21st Century Manifesto

ARCHITECTURE FOLLOWS NATURE

Biomimicry in Architecture

An Architecture Manifesto Biomimicry is a way of learning from nature.

CONTENTS

PLACING ARCHITECTURE AT THE HEART OF A BIOINSPIRED FUTURE.

It is a manifesto to a 21st century model, as well as a call for a shift.

‘From architect as singular author to architect as multiple authors.’

‘From architecture as buildings to architecture as the designed and built environment.’

and biomimetic future will bring more sustainable solutions to the design table and promote a shift from the industrial age to humankind’s ecological age.

It is biomimicry, a highly interdisciplinary field involving the understanding of biological functions, structures, and principles. While engineers often mimic nature’s technology to design innovative new products, architects can benefit from this kind of approach to build a new world of sustainable beauty as well.

Either ‘biomimetics,’ ‘bionics’, or ‘biomimicry,’ all imply the process of copying, imitating, and learning from biology. It is a general consensus among the world’s biologists that biomimicry is a practice that learns from and emulates nature’s time-tested patterns and strategies to solve human design challenges.

further two dimensions to the mimicry exist. The design may be biomimetic in terms of what it looks like (form) and what it is able to do (function).

Throughout architectural history and practice, nature is used mainly as an aesthetic sourcebook and architects have mainly taken inspiration from it solely for building forms. Looking to nature for design inspiration has historically been standard practice, from Corinthian columns on Greek temples to Santiago Calatrava’s
