A quadrangle is a shared space that is enclosed in the centre of a group of buildings that back onto one another--a communal courtyard for activities and a resource for all those who use the buildings that surround it. Similarly, our aim is to create a centre that provides a shared community resource space that is flexible in how it can be used by community members and organizations--a shared space for building belonging across our differences, sharing resources, and honouring our strengths and experiences. The name also tips its hat to the historical significance of the triangle as a symbol of sexual diversity while at the same time acknowledging that our communities include sexual and gender diversity, and that the two are not reducible to the same thing.
