Conejo Valley

Landscape Design in the Conejo Valley

Landscape design for Conejo Valley homes in Thousand Oaks, Westlake Village, Agoura Hills and Lake Sherwood, and in the Las Virgenes communities beside them. We plan the planting around the oaks, the open-space edge and your association's review, together with the irrigation, drainage and hardscape it depends on, and our own crews build it.

Service options

A Mediterranean-style outdoor space with warm paving, architectural planting and layered garden details

Mediterranean Landscapes

Best for Spanish Colonial, Tuscan, Mission Revival and other stucco-and-tile homes, and anyone who wants a shaded courtyard built for outdoor entertaining.

  • Warm plaster walls and terracotta roof tile set the palette
  • Wood-beamed pergolas and columns create shaded gathering space
  • Quiet fountains and wall features add sound without excess
  • Olive, lavender, rosemary and cypress become low-water once established
  • Handcrafted stonework and travertine patios stay cool underfoot

On your property A natural fit for the Conejo Valley: the palette shares the oaks' tolerance for dry summers, and the Mediterranean and Spanish homes of Westlake Village and North Ranch already speak its language. Keep the irrigated beds outside any oak's root zone, where summer water does harm.

How we work

  1. Bare dirt and worn lawn along the side of a house before construction Before

    Site analysis and the oaks

    We map sun and shade, drainage, slope and soil, and locate every protected oak with its root zone before a line is drawn. On a lot near open space we confirm the fire hazard zone and any fuel-modification requirements at the same visit.

  2. Designer and clients reviewing 3D property renderings together at a design consultation meeting Design

    Design and style selection

    Your designer lays out the garden with the hardscape and shade it depends on and presents it in plan and 3D, in whichever style suits the house: Mediterranean, English Garden, Traditional, Modern, Drought-Tolerant, Japanese Zen or Small-Space.

  3. A landscape design plant specification sheet listing botanical and common names, sizes, and quantities alongside photos of each specified plant Selection

    Plant selection and specification

    Natives and Mediterranean plants chosen for each bed's exposure, the oaks and the fire zone, sized for maturity rather than the nursery pot, and listed on one specification sheet your association can review.

  4. Pacific Outdoor Living crew members preparing rebar and concrete forms during site construction Installation

    Soil, irrigation and planting

    Grading, soil preparation and drip irrigation zoned by exposure and kept off the oaks entirely, then planting, with new trees staked for autumn wind.

  5. A stream running between granite boulders, edged with flax and flowering groundcover Established

    Establishment and care

    First-season watering, mulching and pruning, with care instructions so the garden is rooted in before its first Santa Ana season and its first dry summer.

Key decisions

Things worth knowing before a first consultation.

  • Oak root zones

    In Thousand Oaks, grading, trenching, paving and pruning inside a protected oak's zone generally need a permit. Beyond the paperwork, an oak wants a dry trunk in summer, no regrading under its canopy and no lawn or thirsty beds beneath it.

  • The open-space edge

    Lots that back onto open space plan for fire first. The first several feet around the house stay free of combustible material, planting nearby is low, irrigated and lower-resin, and the fuller garden sits further out. The 2018 Woolsey Fire is why this is a design question here, not a formality.

  • Santa Ana wind

    The valley funnels wind every autumn. Trees are chosen and staked for the worst week of the year, and screens and trellis get footings sized for gusts rather than for an average afternoon.

  • Association review

    North Ranch, Lang Ranch, Dos Vientos, the Westlake lake community and Lake Sherwood all review exterior work, sometimes including planting near shared frontage. The planting plan is drawn to the standard your association expects.

  • Marine air and inland heat

    Marine air over the Conejo Grade keeps summers milder than in the San Fernando Valley, but south-facing slopes and lots further inland still bake. Plant choice and irrigation zoning follow each bed's exposure, not one palette for the whole yard.

  • Slopes and drainage

    Hillside lots in Agoura Hills, North Ranch and around the lakes need grading, drainage and irrigation planned together, with smart controllers to manage water across varied terrain.

