en route

The plan shows an enclosed courtyard within a cultural centre (think museum/art gallery). It functions as a circulation space between two wings of the building. It can be approached in both directions.

The existing structure consists of 9 columns supporting a grid of beams at ceiling level. This must remain intact.

The section indicates a height difference of 2000mm between both entrances. This necessitates the inclusion of stairs and a ramp. No lifts are permitted.

It is a further requirement that it is possible to cross from the stairway to the ramp or vice versa on at least one point of the journey.
