The two-room apartments have an area of approximately 50m² each. The apartments are arranged as so-called maisonettes, with the living room, the kitchen and the balcony on the street side facing south. The bedroom and bathroom are on the garden side of the complex, facing north. The apartments are delivered complete, including a PVC floor, finished walls and ceilings and lighting. The kitchen has built-in appliances and a grey composite worktop and light grey kitchen cabinets, a combination of shades that creates a pleasant and peaceful atmosphere. In addition, the apartment has a bathroom with a wash-basin and a spacious shower and a separate toilet. The apartments are heated by means of floor heating that is connected to the heat pumps of the thermal storage system. The solar panels installed on the roof provide electricity for the central facilities, among other things.

All residents have their own outdoor space facing south, and they are also allowed to use the communal roof terrace of the neighbouring De Karel 1.0 complex (transformation of the urban district council office building).

The facade is made up of vertical, slender stone strips combined with large windows and dark aluminium frames. By using the same materials as the adjacent buildings and placing them in a different structure, De Karel 2.0 fits perfectly between the adjacent buildings, but at the same time has its own clear signature.
