Design Space is tricky to define, because it’s the water we swim in. Mark Rosewater (who probably coined the term) says that design space is roughly how many new cards can be made from a new mechanic. A mechanic that affords a large design space interacts well with the rest of the game and allows them to create a wide variety of new cards. In other words, Design Space defines how many differentiated game elements (cards, weapons, characters, moves, enemies, obstacles, projectiles, etc.) you can create from the base mechanics of your game.
Relative to my 3-filters theory of Depth, Design Space acts almost like a 4th filter, above Possibility Space. Design Space defines which possibility spaces can even be made with the mechanics and attributes you have available to you. Possibility space is all the things that can happen in your games. Design space is all the possible games (or content) that you can make with the mechanics and systems you have chosen. In this way, game designers strive not only to create possibility spaces that are rich with possible game States, but design spaces that will allow them to create elements that enable those possibility spaces to contain a multitude of game states. A more richly detailed character allows for a more richly detailed environment for that character to interact with.
