Current planning and design modes of dwellings and neighbourhoods are facing challenges of both philosophy and form. Past approaches no longer sustain new demands and require innovative thinking. The need for a new outlook is propelled by fundamental changes that touch upon environmental, economic and social aspects.

The depletion of non-renewable natural resources, elevated levels of greenhouse gas emissions and climate change are a few of the environmental challenges that force designers to reconsider conceptual approaches in favour of ones that promote a better suitability between communities and nature. Consideration of overall planning concepts that minimize the development's carbon footprint, district heating, passive solar gain, net-zero residences and preserving the site's natural assets are some of the contemporary strategies that architects, planners and builders are integrating into their thought process and residential design practice.

Increasing costs of material, labour, land and infrastructure have posed economic challenges with affordability being paramount among them. The need to do with less brings about concepts that include denser places, adaptable and expandable dwellings, and smaller-sized yet quality designed housing. Also, the need to reduce utility costs gave rise to better insulation, which benefits both the environment and the occupant.

Social challenges are also drawing the attention of designers, builders and homeowners. As the "baby-boom" generation plans for retirement, housing an elderly population will take priority. Walkable communities, ageing in place and multigenerational living are some of the concepts considered. In addition, live-work environments have become part of the economic reality for those who wish to work from home - which has become possible through digital advances.

The need to think innovatively about neighbourhoods led to the idea to write this book. The intention is to offer information on contemporary community design concepts and illustrate them with outstanding international examples.
