Article Citation - WoS: 13Citation - Scopus: 14Investigating Space Utilization in Skyscrapers Designed with Prismatic Form(Mdpi, 2024) Ilgin, Hueseyin Emre; Aslantamer, Ozlem NurThe enduring appeal of prismatic shapes, historically prevalent in office building designs, persists in contemporary skyscraper architecture, which is attributed particularly to their advantageous aspects concerning cost-efficiency and optimal space utilization. Space efficiency is a crucial factor in prismatic skyscraper design, carrying substantial implications for sustainability. However, the current academic literature lacks a complete exploration of space efficiency in supertall towers with prismatic forms, despite their widespread use. This paper seeks to address this significant gap by conducting a comprehensive analysis of data gathered from a carefully selected set of 35 case studies. The primary discoveries presented in this paper are outlined as follows: (i) average space efficiency stood at approximately 72%, covering a range that extended from 56% to 84%; (ii) average core to gross floor area ratio averaged around 24%, spanning a spectrum that ranged from 12% to 36%; (iii) the majority of prismatic skyscrapers utilized a central core approach, mainly customized for residential use; (iv) the dominant structural system observed in the analyzed cases was the outriggered frame system, with concrete being the commonly utilized material for the structural components; and (v) the impact of diverse structural systems on space efficiency showed no significant deviation, although differences in function led to variations in average space efficiency. The authors expect that these findings will provide valuable guidance, especially for architects, as they strive to enhance the sustainable planning of prismatic towers.Article Yeni bir Yapı Tipolojisini Keşfetmek: Yapısal Hibritler(2025) Ilgın, Hüseyin Emre; Aslantamer, Özlem NurIn recent years, the increasing demand for iconic towers, coupled with intense competition among major cities to construct the most distinguished vertical structures and the continuous pursuit of building the world’s loftiest structures, has come to characterize the forefront of modern high-rise architecture. In this race, many vertical structures have essentially become vertical extensions of land, primarily aimed at maximizing the financial value of the ground they occupy. However, this approach has often resulted in the proliferation of uninspiring and homogeneous towers across the globe, largely products of isolated architectural practices. Despite nearly 150 years of innovation, the architectural design of high-rise buildings has yet to fully achieve the desired advancement, particularly in terms of urban integration and structural design. In this study, the authors propose a classification system for contemporary high-rise typologies, with a particular focus on hybrid structures. The study underscores the importance of spatial quality and the integration of structural design, aiming to raise architects' awareness of structure as a fundamental element of architecture. Structural hybrids offer a transformative approach to high-rise design by integrating structure and architecture to overcome the limitations of standardized designs, creating dynamic and contextually enriched spaces.Article Citation - WoS: 7Citation - Scopus: 8Evaluating Space Efficiency of Tall Buildings in Turkey(Mdpi, 2024) Aslantamer, Ozlem Nur; Ilgin, Huseyin EmreIn response to the increasing building demands in Turkey, particularly in the metropolitan area of Istanbul, followed by other major cities such as Ankara and Izmir, the expansion of construction zones has led to the emergence of tall towers as a pragmatic solution. The design and implementation of tall buildings require newer technologies and interdisciplinary collaboration in aspects such as facade installation, vertical circulation solutions, and fire systems, compared to low-rise buildings. In spite of the proliferation of skyscrapers, there is a noticeable lack of thorough study on space efficiency in Turkey's tall buildings. This article aims to fill this significant gap in the literature. The research method employed in this study focuses on a case study of 54 modern towers constructed in Turkey between 2010 and 2023, ranging in height from 147 to 284 m. Key findings are as follows: (1) residential use, central core, and prismatic forms are the most prevalent architectural preferences; (2) the most preferred structural material and system are concrete and the shear-walled frame system, respectively; (3) average space efficiency and the percentage of core-to-gross-floor area (GFA) were 78% and 19%, respectively, with measurement ranges varying from a minimum of 64% and 9% to a maximum of 86% and 34%. This paper will provide insight for construction stakeholders, especially architects, for sound planning decisions in the development of Turkish tall buildings.Article Shanghai's High-Rise Buildings: Exploring Space Efficiency, Structural Systems, Forms, Materials and Core Designs(Taylor & Francis Ltd, 2026) Aktas, Kurt Orkun; Aslantamer, Ozlem Nur; Aktas, Gozen Guner; Ilgin, Huseyin EmreThis study examines the architectural and structural design considerations influencing space efficiency in Shanghai's high-rise buildings. Understanding space efficiency is significant because it directly affects land-use intensity, economic returns, and sustainability outcomes. The objective of this study is to quantify space efficiency