DESIGN · PHILOSOPHY · BY JEFFERY RIDDLE
Design inside the place, not onto it.
Why design begins with the ground
Before I draw anything, I want to know what is already on the site. Not just what the survey shows — but what the soil does in July, which direction the cold air pools in February, which trees are performing and which ones the last owner planted against the grain of the place. That inventory is the first layer of the design. I am looking for the live oak that has outlived three homeowners and will outlive this one; the post oak hidden at the back of the lot whose root zone tells me exactly where I am not going to grade; the pattern of runoff after a heavy rain that has been writing itself into the clay for years. Those facts carry more weight on the drawing board than almost any aesthetic preference — because a garden that disagrees with them will argue back, quietly, every season, until it loses.
In this region the ground is not one thing. East of the Trinity River, the Blackland Prairie rolls over calcareous clay with a shrink-swell profile that cracks open in August and tightens shut in November; west, the Eastern Cross Timbers offers sandy loam over sandstone where a different palette wants to live. A planting plan that serves a Lakewood client will quietly fail a Prosper client, and the other way around. Reading that substrate correctly at the start — soil pH, drainage character, which native canopy species the block already supports — prevents the slow-motion failures that look like plant loss but are really design errors from the first day.
What place-narrative means as a design discipline
Place-narrative, the way I use the phrase, is not a sentimental idea. It is the discipline of treating what is already true about a site — its ecology, its hydrology, the architectural context of the house, the neighborhood the house was built to sit in — as a structural input to the design rather than a backdrop for it. A garden composed against that reading has to work harder every year to stay legible, because nothing in the site is reinforcing it. A garden composed with that reading reads as inevitable a decade in, and that is usually the register a client is trying to describe when they reach for the word “timeless.”
On a typical DFW residential project, that lens changes concrete decisions at every scale. Plant selection narrows to what the alkaline clay can actually support without amendment theater — Quercus fusiformis escarpment live oak on drier western sites, Q. virginiana southern live oak where the soil holds more moisture, Quercus stellata post oak where the Cross Timbers horizon allows it, Juniperus virginiana eastern red cedar as a reliable native evergreen structure plant, sideoats grama (Bouteloua curtipendula) where the sun carries it. Hardscape narrows to the stones this region was already making of itself — Lueders limestone quarried two hours west, Pennsylvania bluestone where the register calls for a cooler range, pea gravel, decomposed granite. Grading decisions get made around existing canopy drip lines rather than against them. Irrigation gets sized to the soils' actual absorption, not to a default schedule. The place stops being an obstacle; it becomes the design's best argument.

Design and build as one practice
There is a tradition in this industry of handing a drawing set from one firm to another — designer to contractor, one voice to another, with whatever gets lost in the translation becoming someone's problem later. We do not work that way. When I hand off to the build phase, I am handing off to myself or to Hayden or Tyler — the same Principal who read the ground with the client at the start. There is no translation loss because there is no translation. The person who drew the grading plan is the person standing on the site when the excavator arrives.
That changes what the drawings have to contain. A traditional designer-to-contractor handoff tends to protect the design by over-specifying every detail, because the drawing set is the only thing bridging the two firms. Our drawing sets can do different work: they name the species and the dimensions, but they also carry irrigation rough-in notes, mortar chemistry callouts, and sequencing detail because the person reading them will also be the one pouring the footings and setting the stone. The set reads less like a spec book handed off to a stranger and more like a field notebook a craftsman will return to week after week. That is an operational difference, not a marketing one.

What changed after February 2021
In February 2021, Winter Storm Uri held DFW under freezing air for five consecutive days and drove soil temperatures lower than any event in the region's recorded horticultural memory. That week killed plants we had been specifying for twenty years. It split irrigation manifolds that had passed every prior winter. It cracked mortar joints in terraces that had never flinched before. The industry's first response was to write the event off as a generational anomaly. Ours was to treat it as a data point that should change the work.
The planting list contracted. Species that failed the five-day freeze — queen palms, the tender pittosporums that had been routine, certain Podocarpus cultivars — came off our working lists. The palette we use now is the one with a documented record on the other side of the event: the native oaks above, Juniperus virginiana eastern red cedar as reliable evergreen structure, native grasses and forbs that went dormant and returned. We also took a harder look at which specimens were being sold as zone 8 but were really borderline 9a imports — a distinction that matters again, and will matter again the next time the polar vortex slips south.
The drawings changed too. Irrigation manifold placement is a design decision now, not a contractor's field call — we site manifolds in sheltered microclimates, call out insulation specs to match exposure, and document the drain-and-restart protocol for the homeowner in the handoff packet. Mortar chemistry notes sit alongside stone specs on terrace details. Resilience is a design decision now, built into the drawing set. It was not before Uri. What we learn at the one-year and three-year plant-performance reviews on each project flows back into the next project's Site & Story phase, which is how the discipline stays honest across a twenty-year practice.
What I look for when a project starts
A first conversation is usually a walk. I am listening for the shape of what the client is actually trying to make, which is almost never the shape they came in with. “We want a pool” often turns out to mean “we want the backyard to work for dinner with friends three nights a week between April and November.” “We want it to feel private” often turns out to be a canopy question before it is a fence question. The first visit is where I try to separate the feature list from the life underneath it, and where I start to sort what the site will support from what it will quietly refuse.
On the Site & Story walkthrough, I look at canopy before anything else — mature trees, their root zones, what is thriving and what is struggling. I read the soil with a probe, trace the drainage lines, note where water pools after a heavy rain, mark where the late-afternoon summer sun hits hardest. A photo survey shows the yard at one moment; a walkthrough shows the yard across the calendar year, which is what the design actually has to answer to.
“[OPERATOR: Jeffery quote, preserved: “The garden is a contract with the ground — a written agreement about what will be true on this site in ten years.”]”
How the practice stays honest
Every Alterra project closes with a written warranty and a documented one-year and three-year plant-performance review. That is not a customer-service flourish; it is the discipline's feedback loop. At one year, we walk the site and record what thrived, what limped, and what failed outright. At three years, we do it again. Those notes sit in a reviewable archive, and they flow back into the Site & Story phase of the next project — especially projects on comparable soils, microclimates, or post-Uri exposure profiles.
Honest reporting at those reviews is the quiet center of the practice. If a species we recommended underperformed, we want to know — because the next client on a similar site should not inherit the same bet. If a terrace detail is failing, we want to know — because the next terrace detail should not be the same drawing with the same assumption. A twenty-year practice in this region is only possible if we are willing to let what the ground tells us overrule what we thought we knew when we drew the plan.
An invitation
Most people who call are not sure yet what they want — they know the yard is not working, or they want to add something, or they've just moved in and want to understand what they have. That is the right time to call. We are not trying to close a sale in a first conversation; we are trying to figure out whether what you are setting out to make is work this practice can honestly do. Often it is. Sometimes it is not. The only way to know is to talk.
