RSAA | sustainable architecture and urban design

We are an international architecture and urban design studio drawing on the design, planning and construction experience from 50 years of practice. Combining the expertise of architects and urban planners, we pursue an interdisciplinary and holistic approach to design, based on a comprehensive understanding of the planning process. Our practical experience is supported and enhanced by international and domestic teaching and research activities. We value and apply sustainable planning and design principles and focus on developing planning solutions that are specifically tailored to the local context and each client’s needs.

  • 13 08 2011 We are commissioned with masterplan for Shanghai low-carbon farm

    Schaller2We have been commissioned with a 108ha master plan for a low-carbon farm on Chongming Island, Shanghai. It will be the second site for the famous Shanghai organic brand “Tony’s Farm”. The design will combine highly innovative organic agricultural production with hospitality uses, and thus make organic farming tangible to Shanghai’s city dwellers. The project was launched at an official press conference in the presence of government officials including the mayor of Chongming.

    In the words of our design director Christian Schaller:

    “Tonys farm will demonstrate that its innovative approach to industrialized agrarian production can be realized in harmony with a landscaping that respects the structure of the site, its geological formation, the exposure to the elements shaping it and the cultural traces left from past generations. It is by no means intended to design a nostalgic reproduction of the past. The aim is to create a modern type of agrarian landscape, demonstrating that the realization of the necessary facilities, buildings and infrastructures can be integrated in such a way that through innovative design,the result has the same quality as historical agrarian landscapes.”

In the direct sense, ecology- interpreted as the symbiosis of individual phenomena in a balanced whole- points to a self-regulating system of plants, animals and human beings. In an allegorical sense, it points to the synergetic inclusion of manifold aspects and challenges in a complex and sustainable design.


Sustainability as an objective of planning interventions means to improve a situation by means of this intervention and to extend its purpose into the future. This is achieved by means of planning strategies that include long-term perspectives, a clear objective as well as economic and efficient use of resources (material as well as intellectual).

Human Scale

The human scale is the basic measure of the spatial notion on which the European city is based. It leads to ordered, clearly readable spatial arrangements, in urban design as well as in architecture. Urban spaces, homes and rooms are seen as system of circulation, spaces for dwelling and views, that can be discovered again and again.

Genius Loci

The location, interpreted as the origin and criteria of any specific intervention- developed from it and respectful of it. A new, particular place is created that is based on the interplay of the past and existing with the new.
