“…Metzer, 2006). However, what clearly emerged is that the concept of void covers a large spectrum, with tangible and intangible features at each extremity, well summarised by Sileryte et al. (2017): “Urban architectural void is a three-dimensional continuous space in between physical and perceptual limits, both explicit and implicit, that emerge in urban environments.” (p. 3).…”

PurposeThe aim of this article is to understand the definitions, trends and gaps currently existing in the literature regarding the concept of void in the built environment.Design/methodology/approachThe method used for this article is based on a bilingual narrative literature review, the authors being fluent both in French and English. The advantage of any literature review is that it allows researchers to gather and analyse existing academic literature on a specific subject. The chosen technique gives a thorough understanding of the study and helps in identifying research gaps. The literature review was sequential, online and used ScienceDirect, Scopus and Sage Knowledge as databases.FindingsThere are three main findings regarding this literature review. The first shows that the void is lacking consensus regarding its definition and attributes, yet this is unanimously considered as an existing space in the city. The second finding shows that voids are talking to our emotions and perceptions and more studies could investigate a new planning/design approach in taking this into consideration. At last, the third findings shows that there are some gaps that need to be further researched, such as the difference between Western and Eastern cultures to use voids in architecture.Originality/valueIn compiling 35 articles focussing on the void, this article proposes a valuable source of knowledge regarding this topic, as well as delineates new research directions.

“…References [135,136] report a model to subdivide continuous urban spaces into convex and solid voids (3D volumes) for analysis and classification based on physical measures, in which outdoor is roughly classified as urban void and the subdivision procedure is conducted based on convex polygon. Reference [137] proposes a versatile data model for analysing urban architectural void, in which space compartmentalization is conducted based on Gestalt theory and its model can be rendered both as a 2D and 3D representation.…”

In spatial science and urban applications, “space" is presented by multiple disciplines as a notion referencing our living environment. Space is used as a general term to help understand particular characteristics of the environment. However, the definition and perception of space varies and these variations have to be harmonised. For example, space may have diverse definitions and classification, the same environment may be abstracted/modelled by contradicting notions of space, which can lead to inconsistencies and misunderstandings. In this paper, we seek to investigate and document the state-of-the-art in the research of “space” regarding its definition, classification, modelling and utilization (2D/3D) in spatial sciences and urban applications. We focus on positioning, navigation, building micro-climate and thermal comfort, landscape, urban planning and design, urban heat island, interior design and planning, transportation and intelligent space. We review 147 research papers, technical reports and on-line resources. We compare the presented space concepts with respect to five criteria—classification, boundary, modelling components, use of standards and granularity. The review inventory is intended for both scientists and professionals in the spatial industry, such as companies, national mapping agencies and governments, and aim to provide a reference to better understand and employ the “space” while working across disciplines.

“…Beirão, Chaszar, and Cavić () and Beirão, Chaszar, and Ljiljana () report a model to subdivide continuous urban spaces into convex and solid voids (3D volumes) for analysis and classification based on physical measures, in which outdoor space is roughly classified as urban void and the subdivision procedure is conducted based on convex polygons only. Sileryte, Cavic, and Beirao () propose a versatile data model for analyzing urban architectural voids, in which space compartmentalization is conducted based on gestalt theory. However, it is also not sufficient for navigation use, because: (a) the space is subdivided by using geometric tricks only; and (b) subspaces are also represented in 2D.…”

Outdoor navigation is widely used in daily life, but faces various issues related to the fidelity of outdoor navigation networks. For instance, agents (pedestrians) are often guided via unrealistic detours around places without clear paths (e.g., squares) or if there are vertical constraints such as overpasses/bridges. This is partly explained by the fact that the main sources of navigation networks in current outdoor navigation are two‐dimensional road/street networks. Utilizing a three‐dimensional space‐based navigation model, compatible with some indoor approaches, is a popular way to address the above‐mentioned issues. A 3D space‐based navigation model is generated by treating 3D spaces as nodes and the shared faces as edges. Inputs of this model are enclosed 3D spaces (volumes). However, outdoor spaces are generally open and unbounded. This article puts forward an approach to enclose outdoor spaces and mimic the indoor environments to derive a network based on connectivity and accessibility of spaces. The approach uses 2.5D maps and consists of three major steps: object footprint determination, footprint classification and space creation. Two use cases demonstrate the proposed approach. Enclosing outdoor spaces opens a new research direction toward providing seamless indoor/outdoor navigation for a range of agents.
