. We stand for robust construction and structural work with precision and quality.
Plaster and stucco
Our recommendation for saving energy: With our stucco and cleaning department, we carry out work with care, craftsmanship and great speed. Climate protection has no time to waste. Feel free to ask us about our composite thermal insulation systems (WDVS)!
Drywall
We can make walls stand even without concrete. Our drywall services are an ideal addition to quickly achieve the goal of interior design or to give existing rooms a new structure.
Painting & varnishing work
Our painters also know how the works of previous trades work. Important when you need to support each other so as not to waste time. It is therefore best to think of the extension down to the last brush stroke and not cause interface problems through manual execution. Cleaning and painting work in particular should be thought and done together.
Quick and reliable from a single source: That is HAHN quality.

Sötern primary school
The Sötern primary school in the national park community of Nohfelden was converted and expanded in accordance with the highest DGNB sustainability standards. We were there with our construction team and virtually laid the foundation.
Our services: floor replacement with 524 m³, floor plate with 681 m² (C25/30), WU floor plate with 100 m² (C25/30), concrete wall with 150 m² prefabricated elements (C25/30), a reinforced concrete ceiling with 103 m² with 25 cm thickness (C25/30) and sand-lime brick built on 50 m².


Trier Süd apartment building
Not far from the city center of Trier, there are two real eye-catchers with these two apartment buildings. Even though the buildings have been used intensively for several years, the 2500 m² of exterior plaster in distinctive broom strokes and various mottos in the corridors, sometimes with photo wallpaper, show the high quality of our finishing work — both outside and inside.


Odernheim Fire Department
This building is banging! With the signal red paint on 1500 m² of exterior plaster, we were once again able to make our contribution to safety in the region. The profitability of our services is not only characterized by longevity, but public tenders also show that we do not have to shy away from comparison.


Realschule plus Thalfang
Quality and quantity: With this project in Thalfang, we were nominated for the Brillux Design Award in 2019. Among 700 submissions, we took 2nd place in the interior concept work category! With 4500 m² of painting of lime cement plaster walls, 2600 m² of expanded metal had to be applied, 2800 m² of wall surfaces plastered and filled, 3800 m² of fleece wallpapered, 2800 m² of drywall ceilings and 2500 m² of staircases painted. The crowd alone shows that not many can do that. We do!
