From competition website:
Erotic and Architecture are not two words often used together. That does not mean they should not be, so we welcome you to change your usual perception of space and look around yourself to find buildings, constructions, bridges and other places and spaces that arose erotic associations.
By Erotic Architecture we don’t mean only obvious suggestive forms resembling human body parts. We would like to see work presenting combinations of spatial qualities, materials, rhythms and atmospheres witch in their unique combination could be considered erotic.
Photos with human interaction are allowed nevertheless the architecture should be playing primary role in the composition.
As we all have subjective associations, this is first competition where we allow our readers to vote on their favourite photograph and pick the “readers favourite”. The invited judges will pick the other winner.
We understand that the line between erotic and pornographic material may be thin to some therefore before photograph is published we reserve the right to decide on each entry separately.
This is an international architectural competition and it is open for all.
