The architects started their architectural task by researching the maximum number and size of possible new openings in the façade. All in close contact with the monuments' committee of the municipality. After securing the right to open-up the old window openings in the facade and add new windows and doors, the possibility to create a well-lit space was conceived. To further enhance this, Firm architects decided to disconnect the new interior from the old walls. This appearance of the design is somewhat subtracted from the original shell, the old brick walls has a dual purpose; it creates architectural contrast and it ensures the minimal north-facing daylight to flow in across both levels as the architects bridged the half meter between the interior and the outer wall with a glass floor over the full width of the facade. Furthermore, they added mirrors on the walls on both levels to enhance this effect.

In the interior, the design principle of subtracting the new from the old creates an enriched dialogue between the original building and its novice function. This is strengthened by technical material usage in the new interior such as aluminum wall paneling and a stainless steel kitchen. The wood paneling forms a volume embracing the large central vide and ensuring a perfect acoustic for an office.
