There are six permanent additions in Blue Prince that can add helpful upgrades to the Mt. Holly estate. Each one gives you a benefit — like extra steps or additional rooms — but they all require work to unlock.
Our Blue Prince guide will show you how to unlock all six permanent additions, help you solve any puzzles they require, and tell you what you get for each.
Update (April 17): Added two more permanent additions.

There are six permanent additions in Blue Prince. You’ll find them listed in your pause menu below your items.
They are (in the order the game uses):
- West Gate Path — unlocks the Outer Room
- Gemstone Cavern — starts every day with two gems
- Apple Orchard — adds 20 steps
- Blackbridge Grotto — allows you to use one offline terminal per day
- Blue Tents — adds hidden blue memos to each blue room drafted on the 8th rank
- Satellite Dish — unblocks inbound electronic mail and communications and adds new experimental data packets to the Laboratory
Read on to see how to unlock each of these permanent additions, or click the links in the list above to go directly to the one you’re interested in.
How to unlock the West Gate Path in Blue Prince

Unlocking the West Gate Path requires you to draft both the Utility Closet and the Garage on the same day. In the Utility Closet, turn the power on to the Garage, and then you can open the Garage door and head outside.
Take a left and you’ll find your way back to the front of the house where you can (permanently) unlock the West Gate. Heading west from there will bring you to the Outer Room where you can draft a new set of rooms like the Trading Post and the Shelter.

Speaking of the Utility Closet, you’ll need that to unlock the Gemstone Cavern. You’ll find hints for the V.A.C. Indicator puzzle in the Mail Room and the Office’s computer’s emails.
Solving that puzzle gets you access to a switch that turns on the Gemstone Cavern benefit of two gems at the start of each day. (You don’t have to visit the Gemstone Cavern over by your campsite on the east side of the house.)
How to unlock the Apple Orchard in Blue Prince

You can find the Apple Orchard behind your campsite on the east side of the house, but the gate is locked with a four-digit code. To find it, you’ll need to draft the Utility Closet (again) and the Darkroom. You’ll also need to have a Magnifying Glass.
Use the Utility Closet to turn the power back on in the Darkroom. Inside, use the Magnifying Glass on the pictures inside to find the code to the Orchard gate. Once it’s unlocked, you’ll get 20 extra steps per day.
How to unlock the Blackbridge Grotto in Blue Prince

Unlocking the Blackbridge Grotto takes a bit of work and a lot of luck. You’ll need to draft the Boiler Room and then connect the Laboratory to it either directly or via rooms with ducts along the ceiling. Once you do, you’ll have to solve both Laboratory puzzles.
To get the benefit of the Grotto, you’ll also need the terminal password. With that, you can choose the “login to network” option at any computer and use the remote terminal access option to get at a computer you haven’t drafted yet.
How to unlock Blue Tents in Blue Prince

To unlock Blue Tents, you’ll first need to reach Room 46 to unlock the Mount Holly Giftshop, which is only available after you’ve seen Blue Prince’s credits. Next, you’ll need to earn eight trophies by completing various challenges like solving 40 dartboard puzzles or winning 40 Parlor games.
With those said and done, you can finally get your hands on the Blue Tents permanent addition by purchasing the souvenir from the Mount Holly Giftshop for a measly, uhhh… 400 coins. The permanent addition definitely has a hefty cost, but will assist you in finding information for post-credits puzzles.
How to unlock the Satellite Dish in Blue Prince

The Satellite Dish can be unlocked after solving the puzzles found in the book “A New Clue,” which can be purchased from the Bookshop. The puzzle require you to find a major key, find other books around the estate, and reveal the hidden message, “Turn scorched sundial base.”
The sundial can be found in the Apple Orchard, but you’ll first need to scorch the base with a Burning Glass (Magnifying Glass and Metal Detector combination). Turn the scorched base to reveal three microchip sockets, which you’ll need to bring from the Blackbridge Grotto or find in their hidden locations. Once the microchips have been slotted in, the Satellite Dish will rise up from behind the hills and establish a connection to the outside world.
