Hello and welcome to my new video, How to Draw a City Street View in 1-Point Perspective,

step by step, in this video I'm going to show you one way to draw a

city in one-point perspective and to do that we're going to start with the

horizon line, which is a horizontal line which will be towards the bottom of the page

and that will be the line which will be between the sky and land and on

that we draw a dot in the center and then from that we draw an angle line

going towards the right and then another angle line, a diagonal line going towards the left,

now these two lines will be the road which are going towards the dot which is

now from this vanishing point in the center of the horizontal line

we need another line coming up towards the left

which will be the height of some of the buildings on the left hand side of

and then we'll need another line going towards the right which will be the

height of most of the tops of the buildings on the right hand side of

so we have a basic structure for the street already in place, now we'll put a

vertical line, starting on the diagonal, going down and then from that vertical

line right touch the diagonal line will draw a right angle line towards the right and

this will be the start of the side of one of the nearby buildings in our

street and then add another vertical line and then we have the side rectangle

of the nearest building, if I draw yet another vertical line again from the

diagonal, that will give me the length of the building and then I can draw a

triangle on the nearest side of the building and that will give me the pitch

next I need to work out the angle here that goes to the vanishing point, I won't

draw the line all the way along, just to some extent and sort of imagine it going

to the vanishing point,  and then I'll copy the diagonal line of the pitch of the roof

for the further line of the pitch of the roof and therefore I got my first basic building,

next to go into another building which can be behind this first

so the vertical line is slightly to the left of the far side vertical line of

then I read it across and with the horizontal line and then I put another

pitched roof for the first few buildings,

I don't know why but they are going to have pitched roofs, and I'm sort of

visualizing the diagonal line going towards vertical without drawing it

and then I need to work out here if there's going to be any part of the side

of the roof that I'm going to see, so it's gonna be a really small thin sliver

of the roof, but I'll put it in any way and I can work that out again by reading

to the vanishing point, now on the left hand side I need some buildings here so

I'll put a vertical line quite close to the left hand side and then I'll put

another vertical line and that this will be the facade of the first building that

now this budding divided into equal stripes and all of these will be like

floors of the building which will go, if they were continuous lines, to the

and then I also use this technique to create the tops of the doors or maybe

the bottoms of the windows or tops of the windows on the right hand side,

just by putting some lines and diagonal lines, which again will always go towards

the vanishing point, if they were to continue from where they are,

so, next I will put a little door in here for the nearest building on the right

hand side and then on the left-hand side I'll sort of echo that and put a door

structure here, reading across from the vanishing point to find out where the

top of the door goes, the angle of the top of the door, and it's just up to me

where the vertical line will go, and then I'm going to extend the vertical line on

the left-hand side to make this building taller,

indeed I'll make the building to the left of it taller, because that will make

it seem nearer and then I'm going to place another building, again not right

next to the building of stripes, but a little gap in between it and then the

far wall of it as well and these vertical lines always need to be

the left and right hand sides your paper, now this building, I'm going to make it a

so I put a little roof in here, like a pitch roof triangle and then I can read

across from the tops of these to the left

that sort of 90 degree angles, so that they're parallel to the horizontal line

that we did earlier on, and then that will create the top of the build and

then, I am imagining this as some sort of church,

I might put a window in here so I'm working out from the other diagonal

lines I have  already got, and knowing where the vanishing point is, I'm working out the

top and the bottom of the window first, because I know that the vertical lines

I'll put in some small markings within the window, just to show that it's an

area which has some complexity to it, and then below the window I need some sort

of door or entranceway to this building and, I've made it quite large here,

I'll probably put in in a doorway or some stairs in here,

just to break it down into a more reasonable size

quite often churches you have a big door and within the big door there is a smaller door,

anyway I'm just making up these buildings, as sort of interesting shapes and here

I'm going to divide this building up in to vertical lines and I think this will

help with the structure of this building,

I think I need a few more buildings, so again I'm going to do a vertical line

which isn't touching the previous line and then I just top and tail it with a

right angle going towards the right, then that will be the side of the building,

and then I'll work out where the top of this new building go and how far back it

will go, I don't go too near to the horizontal line and the vanishing point

because otherwise it will look like an endless building, so you can stop these buildings quite short

by making the vertical lines quite close to each other, particularly as they get

nearer and nearer to the vanishing point,

and here I will  just put in some windows, it's quite a good idea when you're doing

windows, as you do the vertical lines on them, that you just read them down so

that the windows on the buildings that you're producing are symmetrical and in

it will just look, make it look more like a building, so here on the left I feel

that I need a taller building, so I might just increase the size of some

and here the line this that I've just put in would be going more or less to
