how to build mini model of globe theatre?

Answer 1

Depending on how mini and how accurate, you could start with a cardboard oatmeal box, wrap it with paper, and draw the outside on that. The inside would consist of the roof of the stage and of the boxes.
If you need to be bigger and more accurate, then it would be be best to build it from flat card stock and tag board which is cut and scored to make the "8 sided oval" in at least two sections both so you can get in to build it and to show it off.
Check reproductions of the Globe in San Diego, Midland Texas, and the Folger library in Washington DC.
Wiki as usual has a lot of details and links to reproductions

Answer 2

Wow.

Well, the first thing to do is to get copies of those old books that had conjectural reconstructions of the Globe. I'm sorry that I'm drawing a blank on the titles or authors except for "Shakespeare's Globe Theatre".

Also look at the opening scenes of Olivier's movie version of Henry V.

And maybe do a web search for the actual reconstruction of the Globe that's gone up in London.

Now, once you know what you're building, choose your materials. Legos might work...cardboard is easy to manipulate--but if you're expected to do a high-class job of it, you'll need to go to model railroad shops or hobby stores to find materials for miniatures, doll houses, etc.

Note that the first Globe had a thatch roof that caught fire during Henry VIII and burnt the house down (no one injured!), and the King's Men rebuilt it, but the second Globe had a tile roof. So mind which Globe you're modeling :-)
