The best Los Angeles landscape design-build companies do more than create attractive yards; they translate a homeowner’s goals, architecture, site conditions, and budget into an outdoor environment that can actually be built and maintained. For residential projects, that means coordinating planting, patios, hardscape, grading, drainage, irrigation, lighting, privacy, outdoor kitchens, pools, and other features rather than designing each element in isolation.
That distinction matters in Los Angeles. A flat backyard in the Valley presents different challenges from a compact Westside lot, a coastal property in the South Bay, or a steep hillside home in the Santa Monica Mountains. Sun exposure, soil, drainage, access, privacy, mature vegetation, and local permitting can all influence the final design.
The companies below represent different approaches to residential landscape design-build. Some are particularly suited to comprehensive outdoor-living renovations, while others lean more toward landscape architecture, environmentally conscious gardens, or complex construction. The ranking is a practical editorial shortlist, not a claim that one contractor is the right choice for every property.
Pacific Outdoor Living
Pacific Outdoor Living is an established Greater Los Angeles design-build company focused on complete outdoor environments. Its residential capabilities include landscape design, hardscape, patios, pools and spas, outdoor kitchens, fire features, lighting, and other outdoor-living improvements.
One of its strongest advantages is the ability to approach a large backyard as one project. That becomes valuable when a homeowner is considering several interconnected features. A pool deck, for example, needs to relate to the patio, planting, drainage, outdoor kitchen, circulation routes, and lighting.
The company’s process combines design, construction, and project management. Its website states that it has operated since 1999 and completed more than 10,000 projects, although homeowners should still evaluate the firm’s experience with projects comparable to their own rather than relying on overall project volume.
For homeowners planning a substantial outdoor transformation, Pacific Outdoor Living is a strong company to include in the initial comparison.
Trilling Landscape Design + Build
Trilling Landscape Design + Build takes a full-service approach to residential landscapes throughout Los Angeles and surrounding communities. Its work encompasses landscape design, planting, hardscape, patios, outdoor kitchens, pools, spas, fire and water features, lighting, and related outdoor-living elements.
The firm’s approach is notable for bringing design and construction together. Its team includes landscape designers, landscape architects, project managers, and construction crews, allowing the company to take projects from concept through installation.
That can be particularly useful for homeowners who want the landscape to complement the architecture rather than simply surround it. The company specifically discusses modern homes, hillside properties, remodels, privacy requirements, and indoor-outdoor connections.
Trilling can be a good fit when the homeowner wants a highly coordinated outdoor environment and expects the landscape to play a significant architectural role.
KRM Landscapes
KRM Landscapes specializes in custom residential landscape design-build projects. Its approach is deliberately site-specific, with the company describing each client and landscape as unique and emphasizing collaboration around individual needs and terrain.
That philosophy becomes particularly relevant in Los Angeles because site conditions can vary dramatically within a relatively small geographic area. A property may require solutions for steep grades, wildfire exposure, water conservation, privacy, or difficult circulation.
KRM’s work is also positioned around different lifestyle objectives. A homeowner might need a family-friendly backyard, a space for entertaining, a pool environment, a meditation garden, or a landscape designed with water conservation and wildfire risk in mind.
Rather than selecting KRM solely for a particular visual style, homeowners with unusual terrain or a highly customized brief should consider whether its site-responsive design-build approach matches their needs.
Gregory Davis & Associates
Gregory Davis & Associates is a Westside Los Angeles landscape design-build firm with more than 30 years of experience according to the company. Its residential services include landscape design and construction, hardscape and softscape installation, retaining walls, walkways, fountains, fences, and other outdoor features.
The firm places considerable emphasis on its design process and uses 3D modeling to help clients visualize proposed outdoor spaces before construction.
That can solve a common problem with landscape projects: homeowners often understand individual materials but have difficulty imagining how the finished space will feel at full scale. A 3D model can help reveal proportion, circulation, privacy, sightlines, and the relationship between structures and planting before those decisions become physical.
For Westside homeowners who want a design-intensive process backed by construction capabilities, Gregory Davis & Associates is worth considering.
Eco Landscape Design & Build
Eco Landscape Design & Build focuses on custom residential landscapes in Los Angeles and the San Fernando Valley, with particular attention to modern landscapes, drought-tolerant gardens, outdoor living, and Southern California’s climate.
Its design-build model allows the design team and installation crew to work together rather than separating the design from construction. The company emphasizes designing with the builder’s input and building with the designer’s guidance.
That distinction is useful when the landscape includes details that depend heavily on installation quality. A sophisticated planting composition, custom hardscape, or carefully integrated outdoor-living area can lose much of its intended character if construction does not follow the design closely.
