Interesting that you should be writing about love in terms of a house.

Nice alliteration in the second line to convey the persona's pain, except that I hate that there should be a comma between BUNCHING and BROKEN. You should remove it.

Just to be sure I understand your work, I think the couplet at the end summarises that, once the love is gone from the house, no attempts at sprucing the place up can make it the same as before because of the simple fact that the love is gone. So while there's a physical warmth, the chill of love's loss felt only by the persona still preponderates.

On the whole, quite nicely done, except that that the fourth line seems forced.

Not an avid sonnet reader myself, I don't have anything to say about the piece being a sonnet. However, I did like what it contained - especially the analogy of the house being like your lost love. That was genius. You used amazing words that complimented your piece very nicely.
