How to make a set of a space capsule? I am going to make a short film for the 2019 Cinespace contest created by NASA. 
The short is going to take place inside a space capsule. It has to look something like this:



How do you guys suggest I do it? Do I build a set from scratch? If so... how do I construct it? 
Thanks!
This really depends on your budget.

Low Budget:
Find a room which allready looks futuristic with a lot of tech or stuff that looks like buttons and displays. Like in your image, you could make a little bole eye windows with some salad dish, put a screen behind which plays space stuff.

High budget:
Build a little wood cage, also add a little window which shows space and adds natural light.
Then go to home depo and just buy a lot of diffrent knobs and buttons.
