Abstract-Natural beauty goes beyond standards and cliches which needs to be stored for future generations to enjoy it in its best form. The quest for sustainability in context of nature and environment directs anthropoid to adapt the new conspicuous ideology of 'Flexible Architecture' that believes in responding to change rather than staying idle. The Flexible Buildings is a new genre of Architecture which believes in full utilization of existing resources, willingness to embrace changes and challenges by profound utilization of new technology aided by the computer technology support. The unconventional Flexible architecture is capable of defying worldly and environmental challenges such as melting of ice, rise in sea level, migration of refugee, global warming, dense population in cities, disastrous events etc, while aesthetic consideration is also given due importance parallely.Flexibility in architecture was introduced by Walter Gropius in 1950s which has progressed to a more advance level in few decades. A lot of research has been conducted in this field, which largely describes contemporary flexible architecture as designed for multipurpose utilization. Global consumerism, availability of materials and new technology adopted play a vital role in its world wide acceptance. The advanced techniques adopted in the design of buildings, structures, products, gave the opportunity to the interior space elements like ceiling, furniture, windows, doors, etc., not to be rigid, thus allowing for more flexibility space wise, setting wise, beauty wise etc. The different needs and requirements of people, community and country are analyzed which lead to the significant achievement of flexible design and architecture. This paper uniquely analyzes how the flexible architecture comes out to be a solution for prevailing problems in different countries.Keyword-Flexible, Architecture, Adaptive reuse, Tent Structure, Low Cost, Sustainable I. INTRODUCTION The noblest architecture can sometimes do less for us than a siesta or an aspirin… Even if we could spend the rest of our lives in the Villa Rotunda or the Glass House, we could still often be in a bad mood: Alain de Botton, The Architecture of Happiness Architecture is all about creating spaces that triggers emotions and creates a sense of place which may be coined as 'a friendly way of living with nature'. The neural satisfaction for being inhibited to a system and an urge to occupy it lifelong is the outcome of a real great architect. The prevailing aspects of the relationships provided by architecture that stands or exists today are of modern urban, rural and flexibility. Besides, global consumerism and mobility the other factors that have transformed architecture to movable, adaptable, transformable modes are the availability of steels and weldable materials, easily mountable riveted structures, screwable members etc. which help to stabilize system by use of optimized energy and resources from nature. Contemporary architects with their unconventional architecture are trying ...
