I created a couple of buildings to play Monsterpocalypse with my son and friends and also for places like this.
Default 5.5 x 5.5cm base size.
Print with SLA or DLP for max detail.
I print it with a Anycubic Photon 50ym layer hight with 15 seconds exposure time each. Best way is to print it in black, color spray it with black basic color, add white color as light effect (fogging) and finish it with high glossy varnish. I added sample pics, renderd and photos of the finish colored building. You can also spend more time and color it in detail.
