邸宅

1. Origins, structure, and basic meaning

• Structure: 邸宅 is read as ていたく and is a noun for a large, distinguished private residence or estate.
• Basic usage: Use 邸宅が資料館として公開される for a converted use and 舞台は邸宅です for a story setting.

2. Common pitfalls and similar expressions

• More substantial than an ordinary house
  • It suits a prominent old mansion or forest-surrounded estate rather than serving as a general word for any home.
• Current use and narrative setting
  • One residence is now open as a museum, while another provides the location in which a mystery novel unfolds.
