It’s more of an overall artistic style than one particular architectural style. But, strictly in terms of the buildings, I see three or so architectural styles. The building on the left has major mid century modern vibes, especially the horizontal lines and oval shapes. On the right, they are a little more traditional, rectangular, city buildings that were common before the 50s, the staircase is a little odd though. The Cybersex Arcade is the odd one and it’s probably considered Novelty Architecture since it’s made to look like something else. Of course, this is all based on US architectural styles.
