Using react state changes i did this solution.

First, you have positioned every room at a fixed point. You need to rotate the rooms which means you need to change their positions.

For this, i changed the fixed points in Room components to take it from props.

Example: for room8,

export function Room8({position,...props}) {
  const { nodes, materials } = useGLTF('./models/room8.glb')
  return (
    <group castShadow receiveShadow {...props} dispose={null}>
      <group castShadow receiveShadow position={position} rotation={[Math.PI, 0, Math.PI]}>
    ...your code
    </group>
  </group>
  )
}

do this for all rooms.

Then add those positions as array in your PartOne.js

const positions= useMemo(()=>[
    [0,0,0],
    [-4, -2.7, 0],
    [-0.5, -2.7, 3.6],
    [-7.6, -5.5, 0],
    [-4.5, -5.5, 3.6],
    [-0.4, -5.5, 7.2],
    [-7.6, -8.3, 3.55],
    [-4, -8.3, 7.2]
]);

In PartOne.js

add a state to have your rooms in order.

const [rooms,setRooms]=useState(
    [RoomOne,Room2,Room3,Room4,Room5,Room6,Room7,Room8]
);

add your button and rotate the room array,

<button onClick={()=>{
   let arr=[...rooms];
   arr.unshift(arr.pop())
   console.log("arr::",arr)
   setRooms(arr)
}}>Rotate +1</button>

render the state rooms inside canvas,

<Canvas shadows camera={{ fov:70, position: [0,0,30] }} >
    <Suspense fallback={null}  >
       <ambientLight intensity={0.3} />
       <directionalLight castShadow receiveShadow intensity={2} position={[80,80,80]} />
     {rooms.map((room,roomIndex)=>room({position:positions[roomIndex]}))}
       <ContactShadows />
    </Suspense>
    <OrbitControls enablePan={true} enableZoom={true} enableRotate={true} />
 </Canvas>
