Ecosystem

21031 Burj Khalifa 73 — Released around the same time as other 2016 Architecture sets; the reviewer considers both Capitol and Buckingham Palace (21029) to be excellent, though prefers highly detailed and accurate models of famous buildings over skylines.

21029 Buckingham Palace 71 — Two excellent sets released at once; both preferred by the reviewer over the earlier skyline sets for their highly detailed and accurate building models.

21010 Robie House — The Capitol set is described as the second-largest box in the Architecture line after Robie House.

Previous large LEGO Architecture sets — It's been a while since LEGO brought out something new of a larger size; this new larger scale is worth doing and the reviewer hopes for more large sets in the future
