Case Study #1 Hamburg

 

How might we imagine a modern house that is adapted to the lives of its inhabitants, while remaining cost-effective and feasible as a whole? The architects Fusi & Ammann show us how it can be done with their design “Case Study #1 Hamburg”.


Case Study #1 Hamburg is versatile and adaptable in a number of different respects. To begin with, the prefabricated house can be erected in a wide variety of different locations. It can be built as a free-standing apartment block on open land, inserted into an empty site in the inner city, or integrated into an existing terrace or perimeter development.

Another distinctive feature of Case Study #1 Hamburg is its modular and versatile structure. The basic principle behind this is quite simple: it is composed of 45 square metre modules with square ground plans, which can be joined together or stacked vertically or horizontally. This results in layouts that allow the units to be partitioned and split across floors according to individual taste. The modules are centred on a shaft which contains the building’s technical installations and acts as a static anchor point. The modules are made up of prefabricated elements such as pre-stressed concrete ceilings, wood composite structures, and precast concrete walls with wooden cladding.

Versatile arrangements are also possible within the apartments themselves. Adaptable buildings are becoming increasingly important, as city dwellers are expressing a demand for apartments and workplaces that can respond quickly to changes in family structure and jobs. Rooms and apartments have to be expandable, while also offering the option to partition or reduce them in size again at a later date. Case Study #1 Hamburg is conceived in such a way that the dimensions of the rooms vary from 45 square metres (“micro-lofts”) to 140 square metres (“macro-lofts”). Every apartment is also guaranteed access to a garden and roof terrace.

Energy Concept: Integration into the Wilhelmsburg Central Energy Network

The energy concept behind Case Study #1 Hamburg is based on the Energieverbund Wilhelmsburg Central Energy Network. In this system, energy plants in different buildings are interconnected to form a large, “virtual” power plant. The resulting heat grid is accessible to all those who supply it with renewable heat. The Wilhelmsburg Central Energy Network is thus making a significant contribution to efficient energy supply and to climate protection on the Elbe islands. Case Study #1 Hamburg receives district heating from the energy grid, which is linked up to a fresh-air heating system that provides controlled ventilation and heating with heat recovery.
