How to Build a Parapet around a Building in Near shadings?

[MayersSolar]

Hi there, 

I’m struggling to model a parapet around my Near Shadings building in PVsyst. The parapet is 0.3 m wide and runs along the roof edges.

Is there a recommended way to create this?

I tried adding a 0.3 m-high wall around the building edges, but that feels a bit rudimentary. Is there a more efficient tool or feature for this?

Thanks in advance!
