The directed landscape is a scale-invariant random directed metric on the plane which sits at the center of the KPZ universality class. In this walk, we introduce a version of the directed landscape with a boundary condition (i.e. in `half-space'). We show that the directed landscape in half-space is the common scaling limit of two KPZ models: exponential last passage percolation and coloured TASEP. Based on joint work with Lingfu Zhang.
