To paraphrase Simon and Garfunkel, you evoke the sounds of silence here and not just the idea of it. The way time itself almost seems to slow and stretch, and the way tiny, insignificant noises acquire a weighty significance, like in this line: "In one of the bathrooms, the occasional drip-drip-drip of a shower head was complemented by the whisper of a breeze-blown curtain at the bedroom window."

The silence here and the way the narrative moves throughout the house also emphasizes the emptiness of the Manor, and I thought for a while it would be about Dick having moved out.
Lyrical is definitely the word, and the writing is so gentle, without any harsh words or sharp, jagged phrases. Everything just...flows. Beautiful.
