At a glance
Centre Spine staircases suit many homes because they keep the stair open at the sides and still provide a strong main support line.
The best result comes from early planning of layout, balustrades, tread finish and site access.
You do not need a full brief before you contact us, though photos and rough sizes help.
Building rules may apply. Check with Building Control for your project.

What makes a Centre Spine staircase different
A Centre Spine staircase uses one main support line under the treads. This gives an open look at the sides.
Where it works well
This style works well in open-plan homes, extensions and full refurbishments.
When another style may suit better
If the brief needs a wall-led floating look, a floating stair may suit better.
Checklist
- Gather room photos and a simple plan if you have one
- Note rough floor-to-floor height if known
- List who is on the project team
- Save examples you like from the gallery

Layouts and how they affect the room
Start with the way the stair needs to work in the room. Look at straight runs, quarter-turn layouts and landing space.
Open-plan rooms
In open-plan rooms, a Centre Spine stair can divide areas without blocking light.
Refurbishment openings
In a refurbishment, the existing opening and support points can shape the layout choice.

Ask about Centre Spine stairs
Structure basics in plain English
The spine carries the main load from the treads. The building still needs suitable support where the stair starts and lands.
Tread options, balustrades and lighting
Timber treads are common. Glass balustrades keep the look light.
Install constraints and lead time stages
Most projects move through a simple sequence: first brief, measured information or survey, drawings, sign-off, manufacture, then install. Site access and timing with other trades matter.
For homeowners
Think about daily use as well as the look. Tell us who uses the stair and what you want to improve in the room.
For builders and architects
Send plans, site photos, levels and any structure notes early. Mark access limits and the project stage.
Common mistakes
- Choosing the look before checking layout and access
- Leaving balustrade decisions until late
- Planning lighting after drawings are nearly done
- Ignoring install access until the last minute
