Current design of apartment buildings is facing challenges of 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, cultural and social aspects that led to the writing of this book. The depletion of non-renewable natural resources and climate change are a few of the environmental challenges that prompted designers to reconsider conceptual approaches in favour of ones that promote a better suitability between buildings and their environments. Concepts that minimize the building's carbon footprint, passive solar gain, net-zero structures and water harvesting system are some of the contemporary strategies that architects and builders are integrating into their thought processes and design. 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 adaptable dwellings, and smaller-sized yet quality designed housing. Social challenges are also drawing attention. As the ba- by-boom generation plans now for retirement, housing an elderly population will take priority. Walkable communities, aging in place, live-work residences, and multigenerational living are some of the concepts considered. The book offers information on contemporary design concepts and illustrates them with plans and photographs of outstanding international examples.
