The 425th issue of ‘C3’ explores various architectural concepts with expert contributors from around the world. The concept of architecture as a vision machine is explored in ‘The Observatory’, emphasising how it influences our perspectives. In ‘Truly at Home in the Landscape’, houses are discussed as entities that interact with the land they occupy. Demonstrating respect towards the land is crucial, as it provides a sanctuary for humanity. ‘Contextualising the Community Library’ highlights the importance of local libraries fitting in with their surroundings. Architects can achieve this by considering the existing built environment, street plan, topology, or landscape.
