So I made a city in Minecraft. Not just any city, but the city from my novel (in a slightly scaled down version anyway). And I did it all properly, no cheating, no inventory hacking, no map editing. I did it in peaceful, because let's be honest, mobs are annoying if you just want to build. I do have another map I play in Hard mode when I want to do that, but for building projects it's all Peaceful.
It took a LONG time and it's not actually quite finished yet - I've got some farm areas to put in (but I don't have enough seeds and it takes ages to get them), and I still need to furnish the houses with doors, beds, etc. Also I need to add market stalls in the main square. But the place is pretty much built now. It has taken a long time. Allow me to illustrate. This is how the land where I built it looked when I started:

For anyone interested, the seed is "i dunno, something". No speech marks, obviously, though I can't remember if I capitalised the I or not. Possibly not. It does have a comma. You actually spawn a little west of the pain, sometimes southwest. but it's not that far away from the spawn. And there's surface coal near the spawn, if anyone is interested.
So it's a decent sized plain, if you get rid of those two hills in the middle there. It didn't take long to dig through them either - an hour maybe. They're tall but not large, so it wasn't much work. I needed a fairly large flat space, and I wanted to put a river through it and have farms and stuff too. So i made it a bit flatter and cut off that little hill on the right and then decided I needed a little more space than that. Well anyway. Here are some progress shots, taken from the same place:


So yeah I removed the side of a very big hill too. I left a tree standing where it had been to show how much I removed. It filled about 8 double chests, all the cobblestone and dirt I mined. Oh and i kept the tree in the middle of the shot for reference in screenshots.
Imageshack has managed to lose some of my screens so I'll add the next progress shot when i get home and can sort it out. But after levelling the plain I made the river. To do this, I walked the route I wanted the river to take, placing torches as I went. then when it was dark, I used the edge of the torchlight as a guide for the edges of the river, and either dug down or built up the banks, depending on the level I was at, to mark out the edges. Then I dug out the river to a depth of 1, or filled it in where it was deeper than that. This is because of the way water works. Placing water doesn't work the way I want it when you're not placing it on a flat surface. So the whole river is one deep; at some point I'll fix this and dig it deeper in the middle, but for now it looks okay. At the ends, I've basically just stopped it; I plan on taking it further in both directions, but need to do some digging and levelling and it's out of sight around a hill in one direction and beyond viewing distance in the other.
Filling the river with water once it was fully dug didn't take long, because of the way water replicates if there is a source block on two sides. I used this princliple to fill the river in about ten minutes. And it looks good.
Then I started building. I started with the bridge, then planned out the city, starting with the palace and the main square, then the roads, the temple of Reth, and the gates. I didn't plan all of it at this stage, because I didn't know how much space I'd need for the houses and stuff. Anyway, this is the first progress shot after I started building:

I actually built one of the houses first. It's a courtyard house like what there was in ancient Greece. there aren't many windows, but light comes in through a courtyard, onto which most rooms open. More private rooms don't open directly onto the courtyard. It's about privacy, and about separating public from private. I based my city in my novel loosely on the archaic Greeks, so using architecture which wouldn't have been unheard of was part of that.
Also notice in the last photo, birch trees! That was just after the update with birch saplings, and since birch trees come in sizes from 5 to 7 blocks of wood high, it's easier to harvest than normal trees (oaks?) because I don't need to break any leaves or build any dirt towers to get at higher branches.
The next thing I did, after getting to grips with the houses, was the palace. I had quite a strong idea of how this looks, but I didn't have space to fully realise it. The version I've made is a cut down smaller version of the palace, but with the same essence of the layout. It's based around a courtyard, though a much larger one than the houses have (often as small as 2x3). On the right are the stables, on the left the official dining rooms, which open onto the courtyard but have doors into the corridor inside too. Straight ahead from the entrance is the main entrance into the building itself, which opens into a corridor with the doors to the great hall dead ahead, the stairs to the left and the treasury to the right, though more doors. the great hall has three entrances - the main one, the kitchen one, and then also stairs out which go upstairs to the royal quarters. There is also a balcony running along above where the corridor is. Upstairs are the private bedchambers, some of which have a nice view over the courtyard - in my novel, this is where my main character takes rooms. He likes to see what's going on.
Anyway, here's the palace courtyard, from the corner between the stables and the entrance:

With the palace complete, I got to work on the walls, the rest of the houses - split into two groups, the larger, sandstone courtyard houses, and the smaller, wooden houses, some of which have small courtyards - 2x2 or 2x3 - and only two rooms. Some of the smaller houses are just 1 room. After that, i built the temples - the temple of Reth is tall and majestic, loosely based on the Greek temple, but rather than having collonades it's just a rectangular building with buttresses, sorta. There were some temples like this in the archaic era in Greece, but none surviving. The temple of Sune is smaller, with a rounded roof (as much as possible in Minecraft anyway), and it has a basement with a pool of water in it. In the novel, this pool of water becomes significant.
I also added a brothel next door to the temple of Sune, since I had a gap there, and the royal mint between the main gate and the palace. There are a couple of large courtyard houses outside the city, which are farm houses, and some small wooden houses near the gates outside the walls. Finally, I built a little house next to the bridge, with a fence; this is the stables, where those without space to stable their horses in their own homes can leave them when they're in the city. The idea is that wealthy landowners will have a modest town house and a much larger country house, where they spend most of their time; and with city space at a premium, it's easier just to have this sort of facility. Like in Oblivion.
Anyway, photos:


You can see one of the houses outside the city is labelled "Arkin's house". Arkin is one of the man characters in my novel. It's called The General's Secret. He's one of the two generals. The losing one (that's not a spoiler, it happens right at the start).
So yeah, that's that.
I still need to add things like doors and furnishings, finsih off the farms and plant some "olive" farms and "vinyards" (tree farms and sugarcane farms). Someone promised to make me a texture pack, so I can get stuff to look right, and the walls will look better.
More screenshots when I have more to show.
