One more dome question
- Hi all,
Thank you to all of you who have provided such valuable information about
domes and lecture halls. The technical data provided by Philip Groce was
especially cool. The opinions expressed did not generally vary a whole
I don't know how many 30 and 40 foot domes (of either technology) are out
there, but I have been asked to follow up with one more question--until
they think of something else. How many square feet does a 30 or 40 foot
dome (the space the planetarium occupies) take up? i'm not sure how much
this will vary, but I can imagine the variables (computer cool room, chair
storage, etc) that might impact the answer.

What they were really asking for was the overall "footprint" of a dome if you were to include the theater, projection gallery, entrance/exit vestibules, and outer walls. Is that what you're looking for?
I've worked in two 40-ft dome planetariums in the past and with the above criteria, I would guess at something like 2300 sq-ft if the outer walls are circular (with entrance/exit vestibules of about 100 sq ft each), 2800 sq-ft if set inside a square footprint. That's also with a generous amount of projection gallery space.
Just thought I'd offer a SWAG...

- I agree with Mr. Murray. If you are building a new space, every foot counts. A few years back, the estimate here in Iowa was $215/sq. ft. That was an over-all planning cost. A square room behind the dome will show more footage, but costs less than a round room. You have to weigh that against the visual impact of the exterior.
If you pursue this question with the group, I'll follow. If not, I'd luv to be a fly-on-the-wall and see how it goes.
