DIY stacked wood fireplace facade -- I actually really love this idea even if you don't have a fireplace to begin with. It'd be so simple to zazz-up a brick or stone wall with a faux fireplace to create a gorgeous feature wall.
This wall table is one of my favourites of all time. It is so clever designed, and the finish is over the top. When this table is folded up it looks totally like a picture, and when folded down the image hides below the table!
