Landscape Design + Build · Portland, Oregon

The yard you keep meaning to build.

We design and build outdoor space for Portland homes — terraces, stonework, plantings, and the grading nobody notices until it rains. One crew, start to finish, at a price we fix before we dig.

A finished Portland backyard: a lawn edged by a low basalt wall and layered fern plantings, with a green craftsman house and Douglas firs behind, in soft overcast morning light.

Before / after

Drag the handle. It’s the same yard.

Every one of these started as a photo the homeowner was a little embarrassed to send us.

The same backyard finished: a level bluestone terrace with a fire bowl and teak chairs, a low basalt retaining wall and layered fern plantings.

A slope nobody could stand on

Two feet of fall across thirty feet of yard, so every barbecue happened in the driveway. We cut the grade into one level terrace, held it with a dry-stacked basalt wall, and planted the shade side with things that like a wet February.

A back door that led nowhere

The house had a beautiful back door and absolutely no reason to open it. We built the room that was missing — covered, warm, and usable in the eight months a year Portland is damp.

The same side yard finished: a crushed basalt path with bluestone stepping pads running between dense fern, hosta and hellebore plantings.

The side yard that flooded every winter

Roof water was landing four feet from the foundation and staying there until April. The pretty part took a week. The part that keeps the crawlspace dry took the other three.

What we do

Four things, done by the same crew.

We don't sub out the parts that matter. If it's on this list, the people who designed it are the people who build it.

  • Detail of a dry-stacked basalt retaining wall meeting the edge of a bluestone patio, moss in the joints.

    Terraces & stonework

    Bluestone, basalt, dry-stack walls, and steps that meet code and still look hand-set. If it holds soil back or holds a chair up, we build it ourselves — no subcontracted masonry.

  • A layered planting bed of sword ferns, hellebores and japanese forest grass against a weathered cedar fence.

    Planting design

    Plans drawn for the Willamette Valley specifically — natives, shade tolerance, and the short list of things that survive a wet February and then a dry August without a sprinkler on a timer.

  • A cedar pergola over a bluestone patio with a built-in bench, cream cushions and potted ferns.

    Outdoor living

    Pergolas, fireplaces, built-in seating, and low-voltage lighting. These are the parts that decide whether you use the yard in October or just look at it through the window.

  • An open drainage trench with a compacted gravel base, a coil of perforated drain pipe and a wheelbarrow, mid-installation in a residential backyard.

    Grading & drainage

    The unglamorous half, and the reason we get called after somebody else's patio. Water goes where we send it, or it goes into your basement. We solve that first, then build on top of it.

How it goes

Four steps, and you know the price before we dig.

The estimate is free and the number is real. Most of what goes wrong in this trade goes wrong because somebody skipped step one.

  1. We walk the yard

    About ninety minutes on site. We measure, dig a test hole to see what your soil and drainage are actually doing, and talk budget out loud. No charge and no pitch — you get our read either way.

  2. Design and a fixed price

    Plan drawings, a full plant list, and one number. That number doesn't move unless you change your mind, and change orders get priced before anyone picks up a shovel.

  3. We build it

    One crew from demo to final sweep — the same faces every morning. Dumpster and portable toilet are on us, and you get photos at the end of each week if you're at work.

  4. Hand-off, then a year of check-ins

    You get a watering schedule and a labelled plant map. We come back at six and twelve months to check establishment and replace anything that didn't take.

Project in depth · Council Crest

Three terraces on a twenty-two degree slope

The lot dropped nearly nine feet from the back door to the fence line, and the previous owners had answered it with a railroad-tie wall that was giving up. We took the hill in three moves instead of one: a seat-height basalt wall at the top for the dining terrace, a planted middle step to break the fall, and a wide bluestone stair down to a level lawn the kids could actually use.

What clients say

Three reviews, none of them about the patio.

  • They found the drainage problem two other bids missed. The terrace is beautiful, but the thing I tell people about is that my crawlspace is finally dry.
    Marisol ReyesBeaumont-Wilshire
  • Fixed price meant fixed price. I have remodeled a kitchen before, so I came in braced for the phone call. It never came.
    Dev BhattacharyaSellwood
  • Three winters in and everything they planted is still alive and roughly twice the size. That is the entire review.
