Where To Find All Floorplans In Blue Prince

So, you're looking for the Found Floorplans in Blue Prince? While most rooms in the game can be drafted by default--with a bit of luck and prayers to the RNG gods--there are other areas with blueprints that you must obtain first. Doing so adds them to your drafting pool, and they have a chance to appear when you draw rooms. In any case, please be forewarned that this article contains spoilers.

All Found Floorplans in Blue Prince - Floorplan locations guide

There are eight Found Floorplans that we've discovered so far. These include the Planetarium, Conservatory, Closed Exhibit, Mechanarium, Lost and Found, Treasure Trove, Tunnel, and Throne Room.

We've organized our guide to focus first on the blueprints that you can find in the manor, followed by those that are outside and underneath the estate.

• Location: Observatory - Use the upper and lower dials of the telescope so you can bring it closer to the ledge above. This allows you to open a hidden compartment.
• Effect: If you call it a day inside the Planetarium, you gain +2 stars.
• Tip: The Planetarium has a clue telling you that a new constellation appears when you have 50 stars. This grants you another method of rerolling/redrawing rooms.

• Location: Study - You need to open the Study safe box. Once you've unlocked it, you can grab this Blue Prince Floorplan.
• Effect: The doors in the Closed Exhibit are security-locked.
• Tip: You can complete the Closed Exhibit Puzzle to acquire the Red Paper Crown, which is another unique reroll/redraw mechanic.

• Location: Underground - At the giant Rotating Gear section, rotate the dial so you can reach the niche with the map and the blueprint.
• Effect: Has one door for each gear-type room in your house.
• Tip: You can solve the Mechanarium Puzzle to receive a Sanctum Key.

• Location: Underground (Basement) - In the same spot where you found the Mechanarium floorplan, you'll see a full map of the Underground. If you have a Magnifying Glass, you'll notice a barely visible scribble saying that there's a buried floorplan in the Basement. Make your way there and bring a Shovel with you. Dig at the spot near the curvature of the passage (as shown in the image above).
• Effect: The Lost and Found room always has two rare items. However, whenever you enter it, you also lose a random item in your inventory.
• Tip: You lose one item in your inventory whenever you enter the Lost and Found, so make sure you avoid visiting it unless absolutely necessary. Alternatively, you can draft it as an outer room if Blessing of the Monk is active and you end your day while inside it. This lets you grab two rare items at the start of your run when you still have nothing in your inventory. It's actually how we found the last Vault Key that we needed.

• Location: Underground (Red Door) - You can reach this place by activating the Red Doors via the Boiler Room. Rotate the giant gear again so you can cross the gap at the top section.
• Effect: +5 gold for each time you've drafted the Treasure Trove.
• Tip: Maybe you can try what we did with the Lost and Found room. Hmm...

• Location: The Grounds (Campsite) - The clues come from the music sheets found all over the house. Bring a Shovel and dig at the center of the white trees to claim this Blue Prince Floorplan.
• Effect: Adjust the rarity of floorplans in your house.
• Tip: The Conservatory is one of the best rooms to draft in the game. It ensures that you can set how common or rare certain rooms appear in the drawing pool.

• Location: The Grounds (Tunnel) - Head down the stone steps in front of the manor and you should see a dark tunnel. If you have something that can light torches, then you can pick up this item.
• Effect: You always draw another Tunnel when you're inside this room.
• Tip: This is actually a great way to beeline straight for the farther sections of the manor, though the doors still require keys.

• Location: Blackbridge Grotto - You must complete the Laboratory Puzzle to gain access to Blackbridge Grotto. Then, you need to find all three Microchips so you can place them in the pedestal's indentations.
• Effect: "Reclaim the Crown!"
• Tip: You can draft this and grab a Sanctum Key as well.

That does it for our guide on the locations of all Found Floorplans in Blue Prince. As you can see, some of these have unique items that are integral to post-campaign progression. You can learn more about these in our Sanctum Keys guide.
