English to Chinese Social Sciences Real Estate housing

正在翻译一个德国庄园地产的销售信息，在介绍庄园主楼和单独套房时给出了一串详细的features，其中一条（见第三条）提到这个“open plan ground floor”：

• Main dwelling with 3 Bedrooms 3 Bathrooms
• Master suite with dressing room and bathroom with whirlpool tub
• 2 distinct living /drawing room areas in an open plan ground floor layout
• Dedicated office area
• Large dining room

living /drawing room 应该是起居/休息室
ground floor 看起来似乎是一楼，但 open plan ground floor 这几个字连在一起不知如何理解和翻译比较合适。
