One trick I used on this house was to sew the window onto the end of a strip - that way I know that section isn't going to be too short.
After sewing the window section on, I trimmed everything and then decided I didn't want quite so much slant to the sides of the house, so I straightened them up a bit. I like how that changes the look of the window - it's not going to be square anymore.
I cut out an oversized roof with steeper sides for this house, but completely forgot to take a picture of it. I then cut out a big rectangle of sky, just like I did for the "normal" house. But I want to keep the angle on the top of this house AND not worry about bias all along the top of the block so I'm going to angle the bottom of the sky so that it matches the house section. I just sliced along here.
I then cut around the roof, just like with the first house. And made a slice for the chimney. But the wonky house needs a funkier chimney, so I used an angled chimney fabric strip AND sewed it to the end of a wider sky strip. After sewing that in, I trimmed it up.
That's what that looks like sewn back together. The chimney is actually subtler than I was expecting - guess I didn't angle it as much as I should/could have. You'll notice that today the smaller sky section was sewn on so that there's extra sky peaking out on top. Just gonna slice that sky off even with the roof.
I've got enough sky and roof that I can move my house section more to the left or the right. Too much to the right might mean I lose a bit of that roof corner, but that would be okay. I could also decide at this stage that this roof is just way too big and could slice an inch or so off the bottom of this top section - that would make it smaller.
