The expression of each roof of the building is different, while at the same time having exclusively for its own spaces or activities. Away from the hustle of daily life, the independent roof spaces appeared to be the second layer of urban landscape floating in the air, which has named “Roof-Scape” in this research. The realm expansion depending on individual needs presents an informal construction system of annex, neglecting either the regularity of the city or legal rules. Therefore, the exploration of reason and space type of the architectural roof space construction in Taiwan framed the intention of this research.
Field study on regional roof type, structure, materials and functions has recorded with photographs and models. Observation database classification suggested some basic elements of the existing buildings. The keynote of the design operation in this research is to develop a new space plan according to these basic elements. The attempt of breaking rules and trying to implant a new type of space plan in the framework of existing roof space program has operated in three stages. Stage one, remodeling the roof spaces in respect of the use of parametric design tools discussing the possibility of different spatial scales and forms. Stage two, discussing space within living behavior, using three different residential scales with parametric design tools to explore the possibility of different types of roof residential space. Stage three, developing the new form of roof space under the view of urban landscape with four actual sites of four different scales.
The anticipation of this study is in an attempt to establish the possibility of another kind of urban renewal strategy under the framework of the existing urban roof space. There is an expectation to provide new attitudes and ideas for urban renewal, and keep the public interest to continue to study for the future.
