Build the bones of the yard.
Retaining walls, seat walls, raised planters, and architectural pony walls — the structural elements that turn a sloped lot into terraces, define an outdoor room, and add planting beds at the right height. Engineered, drained, and built to last.
For terraces, seat walls, planters & pony walls
Walls do real work.
A good wall isn't decoration — it's structure. It holds back soil, levels a yard, anchors a seating zone, or lifts a planting bed to a comfortable height. Done right, you don't notice the engineering; done wrong, it cracks, leans, or fails the first wet winter.
Every wall we build over 3 ft is engineered and permitted. We pour concrete footings, install drainage pipe behind the wall, and use stamped block, dry-stack stone, or stucco-veneered CMU depending on the look you want. Seat walls get a comfortable 18" cap height; planters get drainage and root barriers. The result holds shape, drains clean, and matches the rest of your landscape.
Wall & planter styles
Six wall systems.
From a low Belgard seat wall around a firepit to a 6-ft engineered retaining wall reclaiming a sloped backyard. We pick the system based on height, soil, and the look — modern smooth stucco, tumbled block, or full-stone veneer.

8ft
Max retaining height
Engineered & permitted retaining walls up to 8 ft. Multi-tier for taller grade changes.
18"

Perforated pipe + 12" of drain rock behind every retaining wall over 3 ft.
25+yr
Expected lifespan
Properly footed & drained walls easily last 25 years with no maintenance.
Where walls excel
One element, four jobs.
Walls do four very different things in a yard — and the right wall for each job is rarely the same wall. We design and engineer to the function first, then dress the wall to match the architecture of the home.
Retaining
Reclaim sloped lots.
Engineered retaining walls turn an unusable hillside into flat, terraced living space. Permitted, drained, and built to handle wet-season soil pressure.
Seating
Seat walls & firepit zones.
Low walls at 18" cap height define an outdoor room and double as bench seating. Pair with a firepit, BBQ island, or planter for a finished outdoor space.
Planters
Raised planter beds.
Lift the garden to a comfortable working height. Built with drainage and root barriers so plants thrive and walls stay clean.
Privacy
Pony walls & pool surrounds.
Architectural pony walls add privacy and visual weight without going full-fence. Common around pool decks, side yards, and street-facing patios.
Our installation process
From footing to final cap.
Walls fail at the footing or the drain — almost never at the face. That's why every wall over 3 ft gets an engineered footing, drainage rock, perforated pipe, and a permit before we lay the first block.
01
Site survey & engineering
We measure existing grade, soil conditions, and the space available behind the proposed wall. Anything over 3 ft gets stamped engineering and a city permit before construction begins.
02
Excavation & footings
A trench is dug to the engineered depth, rebar is tied per the drawings, and the concrete footing is poured. Footings cure for 5–7 days before we set the first course of block.
03
Block courses & rebar
Block is set in mortar with vertical rebar tied into the footing. Cells are grouted at engineered intervals — every 16" or 24" depending on the wall's height and load.
04
Drainage & backfill
Perforated drain pipe is laid behind the wall, surrounded by 12" of clean drain rock and wrapped in geotextile filter fabric. Backfill is compacted in lifts to prevent settlement.
05
Veneer or finish coat
Stone veneer is set in mortar, stucco is troweled in two coats, or block faces are sealed and painted — depending on the finish you've chosen. Caps are mortared on top.
06
Final inspection & cleanup
City inspector signs off on engineering, footings, and drainage where required. We power-wash the wall, seal joints, and clean the work area before final walkthrough.
