Earlier this week, we checked in with the student winners of the American Society of Landscape Architects (ASLA) 2011 awards and found reason to be hopeful about the future of landscape architecture. But what legacy will those students be inheriting? The ASLA has recently doled out 37 awards to professional firms from across the globe, honoring their innovation, design, and sustainability.  The submissions (most of which have been built) range from the systematic redesign of streetscapes and historical residential gardens to large scale estuarine master plans.

Check out the winners after the jump.