Eco Landscape may be especially suitable for homeowners seeking a contemporary residential landscape that balances appearance, usability, and water-conscious planting.
RAD Landscape
RAD Landscape is a Los Angeles-based landscape design and build studio working on projects ranging from private gardens and courtyards to larger residential estates and public environments.
Its approach begins with the site. The company identifies factors such as topography, drainage, solar exposure, wind, existing vegetation, views, and the relationship between the home and the land as fundamental inputs to the design.
That is an important way to evaluate a landscape professional. Instead of starting with a list of features—“I want a patio, lawn, fire pit, and pool”—a site-first designer asks what the property can support and how people should move through and use it.
RAD can therefore be an appealing option for homeowners with architecturally distinctive properties or those who want the landscape to feel like a natural extension of the house.
Design Scapes Inc.
Design Scapes Inc. provides residential landscape design-build services throughout West Los Angeles and the South Bay, with service areas including Santa Monica, Brentwood, Pacific Palisades, Beverly Hills, Bel Air, Manhattan Beach, Hermosa Beach, Redondo Beach, and nearby communities.
The company’s focus is on bringing landscape design and construction together under one designer-led process. Its residential work can encompass planting, privacy screening, irrigation, lighting, patios, hardscape, pergolas, outdoor kitchens, retaining walls, and broader backyard remodeling.
One of the more useful aspects of its approach is the emphasis on real site conditions. Design Scapes says that slope, drainage, access, material transitions, and installation sequencing are considered during planning rather than being treated as construction problems later.
That matters particularly on Westside and South Bay properties, where narrow lots, coastal conditions, elevation changes, and limited construction access can affect what is practical.
The company says it has more than a decade of design-build experience and identifies certifications relating to pavers, retaining walls, irrigation, and outdoor structures. It also states that its projects are handled by an in-house crew and that it provides scheduled warranty check-ups.
For homeowners who want a single team to coordinate landscape, hardscape, privacy, irrigation, lighting, and outdoor living, Design Scapes Inc. is a relevant choice to evaluate.
Olmos Landscape
Olmos Landscape has been serving Los Angeles and the San Fernando Valley since 1975 and presents itself as a full-service residential landscape design-build company.
Its services cover landscape design, pavers, patios, pergolas, outdoor kitchens, fire features, planting, lighting, irrigation, and maintenance.
Longevity alone does not establish that a contractor is the right choice for a particular project, but it can be useful when assessing companies in a field where project coordination and installation experience matter. Olmos also emphasizes a single-team approach from initial concept through construction.
Its broad service range makes it suitable for homeowners who want to renovate several portions of the property at once. Instead of installing a patio first and figuring out planting, irrigation, and lighting afterward, those components can be considered within the same landscape plan.
Lani Construction
Lani Construction is a broader Los Angeles residential contractor that also provides landscape and hardscape services. Its outdoor capabilities include custom landscape design, 3D renderings, planting, irrigation, lighting, grading, patios, walkways, retaining walls, and outdoor kitchens.
That broader construction background can be advantageous when a landscape project overlaps with other residential improvements.
Consider a property where the homeowner is remodeling the house while also changing the backyard. The exterior may need to coordinate with new doors, elevations, utility work, structural changes, or an expanded entertaining area. Having a contractor experienced in both residential construction and landscape-related work can simplify some of those relationships.
Lani is therefore worth considering when the landscape project is part of a larger residential renovation rather than a completely standalone garden installation.
Landscape Development, Inc.
Landscape Development, Inc. is a substantially larger landscape organization with capabilities spanning landscape architecture, construction, maintenance, arbor care, and environmental services.
Its landscape architecture division works on design development, construction documentation, and construction administration, while its construction operation handles large-scale landscape projects. The company works across residential-adjacent development as well as multifamily, commercial, public, and master-planned environments.
That scale makes it different from the smaller residential specialists on this list.
For an individual homeowner, a large organization is not automatically better. However, it can become relevant when a project involves a substantial property, complex landscape architecture, extensive construction coordination, or development-scale requirements.
Homeowners should determine whether the company’s project scale and service model are appropriate for their individual residential needs before moving forward.
What does “design-build” actually mean?
The term is often used loosely.
A true landscape design-build process generally means the design and construction functions are coordinated through the same company rather than the homeowner hiring one designer and then finding a separate contractor to interpret the plans.
That can reduce handoff problems.
For example, suppose the designer specifies a large-format stone patio but the site has restricted access and a difficult grade. A contractor involved during design can identify those constraints before the plan is finalized and recommend a material or installation method that is easier to execute.
The trade-off is that the homeowner may have less separation between designer and builder. If independent design oversight is important to you, hiring a landscape architect separately and obtaining competitive construction bids may be preferable.
