About Harrowfield
A valley crew that builds exactly what it draws.
25+Years in the valley
Harrowfield started in 2001 with one truck and an account at a basalt quarry twenty miles south. We still draw every garden ourselves, and we still build it ourselves — no brokered subcontractors, no crew you have never met turning up on day one.
Learn moreLandscape design
A measured survey, a drawn plan and a fixed written price before anyone lifts a shovel.
Garden construction
Basalt, bluestone, cedar, drainage and planting — built by the same people who drew it.
What we do
Stonework, planting
and drainage that
suits Oregon rain.
Everything below is done by our own crews on our own payroll, from the survey through to the last plant in the ground.

Selected work
Our work speaks through stone and water.
Project 01
Rear garden, Dunthorpe
A bluestone path, a level lawn and deep borders set under the existing firs. Built over one spring, with the drainage cut before a single stone went down.
Explore
Project 02
Hillside terraces, West Linn
Three levels of dry-laid basalt on a slope nobody could stand on. Planted in autumn so the roots had the wet months to take hold.
Explore
Project 03
Shade garden and rill, Sherwood
A basalt water channel running under Douglas fir, planted for wet ground and low light. Photographed in February, which is when it looks best.
Explore
Project 04
Garden lighting, Lake Oswego
Low warm path lights and tree uplighting, laid in at the same time as the terrace so nothing is surface-run and nothing is visible by day.
Explore
The same ground
The proof is the same patch of ground.
Every pair below is one camera position, one house, one season. Nothing has been swapped for a prettier garden somewhere else.
Sloping back lawn
Tualatin · 6 weeksA worn slope and a rotting sleeper wall, terraced in two courses of dry-laid basalt with a bluestone terrace at the house and a level lawn below it.
Cracked concrete patio
Oregon City · 4 weeksForty-year-old concrete lifted, the grade re-cut to drain away from the house, then sawn bluestone laid to a tight joint with a hydrangea border along the porch skirt.
Dead side yard
Milwaukie · 3 weeksMud and builder's gravel turned into a stepping-stone shade walk, with a slot drain along the wall and a planted strip of fern, hellebore and salal down the fence line.
Reviews
What the neighbours say.
They surveyed the slope, drew it, priced it, and then built exactly that. The basalt wall has not moved in four winters.
Marta Vance Lake Oswego · 5 out of 5
Our patio flooded every November. Harrowfield fixed the grade first and the terrace second. That order was the whole answer.
Doug & Priya Ellery West Linn · 5 out of 5
The same four people on site every day for five weeks, and they swept the drive before they left. Every time.

How it works
What actually happens after you call.
Three steps, and you will know the price before we break ground.
Book a site visit
The site visit
We walk the ground, take levels and talk about where the water goes before anything else. About an hour, and it costs nothing.
The drawing and the price
A measured plan and a fixed written price. Change it as many times as you like before you sign it — that part is free too.
The build
Our own crew, a start date in writing, and a named foreman whose number you have from the first day to the last.
Why Harrowfield
Four things that decide how a garden ages.
-
Drainage before decoration
Willamette clay moves. We cut the grades and set the drains before a single stone is laid, which is why our terraces are still flat ten years on.
-
Basalt from an hour away
Local quarried stone, so the wall matches the ground it stands in — and the haulage is not buried in your price.
-
Our own crews, on our own payroll
No brokered labour and no day rates. The people who drew your garden are the people who turn up to build it.
-
A five-year workmanship warranty
In writing, covering stonework and drainage, and it transfers to the next owner if you sell.
Where we work
The west side of the valley, and not much further.
We keep the radius tight on purpose. A crew that can be back on your drive the same afternoon is worth more to you than a bigger map is to us.

Questions
The six we get every week.
What does a garden like this cost?
Most full builds we take on land between $45,000 and $180,000, and small stone or drainage jobs start around $12,000. The site visit and the drawn plan are free, so you get a real number before you are committed to anything.
How long does a build take?
Three to eight weeks on site for a typical garden, plus two to three weeks for the drawing beforehand. We give you a start date and an end date in the contract, not a range.
Do you work through the winter?
Yes — stonework, drainage and cedar carry on all year here, and winter is the best time to plant bare-root. We only stop for hard frost, which in this valley is a handful of days.
Do you maintain the garden afterwards?
If you want us to. About half our clients take a seasonal visit — pruning, bed edges, irrigation start-up and shut-down. There is no obligation and it is not bundled into the build price.
Are you licensed and insured?
Registered with the Oregon Landscape Contractors Board, bonded, and carrying general liability and workers' compensation. We send the certificates with the quote without being asked.
Can you build from my architect's drawings?
Often, yes. We will usually want to re-survey the levels and price the drainage properly first, and we will tell you plainly if something on the drawing will not survive a Willamette winter.
