Thrushcross Grange is a luxurious place compared to the more rustic Wuthering Heights. There is more opulence and more refinement to Thrushcross, which is reflected in the characters who people each place. A great example is Edgar Linton (Thrushcross) versus Heathcliff (Heights): Edgar is refined and elegant, he governs his passions and emotions and is definitely upper class whereas Heathcliff is rough and inelegant, full of passion which he never represses and is definitely the product of a lower class.
The two homes reflect the people you'll find in each. The problem starts when Cathy denies her heart and opts for the luxury and refinement over the true love and passion.
These ordered pairs more often than not, are pairs of contrast. The most noticeable pair is that of the two houses: Wuthering Heights and Thrushcross Grange. Wuthering Heights has the wild, windy moors and its inhabitants possess the same characteristics. Opposite this are the calm, orderly parks of Thrushcross Grange and its inhabitants. Each household has a male and female with a counterpart at the other. Readers gain insight into these characters not only by observing what they think, say, and do but also by comparing them to their counterparts, noticing how they do not think, speak, and act. Much is learned by recognizing what one is not.
the people at WH are not as sophisticated as those at the Grange. It's almost like the people at WH contaminated the innocent people at the Grange. Catherine married Edgar, and thus entangled him and his family into the mess at WH. The marriage led to Isabella falling for Heathcliff, and this all just snowballs and sets up a number of opportunites for Heathcliff to get his revenge. as for the settings, the grange appears to be more sheltered and luxurious than WH. WH is in the open, exposed to the wind, and it's not described as being as scenic as the grange. that can be used to reflect the characteristics of the people living in the separate locations. the grange folks are more sheltered and innocent than the conniving residents at WH.
Never have two more opposing places existed than Thrusscross Grange and Wuthering Heights. Wuthering Heights is a dwelling characterized by fiery emotions, primal passions, bitter vengeance, and blatant evil. Thrushcross Grange is a peaceful, beautiful abode which epitomizes all that is good and lovely. Emily Bronte includes these two places in the Romantic novel, Wuthering Heights, to create a contrast which furthers the overall theme of good vs. evil.
