Unusual floor plans

Penthouses in Chicago Floor Plans | ... Spired: Condo tower's creative shape leads to some unusual floor plans:

It doesn't have a round living room but I love this floor plan!!!

Original house plan was designed to look over a natural lake in the Ozarks. Round gardens and patios relieve the square wall of the main level, however, if that’s not enough, the landing above is beautifully sculpted with delicate curves. The great room is part of the kitchen with the bar having seating on both sides; one seating area behind the couch. Another bar is more of a showpiece, framing the opening into the kitchen from the foyer. The view of the big screen is shared by everyone.

Wallace Neff (1895–1982) may be best known for the Spanish Colonial Revival homes he designed for Hollywood stars including Judy Garland, Groucho Marx and Douglas Fairbanks Jr., but Neff considered his most significant contribution to the field of architecture — his legacy — to be his Airform bubble houses.

Me and my wife have been dreaming up and boiling down ideas for an eventual house build we want to do. Is this something that can be done in cob or balecob?
