If you're gonna sculpt it, and if those buildings are supposed to be brick-built, I would:
1. Bring that basemesh into Zbrush and just use it as a guide and as your mortar object and not much more.
2. Sculpt five or six unique house bricks, and then literally build the wall with those bricks, rotating them and deforming them each slightly. Set the bricks deep into your basemesh It wont take that long.
3. Build the corners as a bricklayer builds corners. Pic related.
4. For the mortar, add a bunch of subdiv levels to your original basemesh (turn off smoothing to preserve edges) and just lightly sculpt and perturb the surface so it's not so even.
5. Export all this as your highpoly, bake it onto your low-poly.

Voila - good looking corners. Job done.
