I have been a fan of the Architecture series since it started. This, so far, is the most unique set that they have come up with. This set is so special because unlike other sets, you can see inside the actual structure and see the furniture and fireplace (the apex of the interior).
On to the building process. Overall the pieces were not the most diverse, there were just a lot of them. If you look at the picture, the entire roof is made up of 1 x 1 smooth bricks. The bottom line is that the monotony of the roof, veranda, and stairs may be a downer to less experienced LEGO fans.
As a whole the set is absolutely beautiful. The lack of diversity of pieces only matters if you want to eventually scrap it for parts. That said, if you are a true fan of the LEGO Architecture series, then you should have no thought of using the pieces other than for the original set.
