Tents or a Grand Ballroom

A Back-of-the-Envelope Look at the Costs of State Dinners

Do We Need a Ballroom?

Although the idea of paving over the Rose Garden troubles me, this proposal deserves careful consideration. Such discussions typically begin with back-of-the-envelope calculations, which I had my newly upgraded GPT prepare.

I expected the numbers would reveal an obvious answer, but instead, they present compelling arguments both for and against the project. What do you think?

Current reality:

Over the last decade, the U.S. has hosted ~1–2 state dinners a year (some years none, some years up to 4).
Big-tent events on the White House grounds run ~$300k–$700k each (inflation-adjusted from documented costs).
At that pace, taxpayers see ~$0.5M–$1.4M a year in state dinner hosting costs.

Proposed Grand Ballroom:

Ballroom the size of two football fields (~115,200 sq ft), construction value ~$200M.
Annual operating & ownership costs (excluding added security):
Energy + maintenance + janitorial: ~$0.9M–$1.7M/year
Long-term capital renewal (1.5–3% of construction value): ~$3M–$6M/year
Total: ~$3.9M–$7.7M/year — regardless of usage.

Quick comparison (annual):

Option	Events/Year	Cost/Event	Annual Total	Ongoing Cost to Taxpayers
Tents	~1–2	$300k–$700k	$0.5M–$1.4M	Only when used
Grand Ballroom	Usage may vary	N/A	$3.9M–$7.7M	Every year, empty or not
