Walk a building massing

Sketch the volume where it’ll go. Walk the perimeter with a colleague.

Sketch a proposed building’s massing at true scale on the actual lot. Walk the perimeter, feel the setbacks, see the shadow against the neighbour’s roof line. Decisions about height and footprint that used to need a physical mockup — a strip mall infill, a house addition, a rezoning study, a stage set flat — happen with a real-scale reference.
