Hives are built off various unique Hive Rooms. Each of these rooms are relatively easy to identify, but all serve their own unique purpose to benefit the hive in one way or another. Some have multiple attached mechanics whilst others may only hold one.
When burning down a hive room, it will eventually be rendered destroyed/unusable once the hive claim on it is no longer visible. Using this, players can destroy key parts of a hive prior to fighting a hive from a range using a flamethrower or other incendiary weapons.
For now, here is a list of the hive rooms and what they do.
Royal Chamber.

The Royal Chamber acts as the primary central room of a hive. Within this room will exist the Queen or Empress with about a dozen or so ovomorphs that she’s laid. This chamber itself never truly is “destroyed” unless the hive and its queen are too.
When a hive is first beginning, this will be the first ever hive room created and developed alongside being the largest at 3x3 chunks.
Jelly Vat Storage.

The Jelly Vat Storage is a smaller room, similar to the ovomorph storage room that contains roughly 8 Jelly Vats. When this room is created, it allows a hive to begin holding “Jelly Reserves.” This coming from a hive that produces more than enough Royal Jelly. Using this, players can have a way to farm royal jelly by waiting for the vats to fill up.
Jelly Vats will also hold scourge jelly, a red version of royal jelly with much more potent abilities and ones that lead to more.. Aggressive evolutions in xenomorphs.
Ovomorph Storage.

The Ovomorph Storage room is a room similar to the Jelly Vat Storage room. However, two vents line the left and right side of the room where xenomorphs will place excess ovomorphs in. Through this, the hive is able to produce more ovomorphs as they have more storage to actually hold them.
Upon destroying this room, it may make defeating hives easier overtime due to them loosing additional storage for ovomorphs and therefore a slower rate of producing xenomorphs through hosts. However be warned, these vents due to the close proximity can be used by defenders to remove any intruders swiftly.
