The Difference Between Open Space and Defined Space in Outdoor Design

Key Takeaways 

• Defined outdoor spaces feel more comfortable, functional, and inviting than large, undefined areas  

• Retaining walls create level, usable space on sloped properties  

• Seating walls help organize gathering areas and encourage people to stay longer  

• Boundary walls add structure and privacy without fully closing in the space  

• Natural stone walls improve both the appearance and long-term functionality of outdoor living areas  

A large backyard can seem appealing at first glance. More space feels like more possibility. But many homeowners discover something unexpected after living with it: open space alone doesn’t always lead to usable space. 

Without structure or definition, yards can feel exposed, disconnected, or difficult to use comfortably. People stay close to the house instead of spreading out into the landscape. Gathering areas feel temporary instead of intentional. 

That’s where stone walls change the experience. Thoughtfully designed retaining walls, seating walls, and boundary walls help outdoor spaces feel organized, grounded, and easier to enjoy. 

Retaining Walls Create Space Where There Wasn’t Any Before 

Sloped yards often limit how people use their property. Furniture sits unevenly. Gathering areas feel cramped. Water runoff can create erosion or drainage issues. A retaining wall solves these problems by creating level areas that support patios, walkways, fire pit spaces, and outdoor kitchens.  

Instead of forcing the landscape to work around the slope, the wall reshapes the property into usable outdoor rooms. 

Benefits of retaining walls include: 

• Creating flat gathering spaces  

• Improving drainage and erosion control  

• Making movement through the property easier  

This changes both the function and comfort of the yard. 

Seating Walls Give Outdoor Spaces Purpose 

A patio without definition can feel unfinished, even when the materials are high quality. Seating walls help solve that by establishing natural gathering points. They visually anchor the space while also providing practical seating during cookouts, family gatherings, or evenings around a fire feature. 

They guide how people use the space without making it feel rigid. A curved seating wall around a fire pit, for example, naturally encourages conversation and helps people settle into the environment more comfortably. 

Walls Add Structure Without Closing the Space In 

Not every wall is designed for elevation change. Some exist to create a sense of enclosure and balance within the landscape. Boundary walls help outdoor spaces feel protected without cutting them off from the surrounding property. They can frame patios, define entrances, or soften transitions between different outdoor areas. 

This subtle structure makes large outdoor spaces feel calmer and easier to navigate. The result is often less about privacy and more about comfort. 

Defined Spaces Feel Better to Spend Time In 

People tend to use outdoor spaces more often when they feel intentional. 

Defined areas: 

• Make gatherings feel more natural  

• Help people understand where to sit or gather  

• Create visual balance throughout the property  

• Improve flow between patios, walkways, and landscapes  

Natural stone walls also add texture and permanence that blend into the surrounding environment over time. 

Designing Outdoor Spaces That Feel Connected 

Stone walls should work with the landscape, not compete against it. Placement, scale, material choice, and craftsmanship all influence how the finished space feels and functions. 

At Maplehurst Outdoor Living, retaining walls, seating walls, and boundary walls are designed as part of the overall outdoor experience—not just standalone features. 

Because the goal isn’t simply to divide space. It’s to create outdoor environments that feel comfortable, usable, and connected to the way people actually live.
