Landscape Architecture is the creation of outdoor environments that complement architecture and harmonize with nature. Use of architectural materials, details, and proportions, in combination with regionally appropriate plant materials, are used as elements in the creation of functional and harmonious outdoor environments. Terrain is sculpted to create topographies that enhance architecture and spatial experience. Walls, trees, boulders and screens further articulate proportions. The sound, flow and lambent light of water move through passages and lie quiet in outdoor rooms. Compression and expansion create a linked sequence of spatial experience. Plant material colors and textures provide counterpoint to architecture. Light and shadow alternate to create rhythm and variety. Mystery, surprise, and whimsy, engage, beckon and direct. Architecture is extended into the landscape and landscape is blended into architecture.
