Aparthotel Eschborn

The Aparthotel Eschborn continues the long-standing partnership between the Karlsruhe Directorate for Turnkey Construction and the Troisdorf-based P+B Group. This is already the fifth joint project. In addition to the Subdivision Karlsruhe, the SFB division, the Central Directorate was also involved in the construction of the shell of the building. The centrally located aparthotel was built in the Eschborn Süd industrial estate, has ideal transport links and is in the immediate vicinity of the Frankfurt metropolis. With a total living space of 4,387 square meters and 179 rooms, Campo Novo Business offers furnished apartments for individual needs.

The project comprises 179 apartments with 18 barrier-free and 2 fully barrier-free apartments spread over six upper floors and the first floor. The fully accessible apartments offer more space and meet more specific and higher requirements for people who are dependent on a wheelchair, while the first floor houses a modern lobby, reception, a breakfast kitchen and a wash lounge in addition to the apartments. The building also has a partial basement. There is a bicycle room with space for 70 bicycles, which can be accessed directly from the street via a bicycle elevator. The garbage, technical and storage rooms are also located in the basement.

Sustainable construction and technology

The building was constructed to the KfW 40 standard. To achieve this standard, a photovoltaic system and an air-to-water heat pump were installed on the roof. A combined heat and power unit and a gas condensing boiler are used to cover peak loads. The thermal envelope is fully insulated. The following were used on the façade:

• an external thermal insulation composite system (ETICS) with plaster and
• a rear-ventilated façade with Alucobond panels.

The roof was implemented as a retention roof and insulated with pressure-resistant EPS panels and sealed with bitumen. The construction period was 24 months, from August 2022 to August 2024.

Building procedure

The basement was largely constructed using in-situ concrete, the upper floors almost exclusively with semi-precast elements and filigree slabs. All balconies as well as the façade wall panels are fully prefabricated and thermally decoupled from the building. Each balcony is equipped with a powder-coated balcony cabinet to ensure privacy between the apartments. In order to keep the degree of prefabrication as high as possible and to shorten the construction time, prefabricated wet cells and prefabricated shafts were already installed in the shell, which shortened the construction time by a further few weeks and reduced the amount of waste.

Efficient interior fit-out with LEAN

The LEAN principle was used during the interior fit-out, as this allowed the construction project to be planned and implemented more efficiently. The Campo Novo Business aparthotel was ideally suited to LEAN scheduling due to the identical structure of the upper floors, with two LEAN scheduling areas defined per floor, each with 13 and 14 apartments respectively. This structure made it possible for all the finishing trades to work in an orderly, systematic manner with minimal downtime and low resource consumption, enabling the project to be successfully completed after two years of construction. The first guests were able to move in immediately after the building was accepted in August and the Aparthotel Eschborn has enjoyed a high occupancy rate since its opening.

Sustainable construction site "Campo Novo Business"

With this project, Ed. Züblin AG is pursuing several sustainability goals: resource-conserving construction site organization, minimization of emissions, responsibility for the health and well-being of those building, care for good neighborly relations and high-quality construction. The company was the first to be recognized for this by the German Sustainable Building Council (DGNB).

The project is aiming for DGNB "Sustainable Building Site" certification from the German Sustainable Building Council.

Certified by the German Sustainable Building Council (DGNB)

Ed. Züblin AG is pursuing several goals with this project: A sustainable construction site organisation, the conservation of resources as well as the minimisation of emissions, responsibility for the health and well-being of the builders, the cultivation of good neighbourliness and, of course, high-quality construction. For this, Ed. Züblin AG was the first company to be recognised by the German Sustainable Building Council (DGNB).
