Why landscape
One plan for everything outside
Landscaping goes wrong when the pieces are designed separately: planting by one company, irrigation by another, lighting added after the beds are finished. We draw the hardscape plan and the softscape plan together, then design the irrigation and low-voltage lighting into the same drawing. Wire and drip lines go in before the plants do, and nothing has to be dug up to be added later.
On a recent Rancho Palos Verdes front yard, that meant a full landscape plan, custom irrigation zoned to each planting area, and low-voltage path lighting along the new beds, all installed in one sequence. The photos below show it.
From simple to extravagant
Some yards need a drought-tolerant refresh and smart irrigation. Others become full backyard programs with grading, drainage design, retaining walls, kitchen gardens, even a small working vineyard. We design across that whole range, and landscaping tends to give the best return of anything you do outside: plants grow in and look better every year.

What you get
Everything we deliver.
- 01
Yard design & site plan
Conceptual design, planting plan, hardscape plan, irrigation plan. We design for your house, your soil, and the way you actually use the yard.
- 02
Drought-tolerant & California-native planting
Plant palettes that thrive in the South Bay's coastal climate without weekly watering. Sage, manzanita, ceanothus, succulents, native grasses — the look people associate with Manhattan Beach and Palos Verdes.
- 03
Hardscape, paths & patios
Pavers, decomposed granite, concrete, flagstone. Retaining walls for the hillside lots in Palos Verdes and San Pedro. Steps, stairs, and walkways that hold up.
- 04
Drip irrigation & smart controllers
Drip irrigation with Hunter or Rain Bird controllers, weather-based scheduling, rain shutoff. Water bills cut in half is common when we replace old spray systems.
- 05
Outdoor lighting & low-voltage
Path lights, accent uplighting on trees, deck and step lights. Installed by the same crew that handles your home's electrical — one phone number for both.