  • Septic fields

    Many Lake Sherwood properties rely on septic systems rather than a sewer connection. Planting, irrigation and hardscape are placed with the septic field's location in mind rather than over it.

  • Integration with hardscape

    Planting should soften patios, steps and walls, not fight them, and leave room for a mature canopy without roots lifting the paving.

Investment and timeline

No quote written off a photograph can account for what your property is like.

What shapes the investment

  • Landscape style and plant palette
  • Size of the planting area and the size of plants specified
  • Grading, soil preparation and any retaining on a slope
  • Irrigation, drainage and fuel-modification work near open space
  • Integration with patios, lighting and shade structures

What shapes the schedule

  • Design and plant selection
  • Planting season: fall through early spring, ahead of the dry summer
  • Oak permits and association review where they apply
  • Plant availability and ordering
  • Weather and the establishment period

Why entertainer's cabana was drawn together with the rest of the property

Decking, drainage, utilities, planting, shade and lighting all bear on where a feature goes and how it gets built. Settling them on one set of drawings is what keeps conduit out of the wrong trench and stops paving being cut to fit afterward.

  • Pool and spa A pool and raised spa set in a field of concrete pads with artificial turf joints.
  • Cabana and kitchen A gable-roofed timber cabana with a bar, and a full kitchen run along the dining terrace.
  • Planting A slat wall planted with herbs and trailing greenery, and white roses and climbing vines along the side-yard wall.
  • Paving and joints Turf joints between the concrete pads soften the deck and break up a hot, hard surface.
  • Lighting A lighting legend on the same sheet, so circuits went in with the rest of the work.

Frequently asked questions

What grows well in the Conejo Valley?

California natives and Mediterranean plants do the heavy lifting: toyon, coffeeberry, manzanita, ceanothus, sages, buckwheats and deer grass are natural companions to the oaks, and olive, rosemary and lavender suit the Mediterranean homes. The key is matching each bed to its exposure, since a south-facing slope and a shaded courtyard on the same lot need different plants.

Can we plant under our oak?

Carefully. An oak does best with a dry trunk in summer and undisturbed soil under its canopy, so we avoid lawn and regular irrigation beneath it, keep grade changes and trenching outside the root zone, and use mulch and a sparse, drought-tolerant understory instead of a thirsty bed.

Do I need a permit to landscape near an oak in Thousand Oaks?

Often, yes. The city's oak ordinance covers more than removal: grading, trenching, paving and pruning inside a protected zone generally need a permit. We map the protected trees during the site analysis and design around them, which keeps the application routine.

How does fire risk change what we can plant?

Mostly the planting closest to the house. The first several feet stay free of combustible material, the near zone is planted low and irrigated with lower-resin species, and hardscape and spacing break up continuous fuel. Further out, past the clearance zones, the garden can be much richer. We confirm your parcel's zone and any fuel-modification requirements during the site analysis.

Will you prepare our HOA landscape submittal?

Yes. Planting plans, specified materials and color selections drawn to the standard your association uses, with review comments worked through alongside the design. Rules differ between North Ranch, Lang Ranch, Dos Vientos, the lake community and Lake Sherwood, so we ask for your governing documents early.

When is the best time to plant in the Conejo Valley?

Fall through early spring. New planting roots in over the cooler, wetter months and goes into its first dry summer established. Fall planting coincides with the Santa Ana season, so new trees are staked and watered with that in mind.

Our property is on septic. Does that change the landscape?

It can. Many Lake Sherwood properties rely on septic systems, so we locate the septic field early and keep trees, irrigation and hardscape placed with it in mind rather than over it.

What does landscape design cost in the Conejo Valley?

It depends on the size of the planting area, the plant sizes specified, how much grading, drainage or fuel-modification work the lot needs and how much of the yard is included. Your designer sets the design fee at the first meeting, once the site analysis has measured the property.

Do you serve my part of the Conejo Valley?

Very likely. We design and build landscapes in Thousand Oaks, Westlake Village, Agoura Hills, Lake Sherwood and Simi Valley, and on the Las Virgenes side at Calabasas and Hidden Hills. Each community has its own page with an address checker.
