This is a project about small moves recasting big territories. Doubleground is the 2018 NGV Architecture Commission and was located in the sculpture garden of Roy Grounds’ National Gallery of Victoria. It is a response to Gallery’s brief to create a temporary, site-specific work in its sculpture garden over summ­er. As an intervention, the project specifically seeks to challenge the role of the garden. Rather than an object in the garden, it is the landscape that generates interiors and rooms and, by burying, reveals a new kind of architecture. Collage is used as a tool for stitching together a formal memory of the pre-Bellini NGV building or a memory of it blurred by time. Lines in the collage become walls and the walls occasion tectonic folds in the turf plane of the garden, re-formalizing an architectural memory from what was. The project is not about making spaces that are performative but rather spaces that offer invitation, are explored and passed through-spaces for the body: a room, a corridor and a field. Doubleground shows the way in which small scale, low cost, collaborative and multi-disciplinary interventions can create tipping points within an existing landscape condition that comprehensively transform that landscape’s ability to invite, hold and engage visitors.
