I took the notion of shelter at its most literal and basic, the main consideration being the climate: cold in winter, hot in summer. After all, if the climate were perfect, there would not be a need for a shelter at all, maybe a bench under a tree,and perhaps a sign.
A shelter by its nature is sustainable: they consume little energy, use few building materials, and produce no carbon. (The bus would ideally run on propane, fuel cells, hydrogen, hybrid, or power lines overhead — similar to trolleys.)
The shelter is high enough to allow a bus to pull under – a nice thing to have in inclement weather. This gives it also a more gracious proportion in the city scape, aligning with a tree canopy. Material are simple: 1" recycled steel plate, pre-rusted, clearcoat sealed, polycarbonate glazing, graphics. The polycarbonate glazing provides wind protection in winter, with a gap at top to allow hot air to escape in summer. The canopy allows the low winter sun to warm the surfaces, and provides shade from the high summer sun. Lighting is in the paving for ease of maintenance.
The shelter can be easily installed with modular components, and unbolted and relocated as needs require.
An optional “flex” area can be a built-in table and benches, protected by a low wall and hedges. Other options are a bike storage area (with possible steel canopy similar to main shelter), ticketing machine, space for vendors — pushcarts or stalls.
The goal was a simple, attractive no-fuss shelter.
