Floating buildings on Venus. What shapes are credible?

Venus is being paraterraformed with floating cities. Mechanical machines collect material from the surface and send it floating at an altitude of about 50 Km where conditions are more Earth-like. Here the material is assembled into building.

The "city" is not in one piece. Each building has its own floating mechanism independent of the others. The city is ring-shaped with buildings moving in a circular motion around an empty center.

Some buoyancy is provided by the internal atmosphere which is less dense than the venusian atmosphere. However I want them to use other systems as well, in particular wind. I was thinking in particular of the Vindskip concept (The video is short and gives an idea of how it works).

What shape/machinery can I give to the buildings to have them harness wind power for flotation?

EDIT: Maneuvering is available for the buildings, and some minor propulsion systems can be considered too
