Marshall Space Flight Center Building 4205, the Propulsion Research Development Laboratory, is a relatively new building, having been constructed in 2002-2004.

I received some undated architectural renderings for Building 4205, which I present here.

First, two overall views of the entire building:

The "swooping" section about a third of the way over from the left is the main entrance to the building. As the part of the building with the most visual impact, it received special treatment by the folks making the renderings.

The first image is of the north side of the main entrance; it juts out from the rest of the building, so the rock-textured wall is perpendicular to the main building.

The west side of the main entrance, as one might view it from the street.

This is the view of the actual entrance doors, looking toward the north.

The interior of the grand entrance currently houses a small gallery containing propulsion-related exhibits, including a cut-away RL-10 engine, rocket engine turbopumps, and a cut-away SSME powerhead, although this was not reflected in this rendering.
