2 / 14 slope analysis

This project is the result of a collaboration with the Design and Research Institute of Hunan University. The Institute had been working for several months on the masterplan of Jianshi, a small city located in a mountainous area of the Hubei province. Our task was to analyze and assess the potentials and weaknesses of the existing proposal and provide possible alternatives.


3 / 14 slope analysis: classification

The city is planned to expand from 50.000 to 200.000 inhabitants in the next 10 years, practically occupying the totality of the available flat land that is currently used for agricultural production. As a result of such expansion the economy of the city is also meant to evolve from primary to secondary and tertiary industry, generating an important and potentially violent rupture with its traditional identity.

在接下來的十年里,堅石市人口將由如今的5萬增長至20萬,若維持現有的城市密度, 城市化將會吞噬掉現有平坦區域上的耕地。隨著人口增長,城市經濟發展目標也將由第一產業向第二、第三產業轉移,堅石市也將不可避免的面臨與傳統特征割裂的局面。

4 / 14 water run-off and accumulation

Although the infrastructure and the urban fabric are carefully designed, taking into consideration the particular morphology of the terrain, and the functional distribution avoids most of the typical problems related to mono-functional zoning, the original masterplan seems to lack a clear phasing strategy and does not take full advantage of the potentials of the natural context.


5 / 14 landslide control: water run-off and slope analysis

Thus we elaborate a scheme that is in-formed by the materiality of the site, constituting an energetic material assemblage that can build-up a dialogue between the topography, the soil and the hydrology of the site on the one hand and the functionality and quality of the urban space on the other. We propose a system of synergies in which the urban fabric is spatially and symbiotically articulated over the natural environment, actively enhancing its potentials.


6 / 14 soil quality

Within an integrated system of green corridors, the productive landscape then becomes an important element of the public space. Analyzing the quality and productivity of the landscape, we are able to create a sequence of spatial transformations that preserves the most valuable natural elements and allows a smoother transition from the rural to the new urban economy.


7 / 14 water run-off concentration

In terms of design process, we divided our research in two branches, natural and artificial, which are then re-described as a single system of qualities, quantities and performances - i.e. intensities. Through the indexing* of the site we generate maps and diagrams that are the graphic translation of specific systems of relations. * for a deeper understanding of the term and methodology, please refer to the 羽毛球拍专卖 section

在設計過程中,我們將研究劃分為兩大分支:自然系統和人工系統,并最終將這兩個系統用統一的參數來歸納和描述:質量,數量,功能,強度。通過對地段的參數化分析 若要深入了解,請參見 學術部分首頁 section

8 / 14 soil productivity evaluation

We generate maps and diagrams that are the graphic translation of specific systems of relations.
The quantity and qualities extracted from the analysis of different layers are then dissected and recombined to produce a more comprehensive and holistic knowledge of the territory.


9 / 14 existing conditions: built fabric

The soil productivity is evaluated through the combination of: slope analysis, accessibility and developable areas; water run-off, possible water collection systems and potential hazards; soil quality and solar radiation levels.


10 / 14 proposed road network: slope evaluation

The configuration of the green corridors is then mediated by the existing vegetation, the main infrastructure and a logic of spatial sequences related to the public space. Finally the road network is punctually redesigned in order to generate loops that allow an easier implementation of the public transportation system.
