our work

First step: The ground floor is converted into a two-story component of the multi-purpose building for the tenant. Demolition and expansion work are necessary for this. Subsequently - on approximately 1400 square meters - partition walls are created within the rental property as well as sanitary areas including tea kitchens.

The new color and material concept creates a bright and friendly impression. Coordinated shades of gray create a modern, calm atmosphere.

Second step: The currently vacant 1st floor will be converted for a future tenant.
