Design decision
Why this idea works
A long hillside climb is far more comfortable split into flights with a mid-landing terrace, which gives a rest point and a moment to enjoy the garden. The planted retaining edges hold the grade so each flight sits level and the climb feels manageable.
- The tradeoff
- The layout sets a clear direction, but it also commits the project to fixed relationships. Build the retaining and drainage, and keep flights uniform, before finishing.
- How to measure it
- Conceptual range: the stepped flights plus the mid-landing terrace and retaining edges figured separately.
On your property
Plan it for your site
Broom-finish the treads and terrace for traction and round the nosings, and keep every riser and tread uniform across the flights. Build the retaining edges with drainage, give the mid-landing real depth, and manage runoff down the slope.
- Keep every riser and tread uniform across the flights so the long climb is predictable.
- Give the mid-landing terrace real depth as a rest point and viewpoint.
- Build the retaining edges with drainage and manage runoff down the slope.
Before forms are set
Build implications
- Confirm before estimating Uniform steps across the flights within code limits.
- Confirm before estimating A mid-landing terrace at least 36 inches deep.
- Confirm before estimating Retaining edges with drainage and managed runoff.
- 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
- Fixing risers before final elevationsFinish layers at the landing or threshold can change the first or last riser and create an uncomfortable or unsafe flight.
- Allowing one irregular stepUsers expect a repeated rhythm; a single different riser height or tread depth is a common trip hazard.
- Treating open-looking stairs as ordinary flatworkCantilevered, folded, open, or suspended concrete stairs require engineered support, reinforcement, connections, and guard details.

Estimate similar stepsQuestions this idea raises
Do the retaining edges need engineering?
Low edges on stable ground may be within a competent installer, but taller retaining on a hillside becomes structural. Confirm the height threshold, drainage, and any professional design.
Why add a mid-landing on a hillside?
A landing breaks a long climb into comfortable flights, gives a rest point, and is often required by code beyond a certain rise. Give it real depth and a reason to pause.
- Best when
- Hillside steps
- Reconsider when
- Reconsider the idea if finished elevations, consistent stair geometry, drainage, and safe support cannot be resolved on the property.
- Verify first
- Build the retaining and drainage, and keep flights uniform, before finishing.
- Professional input
- Qualified concrete contractor; engineer for suspended, cantilevered, or supported stairs
