If there's one word that sums up our most popular projects of 2015, it's "diversity." The list features architects ranging from old favorites such as SANAA, Diller Scofidio + Renfro and OMA down to newer names like Sculp[IT] and Tropical Space; it also includes everything from museums to multi-family housing and spa retreats to chapels - along with the usual smattering of private residences. Interestingly, this year's list also shows the symbiosis between great architecture and great photography, with no less than 4 projects also appearing in our most bookmarked images from this year's World Photo Day. But despite their diversity, there's one thing all of these 20 projects have in common: great architecture. So settle in, relax and read on - here's our 20 most popular projects of 2015.

5,000 3D cameras to help preserve the architecture of a country torn by war; A team of Latin American architects that moved into Venezuela’s most dangerous neighborhoods in order to design and build with the community; A legendary architect who understood architecture’s relationship to the transformation of technology -- and whose projects have celebrated technology across a trajectory of multiple decades. These are the projects, initiatives and people who have proven to be leaders in 2015.

ArchDaily’s editorial team wanted to recognize these projects for their commitment to promoting practices in architecture that serve many, in all corners of the globe -- from Bolivia to London, from Chicago to Venice, from public spaces in favelas to projected drone-ports in Africa. These are the stories that have inspired us in 2015, and whose influence we hope to continue to see into 2016.
