Conversion of Bunkers into Residential Spaces
The document discusses the transformation of former military bunkers into modern residential spaces. The conversion process involves significant demolition work to introduce light into the previously windowless structures. This requires removing large amounts of concrete using specialized techniques, such as rope saws with industrial diamonds, similar to those used in marble mining. The concrete is then repurposed for road engineering.
Challenges and Solutions
One of the main challenges is maintaining the historical integrity of the buildings while modernizing them. In Munich, for example, the external appearance of a listed bunker had to be preserved, necessitating innovative lighting solutions to illuminate the interior. The conversion process is technically demanding and time-consuming, often taking over six months.
Appeal of Bunker Living
The unique architectural features, such as thick walls and large window embrasures, offer a sense of safety and individuality. The absence of load-bearing walls allows for flexible interior design. The central urban locations of these bunkers, originally built during World War II, add to their desirability.
High-Rise Buildings: Historical Context and Modern Developments
The document also explores the evolution of high-rise buildings, starting with the Home Insurance Building in Chicago, which introduced metal structures for fire safety and reduced weight. The development of skyscrapers in New York, such as the Chrysler Building and Empire State Building, is highlighted as a symbol of architectural progress and economic power.
Regulations and Design Innovations
Regulations like the 1916 Zoning Resolution in New York led to the introduction of setbacks in skyscraper design, allowing for more light and air. The document notes a shift in high-rise design towards more aesthetic and functional considerations, with examples like the Norra Tornen in Stockholm, which feature a cube-based design to break away from traditional uniformity.
Conclusion
The document concludes by emphasizing the ongoing evolution of high-rise architecture, with new designs focusing on individuality and breaking conventional norms, as seen in projects like the Norra Tornen.
Overview of Pentridge Prison Redevelopment
The document discusses the transformation of the historic Pentridge Prison in Melbourne, Australia, into a modern residential and commercial hub. Originally established in 1851, the prison housed notorious criminals until its closure in 1997. The redevelopment aims to preserve the site's heritage while revitalizing the Coburg district.
Historical Background
Pentridge Prison expanded significantly between 1857 and 1864, with facilities for prisoner labor in various trades. The prison witnessed significant events, including the last execution in Australia in 1967 and a riot in 1970. The high-security Jika Jika complex was closed after a fatal fire in 1988, leading to the prison's eventual closure in 1997.
Redevelopment Efforts
The redevelopment project, led by Shayher, emphasizes preserving the site's historical significance. The Coburg Horizons, designed by PRO-ARK, are among the first projects completed. These residential buildings incorporate historical elements, such as basalt stones from the original prison, into their modern design.
Architectural Design
The Coburg Horizons feature a blend of historical and modern architectural elements. The use of basalt stones in the façade and historical photos as decorative panels highlights the site's heritage. The buildings also incorporate modern materials like RECKLI formliners and NAWKAW color systems to enhance durability and aesthetics.
Infra-lightweight Concrete
The document also explores the potential of infra-lightweight concrete (ILC) in construction. Developed at TU Berlin, ILC combines low bulk density with high strength, making it suitable for multi-storey structures. It offers advantages in terms of energy efficiency, design flexibility, and sustainability.
Applications and Benefits
ILC allows for monolithic designs that integrate load-bearing and insulation functions, reducing construction complexity and enhancing durability. Its use in multi-storey buildings is being explored through research projects like INBIG, which focus on material-specific design approaches.
Félix Candela's Contributions
The document concludes with a profile of Félix Candela, an architect known for his work with thin-shell structures. Candela's innovations in hyperbolic paraboloid roofs have influenced modern architectural design, emphasizing elegance and material efficiency.
Introduction to Candela's Architectural Innovations
Felix Candela, a renowned architect, is celebrated for his innovative use of the hyperbolic paraboloid (hypar) roof design. His work on the Pabellón de Rayos Cósmicos at the University of Mexico City marked the beginning of his exploration into this architectural form, which is both aesthetically pleasing and cost-effective due to its minimal material requirements.
Notable Projects and Designs
One of Candela's masterpieces is the Los Manantiales restaurant in Xochimilco, Mexico City. This structure features four intersecting hypar roof shells, resembling flower petals. The construction utilized straight wood formwork and a V-shaped steel-reinforced structure to support the weight, showcasing Candela's ingenuity in design and construction.
Candela's signature hypar roofs were adapted for various industrial and religious buildings, such as the Rios factory hall and the Iglesia de la Medalla Milgrosa. His designs often incorporated skylights and asymmetrical elements to enhance functionality and aesthetic appeal.
Legacy and Final Works
In the latter part of his career, Candela took on teaching roles, eventually moving to the USA. His final major project, L’Oceanogràfic in Valencia, Spain, was completed posthumously and stands as a testament to his visionary approach to architecture.
RECKLI's Contribution to Architectural Concrete
Founded in 1968, RECKLI has become a leader in architectural concrete, known for its innovative formliners that enhance the visual appeal of concrete surfaces. The company was established by Hans Jürgen Wiemers, who was inspired by the potential of concrete as a design element. RECKLI's formliners are used globally, allowing architects to create unique and imaginative structures.
Innovations in Concrete Formwork
RECKLI's success is rooted in its development of elastic structural formliners, made from a two-component polyurethane. This innovation allows for detailed and flexible concrete designs, overcoming the visual defects commonly associated with exposed concrete.
Conclusion
Both Felix Candela and RECKLI have significantly influenced modern architecture through their innovative approaches to design and material use. Candela's hypar roofs and RECKLI's formliners continue to inspire architects worldwide, demonstrating the enduring impact of their contributions to the field.
Introduction and Background
The document discusses the challenges faced by concrete processors and the innovative solutions developed by Wiemers and Ernst, leading to the founding of RECKLI K.G. in 1968. The company aimed to improve the aesthetic design of concrete to avoid costly repairs.
Development of Elastic Formliners
Wiemers and Ernst faced the challenge of developing production processes for elastic formliners without existing models. They had to determine dimensions, material properties, and production technology. Initial production was manual, leading to the establishment of production standards after extensive testing.
Product Launch and Market Expansion
The first formliner was successfully used in 1968, leading to the development of various patterns and structures. RECKLI expanded its market through marketing efforts, including an information movie and participation in trade fairs. By 1971, the company had partnerships across Europe and later expanded globally.
Innovative Projects and Applications
RECKLI's products have been used in various innovative projects, including the encapsulation of a Mercedes G-class in synthetic resin for a marketing campaign. This project involved complex processes to ensure the car was preserved without deformation.
Global Influence and Custom Solutions
RECKLI has established itself as a leader in architectural concrete design, with a presence in multiple countries. The company provides custom solutions and has expanded its applications beyond formliners to include replicas, mold-making, and more.
Conclusion
RECKLI continues to innovate in the field of architectural concrete, maintaining the founding principles of craftsmanship and quality. The company's global reach and diverse applications highlight its significant impact on the construction and design industries.
