  Buildings are beautiful mathematical objects tying a variety of subjects in
algebra and geometry together in a very direct sense. They form a natural
bridge to visualising more complex principles in group theory. As such they
provide an opportunity to talk about the inner workings of mathematics to a
broader audience, but the visualisations could also serve as a didactic tool in
teaching group and building theory, and we believe they can even inspire future
research.
  We present an algorithmic method to visualise these geometric objects. The
main accomplishment is the use of existing theory to produce three dimensional,
interactive models of buildings associated to groups with a $BN$-pair. The
final product, an interactive web application called The Buildings Gallery, can
be found at https://buildings.gallery \citep{Bekker2020}.
