Landscape Design & Build in Westchester

Westchester landscape is post-war ranch landscape. Flat 6,500-9,000sf lots in a consistent grid, single-story 1950s-to-1970s ranch homes, mature trees from the original tract plantings still in the soil, and a tech-buyer client base that wants drought-spec, MWELO-compliant, smart-controller-driven design with bid line items they can read. The LAX corridor drives some onshore wind and salt aerosol, less than Westchester gets than Westchester Beach but enough to push the palette toward salt-tolerant species. We have been designing in 90045 since 2016 and pulling our own permits as the CSLB-licensed GC since 2023. Real cost band: $40K-$210K depending on hardscape scope and mature plant material. We tell you on the first walk what palette will read right against your ranch.

What a Westchester landscape design and build actually costs in 2026

Off real invoices closed in the last 18 months in Kentwood, North Kentwood, Osage, Westport Heights, and Loyola Village: $40K-$78K for a focused front-yard refresh with drought-tolerant planting, a permeable hardscape strip, and a basic drip-irrigation conversion, $78K-$145K when the scope adds a designed rear garden with custom-poured concrete, integrated low-voltage lighting, a small water feature, and mature specimen trees, and $145K-$210K when the build includes a full hardscape program with a fire pit, custom planters, a built-in barbecue, mature 36-inch or 48-inch box olives or sycamores, and full irrigation integration with the home smart system. Soft costs (design, MWELO documentation) typically add 7-11 percent.

We do not hide the line items. If the client wants the irrigation controller integrated with a Home Assistant or Control4 system, that adds 1.5-3K in controller upgrade and integration design. We put that line in the bid before you sign. About 50 percent of Westchester tech-buyer clients want smart-controller integration.

Off our bid by more than 10 percent? We walk through the plant list by container size and grower, the hardscape spec by finish, the irrigation by zone, and the soft costs. About 65 percent of clients off a competing bid stay because the breakdown clarifies what they are paying for.

Ranch-compatible palette and what grows in 90045

Post-war Westchester ranches read best with a mid-century-compatible palette: mature olives, citrus, lavender or rosemary hedges, decomposed-granite paths, low ornamental grasses, and architectural specimens like Mexican fan palm, mature olive, or coastal live oak. We avoid anything that fights the architecture: no tropical-heavy plantings, no formal English-garden symmetry, no Mediterranean villa overstatement.

The LAX corridor delivers enough onshore wind and salt that we push the palette toward salt-tolerant: Westringia, Teucrium, Phlomis on the ornamental side, succulents like Aeonium and Agave for accent, and California natives like Toyon and Coyote Mint that hold up to dry summers and occasional salt. Standard inland-LA palette burns out at the edges over 3-5 years in Westchester.

MWELO compliance applies to any new landscape over 500sf. We file MWELO as part of the design package, spec a weather-based smart controller, and limit turf to under 25 percent of landscape area. LADWP turf-replacement rebates can offset 4-12K on a typical Westchester front yard. We file the rebate paperwork as part of the project.

Smart-controller integration and tech-buyer landscape spec

Westchester is heavy with engineers from SpaceX, Boeing, and LMU. The tech-buyer client base wants the landscape integrated: smart irrigation controller tied to home automation, low-voltage lighting on scenes that match interior lighting, soil-moisture sensors on the controller for weather-adaptive scheduling, and a controller dashboard that shows zone-by-zone runtime, water budget, and weather forecast. We spec Hunter Hydrawise, Rachio, or Hydropoint depending on the home-automation integration. We tie into Control4, Crestron, Lutron, or Home Assistant per the existing home stack.

The smart-controller upgrade over a standard timer runs 1.5-3K. Most tech-buyer clients take it. The water savings runs 15-30 percent versus a basic timer, the landscape performs better because watering adapts to actual conditions, and the dashboard gives the kind of visibility the client base expects.

Why the architect and the GC being the same phone call matters in Westchester landscape

On a normal landscape job, the designer draws, a landscape contractor bids, the homeowner manages the conflict. In Westchester, where the irrigation has to integrate with the home automation, where the lighting design has to coordinate with the home electrical, where the tech-buyer client wants engineering-grade bid line items, that two-party model creates 30-60 days of delay per revision cycle. We have been the architectural design firm since 2016 and the CSLB-licensed GC since 2023.

200+ LA builds in the file, including LAX-corridor and South Bay landscape work in Westchester, Playa del Rey, and El Segundo. We know what LADBS will permit and what palette will read right against your ranch.
