Design decision
Why this idea works
Wrapping the steps around a landing in an L lets the approach turn a corner gracefully and fits a raised entry into a tighter footprint. The full landing gives a safe place to stand and open the door, and the geometry reads as considered.
- The tradeoff
- The layout sets a clear direction, but it also commits the project to fixed relationships. Keep steps uniform around the turn and give the landing full depth before finishing.
- How to measure it
- Conceptual range: the L-shaped stepped element plus the wrapped landing figured as one platform.
On your property
Plan it for your site
Broom-finish the treads and landing for traction and round the nosings, and keep every riser and tread uniform around the turn. Give the landing real depth, keep the geometry clean at the corner, and pitch surfaces to drain away from the door.
- Keep every riser and tread uniform around the L so the turn stays safe.
- Give the landing at least 36 inches of depth to stand and open the door.
- Set footings below frost and pitch surfaces to drain away from the door.
Before forms are set
Build implications
- Confirm before estimating Uniform steps around the turn within code limits.
- Confirm before estimating A landing at least 36 inches deep.
- Confirm before estimating Footings below frost and drainage away from the door.
- 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 L-shaped steps complicate the geometry?
They need careful layout so risers and treads stay uniform around the turn, but the finishing is the same as straight steps. The care is in setting out the corner.
Why wrap the steps around a landing?
It turns a corner gracefully and fits a raised entry into a tighter space while keeping a generous platform at the door. Lay it out so the steps stay uniform.
- Best when
- Landings & entries
- Reconsider when
- Reconsider the idea if finished elevations, consistent stair geometry, drainage, and safe support cannot be resolved on the property.
- Verify first
- Keep steps uniform around the turn and give the landing full depth before finishing.
- Professional input
- Qualified concrete contractor; engineer for suspended, cantilevered, or supported stairs
