Types of Jobs That Could Require a Landscape Architect & Cost
Using creativity and structure, landscape architects can take an average backyard and turn it into an aesthetic yet functional space. From patios to outdoor kitchens, they make sure the design fits the customers property and style. Landscape architects can also improve the resale value of any home and increase usable square footage by incorporating the DeFeo Materials line of products.

Designing Outdoor Living Spaces
Outdoor living spaces are meant to be an extension of any home. They’re built with comfort, flow and regular use in mind. Architects design a space by considering shade, seating, and paths that are both practical and aesthetic.
Creating Retaining Walls and Erosion Control
Retaining walls are a necessity for sloped yards with runoff issues. Architects plan these walls to be attractive yet useful, protecting against erosion while also giving the yard structure. Natural stone or manufactured blocks can be used for the wall design. Depending on the project scale costs can range anywhere from $3,000 to $15,000.
Adding Water Features and Ponds
From a simple koi pond to an elaborate waterfall, water features bring dimension to any landscape project. Architects design water features not only to fit a vision but to also function well with the landscape’s drainage. Small projects such as simple fountains generally cost a couple thousand dollars whereas larger, more elaborate projects cost upwards of $15,000.
Planning Full Property Layouts
Planning full property layouts before breaking ground is where landscape architects come in. They create a master plan including walkways, lighting, plant placement, patios and water management. These larger scale projects usually start at $10,000 and can reach $50,000 or more for complex builds.
Factors That Influence Project Costs
Size and Scope of the Project
The size of any renovation space plays a huge role in cost. A simple patio design or a small fountain will be far less expensive than a complete backyard makeover. Some architects charge hourly while others charge per project. Completing a backyard renovation in phases can spread out costs.
Materials and Stone Selection
Material choice and stone selection can have a big impact on renovation budgets. Wood, concrete and stone all have select availability and different price points. Many architects recommend New England River Rock for its durability and timeless look. When choosing materials, it is also important to consider its longevity.
Site Preparation and Installation
Before construction begins, there may be some prep work. Good architects plan for clearing or grading to ensure proper drainage and soil preparation. While prep adds to the overall budget, poor prep leads to future repair costs.
