Baubotanik – a German term combining ‘build’ and ‘botany’ – is an emerging architectural approach that uses living trees as building material. It integrates architecture, landscape, and structural design to create living structures, raising new questions for contemporary architectural practice.

But what can you actually build with it? What forms can it take? And what are the potentials - and limitations - of designing with a material that grows, adapts, and evolves over time?

These questions form the starting point for The Growing Library. Set in the tropical urban context of Yogyakarta, the project proposes a public library that grows together with a tree, gradually evolving from an urban park into a living architectural structure. Conceived as a place for knowledge exchange, the library extends beyond a conventional building to include outdoor spaces, living systems, and ongoing ecological processes as core parts of its collection.

At the heart of the design is the Ficus benghalensis, whose aerial roots are trained and shaped to form spatial and structural elements. As they thicken over time, the roots intertwine with bamboo to form a hybrid structure, merging living growth and constructed elements into a single evolving architectural system.
