Design decision
Why this idea works
Splitting a sloped courtyard into two levels with broad low steps turns a grade problem into two usable terraces and a sense of layered space. The steps and planted edges hold the grade, so their uniformity and drainage lead the design.
- The tradeoff
- The layout sets a clear direction, but it also commits the project to fixed relationships. Keep the steps uniform and build the retaining edges with drainage before finishing.
- How to measure it
- Conceptual range: two terrace levels plus the broad steps and planted retaining edges figured separately.
On your property
Plan it for your site
Keep the concrete field calm so the levels and planting read cleanly, and slope both terraces to drain. Keep the broad low steps uniform and drained, build the planted edges with drainage as low retaining, and size each level for comfortable lounging.
- Keep the broad low steps uniform and drained between the levels.
- Build the planted edges with drainage as real low retaining.
- Size each level for comfortable lounging and slope both to drain.
Before forms are set
Build implications
- Confirm before estimating Uniform, drained broad steps between levels.
- Confirm before estimating Planted retaining edges with drainage.
- Confirm before estimating Each level sized for lounging and drainage.
- 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
- Starting with furniture instead of movementDining, cooking, and lounge zones need working clearances and a direct route to the house before the slab outline is fixed.
- Adding services after the pourGas, electric, water, drainage, lighting, and future conduit are easier to coordinate before concrete placement.
- Assuming the slab supports every featureRoofs, pergolas, kitchens, fireplaces, and seat walls often need separate footings or structural details.

Estimate a similar concrete areaQuestions this idea raises
Do the broad steps follow stair rules?
Yes, even broad low steps should be uniform and drained, since uneven steps trip people. Keep them consistent and confirm local rules.
Do the planted edges need engineering?
Low edges on stable ground may be within a competent installer, but taller retaining becomes structural. Confirm the height threshold and drainage.
- Best when
- Lounge courtyards
- Reconsider when
- Reconsider the idea if circulation, utility coordination, clearances, and independent support for built features cannot be resolved on the property.
- Verify first
- Keep the steps uniform and build the retaining edges with drainage before finishing.
- Professional input
- Coordinate the concrete contractor with utility and feature installers before the pour
