Here's a breakdown of Bruno's descriptions:
* Big: The house is large, with many rooms and hallways.
* Dull: The house is decorated in a bland and monotonous style, with little color or personality.
* Lifeless: Bruno feels like the house is lacking in warmth and vibrancy, and that it is devoid of life.
* Boring: Bruno finds the house to be uninteresting and lacking in excitement.
* Confining: He feels trapped and restricted by the size and formality of the house, which stands in stark contrast to the freedom he experienced at his old home.
Bruno's descriptions reflect his feelings of discontent and isolation within the house, which symbolizes the stifling and oppressive nature of his new life in Berlin. He longs for the open spaces and familiar comfort of his previous home.
