Design decision
Why this idea works
A split-level courtyard embraces a grade change instead of fighting it, giving two distinct usable levels connected by steps and softened by layered planting. That approach turns a sloped, awkward space into a dynamic composition with room to gather on each level and a green transition between them.
- The tradeoff
- The layout sets a clear direction, but it also commits the project to fixed relationships. Resolve the two levels, their retaining, and the connecting steps first.
- How to measure it
- Conceptual range: two level courtyards plus connecting steps and retaining, measured separately.
On your property
Plan it for your site
Keep both levels calm and even, with the connecting steps broad and safe and the retaining detailed to hold and drain. Let the layered planting soften the level change so the two courtyards feel connected rather than divided.
- Keep both levels even and their connecting steps broad and safe.
- Size the retaining between levels and its drainage for the grade.
- Use layered planting to soften and connect the two levels.
Before forms are set
Build implications
- Confirm before estimating Two even levels with safe connecting steps.
- Confirm before estimating Retaining and drainage sized for the grade.
- Confirm before estimating Layered planting that ties the levels together.
- Measure the site and establish elevations Record boundaries, thresholds, grade changes, utilities, and the dimensions of vehicles, furniture, equipment, or structures that affect the layout.
- Test how the space will be used Check walking routes, turning paths, door swings, working clearances, maintenance access, and the route back to the house or street.
- Resolve drainage, services, and structural support Decide where water goes and coordinate drains, conduit, irrigation, fuel, electrical work, footings, and independent supports before forms are set.
- Define and estimate each concrete element Confirm the slab or footing section, base, joints, edges, and finish, then estimate simple measurable fields separately from steps, walls, drains, and supported features.
Prevent these problems
- Calling a retaining element decorativeA wall or planter that holds soil or water needs support, reinforcement, drainage, and often professional review.
- Hiding runoff with plantingA rain garden, swale, or planted edge must receive water intentionally and have a safe overflow route.
- Choosing the finish before defining the jobSeat walls, planters, edging, terraces, and retaining walls may look related but carry very different loads and details.

What is a split-level courtyard?
A courtyard resolved into two usable levels connected by steps, embracing a grade change rather than fighting it. It turns a slope into a dynamic, gathering-friendly space.
How are the two levels connected?
By broad, safe steps and softened with layered planting, over retaining sized for the grade. The steps and planting make the levels feel connected.
- Best when
- Terraces & grade transitions
- Reconsider when
- Reconsider the idea if retained soil or water, footing and reinforcement needs, drainage, and long-term access cannot be resolved on the property.
- Verify first
- Resolve the two levels, their retaining, and the connecting steps first.
- Professional input
- Landscape or concrete contractor; engineer for retaining or structurally loaded work
