I strongly second One Plan's idea about looking for another architect. If this one is not motivated, all the fame in the world is not going to help. An alternative approach to finding an architect is to find some good contractors who have built things you like. Ask them for architects' names. Make sure they work in your price range. In the meantime, you can find out from your local building department what the set back and height restrictions are. Are you required to build parking areas or garage space, what kind of airspace restrictions do you have for neighbors' views and sunlight, that kind of thing. Often this stuff is on city websites or handouts at the office.

Or if you could attach a floor plan as a jpeg file you might get some general advice on layout ideas.

Sorry but I don't understand your pictures. You are talking about 2 bathrooms but we see only one floor plan. Is the 1.52M x 2.24M the 5 x 8 bathroom in your dilemma title. If so, can we see the floor plan of the 5 x 9 bathroom? Is the space with a small rectangle in the middle the extra 5.5 x 4.9 ft space you mentioned in your dilemma? Also 1.52M x 2.24M is in reality 5'0" x 7'4". This is 8 in. less. It can make a big difference on how to place fixtures in a bathroom.
