Final answer:
The original plan for the area across from the White House in Washington, D.C. included a grand national avenue, now known as Pennsylvania Avenue, and a public garden space.
Step-by-step explanation:
Originally, directly across from the White House in Washington, D.C., there was supposed to be a grand national avenue extending west. However, the actual development differed, and over time various other structures have taken their place.
The plan for Washington, D.C., as envisioned by Pierre Charles L'Enfant, included a grand avenue, which is now Pennsylvania Avenue, and a public garden space, but not specific buildings like the ones mentioned above. The nature of the question seems to refer to the earlier urban design plans for the capital.
