Landscape Architecture
The design of outdoor spaces, from plazas and parks to site grading and planting.
Quick Answer
Landscape architecture is the design and planning of outdoor spaces and the land around buildings. Landscape architects shape grading, drainage, planting, paving, site furnishings, and public space. They combine ecology, engineering, and design to make sites usable, attractive, and resilient, from small courtyards to parks and campuses.
The Full Picture
Landscape architecture treats the site as a designed system. The profession covers site layout, grading and drainage, planting design, hardscape such as paving and walls, site lighting and furnishings, and the relationship between buildings and the outdoors. It operates at many scales, from a private courtyard to regional planning.
Landscape architects work closely with civil engineers and architects. Civil engineers typically lead utilities, stormwater infrastructure, and roadway design, while landscape architects shape the overall site experience, plantings, and surface treatments. Many landscape architects also design green infrastructure such as bioswales, rain gardens, and green roofs that manage stormwater naturally.
The profession is regulated. Most U.S. states license landscape architects, and the American Society of Landscape Architects (ASLA) is the main professional association. Their drawings include grading and planting plans, irrigation layouts, paving and wall details, and planting schedules.
For project teams, landscape is a common source of late changes and cost pressure because it is built at the end, when budgets are tight. It also touches permitting, through requirements for tree preservation, stormwater, and accessibility, so it benefits from early coordination with the civil and architectural design.
Real Examples
Common Misconceptions
People assume: Landscape architecture is just choosing plants.
Actually: Planting is one part. The work also covers grading, drainage, circulation, hardscape, site systems, and public space design.
People assume: Landscape architects and landscape contractors do the same job.
Actually: Landscape architects design and prepare construction documents. Landscape contractors install and maintain what was designed.
Frequently Asked Questions
What does a landscape architect do?
They design outdoor spaces, including grading, planting, paving, site features, and green infrastructure, and prepare drawings and specifications for construction.
How is landscape architecture different from landscape design?
Landscape architecture is a licensed profession in most states with a broader technical scope. The term landscape design is used more loosely, often for residential planting and garden work.
What is hardscape versus softscape?
Hardscape refers to non-living site elements such as paving, walls, and steps. Softscape refers to living elements such as trees, shrubs, and lawn.
Do landscape architects work on stormwater?
Yes. They often design green stormwater features and coordinate with civil engineers, who usually handle the engineered drainage and utility systems.
