Part of the architectural profession, and also some non-architects, responded to Modernism and Postmodernism by going to what they considered the root of the problem. They felt that architecture was not a personal philosophical or aesthetic pursuit by individualists; rather it had to consider everyday needs of people and use technology to give a livable environment. The Design Methodology Movement involving people such as Christopher Alexander started searching for more people-oriented designs. Extensive studies on areas such as behavioral, environmental, and social sciences were done and started informing the design process. As many other concerns began to be recognized and the complexity of buildings began to increase (in terms of aspects such as structural systems, services and technologies), architecture started becoming more multi-disciplinary than ever. Architecture today usually requires a team of specialist professionals, with the architect being one of many, although usually the team leader.
During the last two decades of the twentieth century and into the new millennium, the field of architecture saw the rise of specializations within the profession itself by project type, technological expertise or project delivery methods. In addition, there has been an increased separation of the 'design' architect[a] from the 'project' architect[b] within some architectural office collaborations.
One of most significant recent developments in the profession is the mainstreaming of sustainability. Sustainability in architecture was pioneered in the 1970s by architects such as Ian McHarg in the US and Brenda and Robert Vale in the UK and New Zealand. The acceleration in numbers of buildings which seek to meet sustainable design principles is inline with a growing world-wide awareness of the risks of climate change. It is now widely expected of an architect that they will integrate sustainable principles into their projects. (from http://en.wikipedia.org/wiki/Architecture) Photo by Santiago Calatrava
