What are buildings used for recreation and lounging, near marinas called? Something like a club house but only for private use. Generally owned by very wealthy people with yachts. The words coming to my mind are "lounge" and "outhouse", but I'm thinking of something on a grander scale.


Solution 1:

In the UK the building that houses a yacht club is called the clubhouse, e.g.

Brighton Marina Yacht Club Clubhouse

Note that in the UK, outhouse usually means something like this https://upload.wikimedia.org/wikipedia/commons/b/b9/Amish_Outhouse.jpg