Neither approach is inherently superior.
What should a residential landscape design include?
A meaningful landscape plan should answer practical questions, not simply show where plants will go.
It should establish how people enter and move through the property, where they sit, how outdoor rooms relate to one another, how privacy is created, where water moves during rain, and how irrigation will serve the planting.
Hardscape should be considered at the same time. Patios, paths, steps, retaining walls, decks, fences, pergolas, and outdoor kitchens affect grading and circulation.
Plant selection should then respond to those physical conditions. A plant that looks excellent at a nursery may perform poorly in a shaded courtyard, exposed hillside, narrow planting bed, or salt-influenced coastal environment.
The strongest plans are therefore not collections of attractive features. They are systems.
Los Angeles site conditions deserve special attention
A residential landscape in Los Angeles can involve considerably more technical planning than the finished photographs suggest.
Hillsides can introduce grading, retaining, drainage, erosion, access, and structural considerations.
Coastal properties can expose materials and plants to salt air, wind, intense sunlight, and other environmental stresses.
Dense urban lots may have limited access for equipment and materials while placing greater emphasis on privacy and efficient use of space.
Mature properties may contain established trees, existing walls, old irrigation systems, or drainage infrastructure that should be evaluated before demolition.
This is why homeowners should ask prospective contractors to explain what they see during the site assessment. Their questions can be as revealing as their answers.
How much should you prioritize design versus construction?
It depends on the project.
For a straightforward lawn replacement or planting renovation, construction execution may be the primary concern.
For a complete backyard remodel, design becomes much more important because dozens of decisions interact. Patio dimensions influence furniture placement. Furniture placement affects circulation. Circulation affects planting beds and pathways. Those elements affect irrigation and lighting. Grading affects drainage and retaining requirements.
In other words, the more interconnected the project, the more valuable an integrated design process becomes.
Common mistakes homeowners make
One mistake is choosing a contractor based almost entirely on photographs. Images show the final appearance but rarely reveal how drainage was solved, what happened beneath the patio, how utilities were routed, or how the landscape will behave after several growing seasons.
Another is requesting individual features without first establishing a site plan. A homeowner may ask for a fire pit, outdoor kitchen, pool, lawn, and pergola without realizing that fitting all five comfortably may compromise circulation or planting.
Budgeting is another frequent problem. Homeowners should ask for a detailed scope and understand what is included in demolition, excavation, grading, drainage, utilities, permits, materials, installation, planting, cleanup, and warranty support.
Finally, maintenance is often treated as an afterthought. A landscape should be designed for the level of care the homeowner is realistically willing to provide.
How to compare landscape design-build companies
Start by defining the project rather than asking several contractors for a generic estimate.
Decide whether you need a planting renovation, hardscape improvement, complete backyard remodel, outdoor-living project, or whole-property landscape.
Then look for companies with demonstrated experience in the same type of work.
Ask about:
- Design responsibilities and deliverables
- Site analysis and measurements
- Drainage and grading
- Irrigation design
- Plant selection and long-term maintenance
- Hardscape construction
- Permit and inspection coordination
- Subcontractors and in-house crews
- Construction scheduling
- Payment milestones
- Change-order procedures
- Workmanship warranties
- Post-installation support
Most importantly, ask what happens when the original plan encounters a real-world condition that was not visible during the initial consultation.
That answer tells you a great deal about how the company actually operates.
Choosing the right company for your property
A useful way to narrow this list is to match the contractor to the complexity of the project.
If you want a large-scale outdoor-living transformation, prioritize companies with experience coordinating multiple construction disciplines.
If you have a hillside or technically difficult property, put grading, drainage, retaining, access, and site analysis ahead of cosmetic style.
If you own a modern or architecturally distinctive home, look for evidence that the landscape responds to the building’s geometry, materials, sightlines, and indoor-outdoor connections.
If your priority is water-conscious residential landscaping, investigate the company’s experience with climate-appropriate planting and efficient irrigation rather than relying on the phrase “drought tolerant.”
If you are renovating both house and landscape, consider whether a broader residential design-build contractor would simplify coordination.
And if the landscape itself is the central architectural feature of the property, an independent landscape architecture-led process may provide the design control you want.
The most reliable selection process is to obtain a clear site assessment, compare equivalent scopes, inspect comparable completed work, verify licensing and insurance, and understand who is accountable for construction. A landscape can be visually impressive and still be poorly planned; conversely, a restrained design can perform exceptionally well when its grading, drainage, planting, materials, and circulation have been resolved properly.
For a Los Angeles residential project, choose the company that can explain those decisions clearly—and can demonstrate that its design process survives the transition from drawing to actual ground conditions.
