# Draw an ASCII house

This is a window:

---
| |
---


Let's add some walls |. Put two spaces on either side of it so that the window has plenty of room.

|  ---  |
|  | |  |
|  ---  |


Now let's add a roof and a ceiling. To keep the window in the middle of the room, let's add one more row above it and below it.

---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


Now, just add a roof. Put a slash as far left as possible, and a backslash as far right as possible, and we have this:

/       \
---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


Then move the slash up one and right one. Move the backslash up one and left one:

 /     \
/       \
---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


Repeat until the two slashes meet, then add an asterisk where they meet:

    *
/ \
/   \
/     \
/       \
---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


And you're done! This is a 1x1 house. a 2x2 house would look like this:

        *
/ \
/   \
/     \
/       \
/         \
/           \
/             \
/               \

|  ---  |  ---  |
|  | |  |  | |  |
|  ---  |  ---  |
|       |       |
-----------------


and a 3x2 house:

            *
/ \
/   \
/     \
/       \
/         \
/           \
/             \
/               \
/                 \
/                   \
/                     \
/                       \

# The challenge

You must write a full program that takes two integers, x and y, and prints a house that is X rooms wide and Y rooms tall. Your program should be able to handle houses up to 10x10. IO can be in any reasonable format. Trailing spaces on each line are allowed, and one trailing newline is allowed.

Try it online!

I've improved my vim-golfing skills significantly since I posted this answer, so I decided to go back and write this whole thing from scratch. Saved thirty-three bytes in the process!

Input is assumed to be on two separate lines, so that the buffer looks like this before you start typing:

4


I had a very detailed explanation, but I don't feel like writing it all over again from the beginning... >_< Check out the revision history if you still want to see it.

## Python 3.6 (pre-release), 221210 203 bytes

x,y=eval(input())
w=8*x+1;p='-'*w+'\n'
for v in['*',*[f'/{" "*i}\\'for i in range(1,w-1,2)],p+p.join([''.join(f'{"".join([f"|{(a*3)[:3]:^7}"]*x)}|\n'for a in(*' -','| |',*'- '))]*y)+p]:print(v.center(w))


Reads 2 integers (separated by comma) from stdin, prints the house to stdout.

x, y = eval(input())
w = 8 * x + 1 # total width (in characters)
p = '-' * w + '\n' # floors
for v in [

print(v.center(w))

• Which 3.6.0a0 feature/s does this use? Just f'{name}' string formatting? – cat Mar 2 '16 at 17:49
• @tac: only f-strings, yes – vaultah Mar 2 '16 at 17:50
• How did you install 3.6? I've been eagerly waiting for f-strings, but couldn't figure out how to install it myself (then again, Cygwin support isn't great) – Sp3000 Mar 3 '16 at 12:18
• @Sp3000: I built it from source – vaultah Mar 3 '16 at 12:53

## Python 2, 190 181 bytes

w,h=input();W=w*4
for i in range(~W,h*6+1):print['-'[i%(h*6):]*(W-~W)or['  %s  '%' -|-  - -  -|- '[~i%6::5],'-'*7][i%6<1].join('|'*-~w),' '*~i+['/%*c'%(w*8-~i*2,92),'*'][W<-i]][i<0]


Pretty sure there's much to golf, especially the windows, but here's something for now. Input width and height comma-separated, e.g. 1,2.

Quick and rough explanation:

                *          <--- i = ~W = -w*4 - 1.    <---\
/ \         <--\ i = -W = -w*4             | Preceding spaces

/     \          |                           | the same way
/       \      <--/ i = -1                <---/
/--->    ---------      <--- i = 0

is zero     |  ---  |         |                           | (ditto with |-------|)

Thanks @Neil for helping trim this down!

a=>b=>[(p=(c,d=' ')=>d.repeat(c))(m=4*a)+'*',...[...Array(m)].map((c,i)=>p(--m)+/${p(i*2+1)}\\‌),y=p(8*a+1,'-')].join +p(b, +[x=p(a,'|'+p(7)),w=p(a,'| --- '),p(a,'| | | '),w,x,y].join| )  Call as: F(a)(b) Builds the roof, then assembles the core house with layered string repeats. • When I saw your answer I pondered whether you should have used join|\n  and now I wish I had commented at the time. It would have been a good excuse to add to my partial comment suggesting you use 9*a at some point, which I never submitted because it was too short. – Neil Mar 3 '16 at 0:34 • Your formula 4*a-1 looks incorrect, I think it should be 4*a, this would incidentally save you 4 bytes. – Neil Mar 3 '16 at 0:44 • m-i-1 becomes --m. 9*a-a becomes 8*a. – Neil Mar 3 '16 at 0:46 • Now, you're not actually using any templates in your strings, and you could have done  *\n${[...Array(m)].map(...).join\n}\n  but you can go one better and join the string before and after at the same time: a=>b=>(p=(c,d=' ')=>d.repeat(c),[p(m=4*a)+*,...[...Array(m)].map((c,i)=>p(--m)+'/'+p(i*2+1)+'\\'),y=p(8*a+1,'-')].join\n+p(b,\n+[x=p(a,'| '),w=p(a,'| --- '),p(a,'| | | '),w,x,y].join|\n)) – Neil Mar 3 '16 at 0:48
• Shave off one more byte with /\${p(i*2+1)}\\‌. – Neil Mar 3 '16 at 8:58

• I think you can drop one of the backslashes in the string, i.e. | \-'. – Sp3000 Mar 3 '16 at 10:32
• @Sp3000 That does work, thanks. I guess \- doesn't mean anything as an escape sequence, so the \- is just parsed as 2 characters. Then of course - has a special meaning to tr, so we need the string ' \-' for the windows to escape the - (mapping C-> space, B->- and A->- as there are no more characters left.) For the floors, we have only the string '-' and in this case tr seems happy to interpret it just as a literal rather than a special character, assigning C=B=A = '-' All in all it was a tricky thing to get working. I'm sure there's more golfing to do, will edit later. – Level River St Mar 3 '16 at 11:04

• Nice, couple of general tips that apply here: you can save a handful of characters by taking a closer look at some of your for-loops (s="" can be put inside the for(j) loop (consider j-->0 for the condition as well, and i++<h in the last loop), i=0 can be moved out of the for loop into the declaration saving a byte. You can also save a byte by reusing assigned empty strings (once m is assigned, you can assign o=m saving the "". Replace also takes strings, so you can use your q instead of ' ', and there is no need for the space after the > when declaring r. Small things ;) – VisualMelon Mar 7 '16 at 23:00
• Sometimes it's the small things that make the difference. Thanks :D – DW.com Mar 8 '16 at 12:42

# VBA, 284 bytes

Function H(W,S)
L=vbLf:H=Space(4*W)&"*"&L
For R=1 To 4*W:H=H &Space(4*W-R)&"/"&Space(2*R-1)&"\"&L:Next
J=".":P=String(W,J)&"|"&L
D=String(8*W+1,"-")&L
E=Replace(P,J,"|       ")
F=Replace(P,J,"|  ---  ")
H=H &Replace(String(S,J),J,D &E &F &Replace(P,J,"|  | |  ")&F &E)&D
End Function


The Replace function is a neat tool for making multiple copies in a way that the String function unfortunately doesn't want to.

Invoke for best effect in the Immediate window of the VBA editor: ?H(8,8) for example.
