This house in the Phu Nhuan District of TP. Hồ Chí Minh is akin to House 6 in its experimentation.
Unlike House 6, it is fairly well resolved -- the diagonals are a consistent part of the composition, and relate to the rectalinear frame very well. I like the way it looks like this house is holding up the new house next door.
It is good to see Vietnamese architects trying out ideas like this, particularly when they are fairly successful at resolving the compositional issues. But most ideas like this don't serve well as a prototype for further exploration. This is definitely a "one-off" design.
