Creating building assets - what is your workflow?

Hi, i’m new to the forums page and i wanted to know what is the best way to tackle the project of making and texturing personal building assets in both blender an substance painter/ designer?

Here’s my first set of assets i created within 4 days just as an exercise but now i’m more interested in making more building assets for my cyberpunk scenes!
