Maquette

Start
At the very beginning, we turn around and go around the building. There will be a red sphere inside the gazebo, take it and run towards the dome.
There will be a red crystal to the left of the locked gate. We touch it with our sphere and the gate will open.
Red House
We go with our sphere to the building with a red barrier at the entrance, it is located behind the dome.
We go inside and throw the red sphere on the floor.
We go further around the room, go out into the backyard and go up to the second floor.
There we activate the switch and release the blue crystal.
We pick him up and take him out to the backyard where we leave him on the ground.
We return to the room, take the red sphere and go to the layout.
Blue house
We leave the red sphere on the floor outside the dome and approach the miniature.
We take a mini-version of our sphere and take it to the blue building model. We find a slope with a red crystal on the outside of this building.
We put our mini sphere there, it rolls down and rests against the blue barrier.
We take the blue mini-crystal in the courtyard of the red building on the model and go with it to the blue building in the ordinary world.
We pass through the first barrier and approach the second so that it disappears. Thus the red sphere falls inside.
We throw the blue crystal, we won’t need it anymore, take the red sphere and go into the room behind the red barrier.
We watch a cutscene about how good Michael and Kenzie are together.
We open the door using the lever on the wall and first take out the red sphere and place it on the ground outside the dome, and then the green crystal and also place it on the ground outside the dome.
Green house
We go to the dome to the miniature and take the red mini-fera, carry it to the model of the green building and place it on the second floor balcony (on the green barrier).
Let's go and pick up the green mini-crystal, approach it very close to the miniature of the green building so that the red sphere falls inside.
Then we run to the green building in the standard world. As soon as we get inside the building, we need to throw the green mini-crystal out into the street through the grate in the window on the left.
We raise the red sphere and go into the darkness. We watch a flashback about Michael and Kenzie's dream of their home.
After the cutscene, we find ourselves in the house and see a key in the room.
We throw the sphere, take the key and move further around the room into the room with the owl. We turn the key so that it goes through the window and throw it out onto the street.
We return to the red sphere, pick it up and exit through the door on the right by pulling the lever.
We throw the red sphere in the yard, pick up the green crystal and go to the layout.
Yellow house
We pick up the mini-key on the floor near the green house model and take it to the yellow house model, where we open the door with it.
We go to the model of the green building and pick up the red mini-sphere in the courtyard and carry it to the model of the yellow house.
There will be a round hole in the side wall of the yellow house, perfect for our sphere. So we throw it there.
We take the green crystal and run to the yellow house in the standard world.
We go into the yellow building, take the red sphere and go into the next room, where we watch the next cut-scene.
Afterwards we open the door using the lever and go along the bridge to the gear.
Big world
We are not in a hurry to take the gear, because... we see that the road to the dome is closed.
We take the red sphere, holding it in our hands and find a destroyed section of the railing on the bridge.
We jump from the bridge onto the fallen column and then jump over the fence and find ourselves in the enlarged world.
At this stage we will be given an achievement Breakout / Breakthrough , if you have not received it earlier.
In the enlarged world, we run to the crystal on the left and activate it, as at the beginning of the chapter.
*at this stage I recommend not throwing away the red sphere, we need it to get Crew Creatures / Flock of little animals
And so we turn around and run back with the red sphere.
You can go upstairs in 2 ways:
1 - right at the end of the table, go into the niche and on the left you will see a lever that will call the elevator
2 - where we jumped over the wall in the corner there is also an elevator
Overall, to finish the chapter we now need to take the gear and place it in the hole at the back of the yellow building on the layout.

But I recommend returning inside the yellow building with the red sphere, taking the green crystal and returning to the enlarged world with it.
Approach the enlarged copy of the green building and go inside the doghouse.
Here they will give us a trophy Crew Creatures / A flock of little animals .
