Safdie Habitat 67 study

Is ExtrudeSurfaceAlongCurve available in Grasshopper?

I would like to able to extrude a typical composite wall section (with various layers of different thickness) along the outer line of a floorplan. Of course I have not figured out how to create a typical composite wall section that will always be perpendicular to this line yet.

I am planning starting some kind of Safdie Habitat 67 study with Grasshopper. Parametric modeling usually focus on surfaces and blobs, but can be used to create other things as well.

Basically what I need to do is:

1) A system of rectangles that defines the bottom outline of a habitable unit. [easy]

2) How to convert this bottom outline into a box with a composite wall, and slab system and with windows and stuff. [should i try to create a boolean system from this outline? or a system with extrusions along the rectangle?]

3) A system that generates the staircases and ramps. [basically extrusion along the lines that defines the corridors and staircases]

hmmmmm...
