Thanks Phflack. I couldn't really do any more work with the tiles and the roof because of the zoning laws in Diggy's city rp :/
@Fionnbhar What do you mean by developing? Do you want me to build some nice buildings on them so it will up up street expectations? What I mean is, settling a zone.
To do this, you must first build a building of some sort in an almost empty area.
After its done, depending on it's type, buildings will appear of the same building type. Like Small commerce buildings will appear if you build a small shop, medium commerce buildings will appear if you build a medium store, and large commerce buildings will appear if you create a huge supermarket! If you look around EcoTek, you will see another office building in progress as well. Street appeal is also looking up.
So if that area continues to be being bought out by big business owners, it will eventually become a business district. Same goes for if you build some nice building on a poor street, the street will eventually bump up to the same expectations your building had! This is straight from the mouth of a popular business owner in Diggy's city rp, it's very strategic, and works in real life as well as it does in his rp. Hope it helps you understand a bit more about city development!