ratios by analyzing the relationships between core types, function, form, and structural systems, and assess temporal and comparative benchmarks for Shanghai within the global context. The novelty lies in its combined focus on architectural and structural determinants of space efficiency, supported by data on 43 high-rise buildings in Shanghai. Methodologically, this study relies on quantitative analysis of Net Floor Area (NFA), Gross Floor Area (GFA), and core ratios, supplemented with comparative evaluation of building forms, materials, and structural systems. The key findings reveal: (1) average space efficiency at 75% with core-to-GFA ratios of 23%, varying between 52-93% and 5-33% respectively; (2) the dominance of prismatic forms supported by composite outriggered frame systems; (3) a decline in efficiency with increasing building height due to larger service cores. Practically, this research highlights opportunities for stakeholders - including architects, engineers, and policymakers - to adopt lightweight materials, prefabrication techniques, and smart building systems that improve space efficiency in future high-rise developments.Article Evaluation of Space Efficiency, Structural Systems, Material Applications, and Design of High-Rise Structures in South Korea(Highlights of Science, 2025) Aktaş, K.O.; Zaim, A.; Aslantamer, Ö.N.; Aktas, G.G.; Ilgın, H.E.This study examines 61 South Korean towers, analyzing their architectural configu-rations, structural systems, material applications, and spatial efficiencies. Findings indicate a pre-dominance of central core configurations and prismatic forms, reinforcing a function-driven approach to vertical urbanism. Structural system preferences highlight the widespread use of out-riggered frames, ensuring lateral stability while optimizing floor layouts. Material selection trends reveal a reliance on concrete, aligning with global patterns, while composite materials (25%) are used in high-performance supertall structures. Functionally, residential high-rises dominate, with mixed-use (2%) and office towers (11%) remaining limited. This research also identifies an aver-age spatial efficiency of 76%, aligning with international benchmarks, though variations exist across cities due to core-to-gross floor area ratios, structural constraints, and service core alloca-tions. This research underscores South Korea’s strategic high-rise development, prioritizing space optimization, structural efficiency, and economic feasibility. However, opportunities re-main for increased functional diversity, broader hybrid material adoption, and greater integration of sustainable design innovations. These findings contribute to global skyscraper analysis, offering insights into high-rise architecture’s role in urban resilience and density management. © 2025 Aktaş et al.Article Citation - WoS: 9Citation - Scopus: 12Space Efficiency in Timber Office Buildings(Elsevier, 2024) Aslantamer, Ozlem Nur; Ilgin, Huseyin EmreTimber offices indicate a growing field, principally thanks to their potential to offer noteworthy ecological and financial gains over their entire life. Like many other building types, space efficiency is a crucial design parameter in timber structures to ensure a project's feasibility. This factor is especially significant in office buildings, where maximizing rental income reflects effective planning. Currently, there is a lack of exhaustive inquiry providing a thorough insight of space efficiency in modern timber office buildings. This study fills this gap in the literature by collecting data from 33 buildings through literature reviews and case study method to investigate space efficiency with the key architectural and structural factors that influence it. The results showed that: (i) central cores stood out as the prevailing core layouts, while peripheral arrangements were noted as alternative preferences. Prismatic shapes emerged as the most favored options; (ii) timber was extensively used as a primary building material, closely followed by combinations of timber and concrete. Load-bearing systems mainly relied on shear walled frames and configurations; (iii) average space utilization across examined cases was 88 %, with variances ranging from 75 % to 95 % among different instances; (iv) average ratio of core area to GFA was 10 %, showing variations between 4 % and 19 % across various scenarios; and (v) there were no substantial variances noted in the effect of different core planning strategies on spatial efficiency. Similar conclusions were drawn regarding building forms and structural materials. Our paper will assist in crafting design principles customized for diverse stakeholders, including architectural designers of timber offices.Article Citation - WoS: 4Citation - Scopus: 5Space Efficiency in Tall Hotel Towers(Mdpi, 2024) Aslantamer, Ozlem Nur; Ilgin, Huseyin EmreMaximizing spatial utilization within tall buildings stands as a paramount planning consideration for ensuring project feasibility, particularly accentuated ins the context of hotel constructions. To date, no comprehensive study has addressed this issue while considering crucial architectural and structural planning factors. This article fills this gap by using a case study method based on data from 31 contemporary tall hotel towers. The findings revealed several key points: (i) central core typology was mostly utilized; (ii) prismatic buildings were the most prevalent forms; (iii) shear-walled frame systems were predominantly employed; (iv) concrete