How to say "mansion" in Japanese

• 邸宅ていたくJLPT N1approx.Common
  nounCovers 'mansion' as a large, impressive house or residence, typically one belonging to a wealthy family. This is a natural choice when describing someone's grand home in neutral prose.
  彼女かのじょはちょっとした邸宅ていたくに住すんでいる。↗

  She lives in quite a big mansion.
• 屋敷やしきJLPT N1approx.Common
  nounMatches 'mansion' in the sense of a residence together with its estate, grounds or premises. Use it when the land and buildings around the house are part of what you mean, as in describing a lord's estate.
  彼かれはいなかの屋敷やしきに住すんでいる。↗

  He lives on his country estate.
• 大家たいかCommon
  nounGlossed as 'mansion; large house', but as a way to say 'mansion' it is marginal; in ordinary use the word's core meaning lies elsewhere, so it is seldom the word you want for an English 'mansion'.

For a grand residence use 邸宅 (or 屋敷 when you mean the estate and its grounds), while 大家 is the older 'large house' word and is usually not what you want for 'mansion'.
