From the outset, EGG 104 has been characterised by a strong focus on sustainability, which is reflected in all aspects of the planning. The priority is on an energy-efficient design that emphasises the environmental aspect. The building is being planned according to the highest sustainability standards and is aiming for DGNB Gold certification. There will also be a PV system and a green roof terrace with recreational areas. The combination of the use of geothermal energy for sustainable operation together with a generous photovoltaic system and the improvement of the microclimate through intensive and extensive green roofs guarantee the highest sustainability standards.

Retail space is planned for the ground floor of the new building. There is an existing building on the site which could be used as storage/light industrial/workshop space on the ground floor. The existing building will also have a goods lift to the basement, which will provide access to the storage areas. The office areas will be equipped to a high standard, including heating/cooling sails, external electric sun protection and much more. In the basement, the tenant has 45 duplex parking spaces (incl. 2 disabled parking spaces), some with electric charging points, and storage areas. Outside, there are 48 partially covered bicycle parking spaces with charging facilities.