was the preferred choice for hotel construction; (v) the average space efficiency and the ratio of core area to gross floor area (GFA) averaged 81.2% and 16%, respectively; (vi) the range changed from a minimum of 70% to 4% to a maximum of 94% to 28%; and (vii) space efficiency showed an inverse relationship with the height of the building. It is anticipated that this paper will assist architects and structural engineers as well as builders involved in the planning of hotel developments.Article Exploring the Impact of Landscape Design on User Preferences in Shopping Centers Post the Covid-19 Pandemic(2024) Aslantamer, Özlem Nur; Ilgın, Hüseyin EmreThis study explores the impact of landscape design, which has gained importance alongside architectural changes in shopping centers, and investigates preferences in the post-COVID-19 pandemic era. Although e-commerce has increased during the pandemic, research and societal behaviors suggest that shopping centers will continue to serve as contemporary agoras due to their socialization and leisure functions. However, in response to the pandemic, it is anticipated that newly designed shopping centers will be architecturally conceived as semi-outdoor or outdoor spaces, regardless of climate conditions. This transformation will involve the softening of rigid appearances through landscape elements, making them both ecologically and psychologically sustainable. The number of studies on this subject is limited. To address this knowledge gap, an online survey was conducted with 586 randomly selected users across nine shopping centers located in three major cities of Turkey: Istanbul, Ankara, and Izmir, with three shopping centers in each city. The survey investigated users' preferences for architectural styles (indoor, semi-outdoor, or outdoor) and landscape design in shopping centers. The findings of the study indicate that post-pandemic, outdoor and semi-outdoor shopping centers are likely to be preferred more frequently. An emphasis is likely to be placed on natural landscape elements such as plants and water features in landscape design. Furthermore, shopping center designs are likely to become simpler, offering comfortable and spacious navigation areas while optimizing parking and transportation conditions. This study is expected to shed light on decision-making processes for future shopping centers. By incorporating consumer preferences, architects can enhance the sustainability of shopping center investments through next-generation design.Article Citation - WoS: 10Citation - Scopus: 12Analysis of Space Efficiency in High-Rise Timber Residential Towers(Mdpi, 2024) Ilgin, Hueseyin Emre; Aslantamer, Ozlem NurHigh-rise timber residential towers (>= eight-stories) represent a burgeoning and auspicious sector, predominantly due to their capability to provide significant ecological and financial advantages throughout their lifecycle. Like numerous other building types, spatial optimization in high-rise timber residential structures stands as a pivotal design factor essential for project viability. Presently, there exists no comprehensive investigation on space efficiency in such towers. This study analyzed data from 51 case studies to enhance understanding of the design considerations influencing space efficiency in high-rise timber residential towers. Key findings included (1) the average space efficiency within the examined cases was recorded at 83%, exhibiting variances ranging from 70% to 93% across different cases, (2) the average percentage of core area to gross floor area (GFA) was calculated at 10%, demonstrating fluctuations within the range of 4% to 21% across diverse scenarios, and (3) no notable distinction was observed in the effect of various core planning strategies on spatial efficiency when properly designed, and similar conclusions were drawn regarding building forms and structural materials. This research will aid in formulating design guidelines tailored for various stakeholders such as architectural designers involved in high-rise residential timber building developments.Article Citation - WoS: 7Citation - Scopus: 10Space Efficiency in North American Skyscrapers(Mdpi, 2024) Ilgin, Huseyin Emre; Aslantamer, Ozlem NurSpace efficiency in North American skyscrapers is crucial due to financial, societal, and ecological reasons. High land prices in major cities require maximizing every square foot for financial viability. Skyscrapers must accommodate growing populations within limited spaces, reducing urban sprawl and its associated issues. Efficient designs also support environmental sustainability and enhance city aesthetics, while optimizing infrastructure and services. However, no comprehensive study has examined the key architectural and structural features impacting the space efficiency of these towers in North America. This paper fills this gap by analyzing data from 31 case study skyscrapers. Findings indicated that (1) central core was frequently employed in the organization of service core; (2) most common forms were setback, prismatic, and tapered configurations; (3) outriggered frame and shear walled frame systems were mostly used; (4) concrete was the material in most cases; and (5) average space efficiency was 76%, and the percentage of core area to gross floor area (GFA) averaged 21%, from the lowest of 62% and 13% to the highest of 84% and 31%. It is expected that this paper will aid architectural and structural designers, and builders involved in shaping skyscrapers in North America.
