The Micro Dwellings can expand and grow together with other systems into small communities. They can be built onto rooftops of existing buildings or be suspended from a bridge or a wall. The modules can be mounted on wheels or be connected to form floating constructions.

The compressed version of a MD contains very simple equipment for living. However, three modules can be combined to allow for separating functions:
- Eat: kitchen area, including micro-greenhouse. Floating MD can have their own fish farms, chicken farms and floating gardens attached outdoors.
- Shit: the toilet and shower. All tanks can be mounted on the outside to save space. Grey water can be led to the micro-greenhouse and purified by the plants. A micro-desalination plant can be installed for deriving drinking water from sea water. The toilet can be a compost toilet that uses no water.
- Sleep: movable furniture in the form of polyethylene modules serve as sofas, beds, and tables according to needs. Bed linen, duvets etc. can be kept in a net during daytime. Flexible screens can divide the space to create privacy if wanted.

In addition, smaller modules of various shapes can be attached, if there is a need for extra rooms, storage, etc. An energy unit could be hooked on to the MD, consisting of micro-windmills, solar panels and heat systems, heat pumps, etc.
