What we do and how we do it
What makes Open Riser Staircases work in the UK is usually invisible once it is finished. You are mostly dealing with a mix of period and modern stock around here, so openings vary more than people expect. the full range of UK exposure conditions is the local complication, and coating failure followed by rot at the joints is what it eventually causes. The detail we will not compromise on is open treads that still satisfy the 100mm sphere rule under Part K.
A surveyor visits first and records the real dimensions, at several points on each opening. Get in touch and we will be straight with you about cost and timescale.
One thing that catches people out here: specification should always be matched to local exposure.
Specification
- Engineered hardwood or slow-grown softwood, FSC certified
- Factory-applied microporous finish in any RAL or heritage colour
- Sealed units, slim-cavity units or single glazing with putty line
- Manufactured to survey dimensions, not to a stock size chart
- Delivered UK-wide with chain-of-custody paperwork
Rise, going and headroom
Three numbers decide whether a staircase is comfortable or awkward, and they are the first things we measure.
Rise
Maximum 220mm per step for a private stair under Part K. Consistent to within 5mm across the whole flight, because the foot notices what the eye does not.
Going
Minimum 220mm. Rise and going together must satisfy the pitch rule, which is why a flight cannot simply be shortened to fit a smaller opening.
Headroom
2m measured vertically from the pitch line. This is the constraint that most often forces a winder instead of a straight flight.
Set out from your rise
Every flight is calculated from the actual floor-to-floor height, measured on site.
Part K compliant
Rise, going, headroom and guarding checked against Building Regulations before manufacture.
Workshop made
Assembled and dry-fitted in the workshop before it ever comes to site.
Installed by our own fitters
The people who fit it work for us, so responsibility does not get passed around.
What clients tell us
Feedback collected directly from completed projects. Full written references are available on request before you commit.
“The headroom was tight and they redesigned the winder rather than telling us it could not be done.”
Verified client, UK-wide“Dry-assembled in the workshop first, so installation day was genuinely uneventful.”
Verified client, UK-wide“No squeaks at all a year on, which was the whole reason we replaced the old one.”
Verified client, UK-wideWhat happens next
Four steps from first call to installed joinery. No pressure at any stage.
Site survey
We measure the opening, the floor-to-floor and the headroom ourselves.
Design and setting out
You see the layout and tread arrangement before anything is cut.
Workshop manufacture
Made and dry-assembled in the workshop, then finished.
Installation
Fitted by our own team, with the balustrade set out on site.
Frequently asked questions
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
Can you work on a listed building?
Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
