Nested Fabric Adaptation to New Urban Heritage Development

Abstract

Old urban reform usually reactivates the urban fabric in a new era of sustainable development. However, what remains of the former fabric and how it interacts with the new one often inspires curiosity. How the old residents adapt their lives to the new layout should be explored qualitatively and quantitatively. This research aimed to assess the old and new fabrics in the downtown area of Keelung, Taiwan, by considering the interactions between truncated layout, proportion, and infill orientation in the mature and immature interfaces. According to the historical reform map made in 1907, the newly constructed area occupied the old constructed area in seven downtown blocks. On average, the area composed of new buildings ranged from 135.60% to 239.20% of the old area, and the average volume of the buildings reached a maximum of 41.72 m when compared to the old buildings in place prior to the reform. It seems that the new fabric purposefully maintained the old temples at the centers of the blocks. However, the old alleys, which still remain within these blocks, have been significantly overloaded with services and have become auxiliary utility spaces for the in-block residences. With regard to the part of the fabric that was truncated or reoriented by new streets, the modification could also be easily found on the second skin. A physical model analysis used a UAV 3D cloud model and QGIS® to verify the axes, hierarchies, entrances, open spaces, and corners in the commission store block and temple blocks. We found that the 3D point model and historical maps presented a convincing explanation of the evolved fabric from the past to the present. The stepwise segmentation visualizes the enclosed block inside a block on the historical maps and according to the present sections. We found that new roles for old alleys have evolved behind the new fabric.

A Study on Tourist Satisfaction Based on the Conservation and Reuse of Alleyway Spaces in Urban Historic Neighborhoods

“…After a century of development since the mid-19th century, various charters and laws gradually emerged, accompanied by the emergence of various preservation theories. Scholars both domestically and abroad have shown two common trends in the research and practice of historical cultural neighborhoods: the preservation trend has shifted from the original focus on updating and developing the protection of historical neighborhoods and exploring the spatial forms [20,21], texture [22], and structure [23] of historical neighborhoods at the material environmental level to the regional studies of urban memory [24], regional culture [25,26], historical streets and alleys [27], and regionally oriented research on cultural environmental aspects and humancentered non-material aspects, emphasizing cultural heritage. In terms of preservation methods, an increasing number of scholars are using visualization analysis software for more accurate quantitative assessments, guiding the renewal and activation of historical cultural neighborhood spaces.…”

Inspecting Pond Fabric Using Unmanned Aerial Vehicle-Assisted Modeling, Smartphone Augmented Reality, and a Gaming Engine

“…People have created an extensive tangible network of infrastructure, buildings, and urban forms around water [10]. Land can be regarded as an engine for regional growth in terms of tourism, services, and infrastructure [11], and the transition of land use can exemplify the complexity of urbanization [12][13][14][15] over a period of 100 years [16].…”
