The problem with Scaling and Rotating

• The house shifts position relative to the origin. Not what you would expect when rotating or scaling an object.
  
  

More natural solution

• Move house to origin, then scale, (and/or rotate), then move house back to original position

• Matrices performed in a sequence can be composed into a single matrix
