Ecosystem

21031 Burj Khalifa — 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 — 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

Owners strongly praise the Capitol's detailed architecture, engaging build, and striking shelf presence, but several express disappointment that only the front facade is modeled, leaving the back half essentially cut off.
