A staircase is one of the most consequential commissions in a home. It is a route between floors, but it also occupies a prominent visual and structural position, often at the centre of an entrance hall or open-plan room. To commission a bespoke staircase successfully, you need more than a preferred timber or a saved image. You need a clear brief, an accurate survey, the right technical contributors and a maker whose design and installation process is suited to the building.

This guide is for homeowners, architects and interior designers planning a new stair, replacing an existing one or coordinating a staircase within a larger renovation. It explains what to prepare, who does what, why specifications matter and which decisions tend to affect the budget and programme most.

A good bespoke staircase maker UK clients can rely on will bring valuable practical knowledge. However, a staircase is not a purely decorative piece of joinery. Depending on the project, structural engineering, architectural coordination and building control input may all be required. CommissionIt can help you find and manage an appropriate specialist through its bespoke joinery, carpentry and furniture maker network, while the appointed professionals remain responsible for their own designs, advice and approvals.

Start with a staircase brief that can be built

The best brief gives a designer enough information to assess feasibility before committing to a particular look. A floating stair with glass, for example, may call for hidden support, carefully coordinated wall construction and early structural decisions. A traditional closed-string timber stair may be more straightforward, but still needs exact openings, finished floor levels and guarding details.

Begin by stating the problem to be solved. Is the existing stair too steep, noisy, dark, narrow or visually heavy? Are you creating a new opening as part of a loft conversion, rear extension or full refurbishment? The answer determines whether the maker is refining a known arrangement or helping to develop a custom staircase design from the ground up.

What information belongs in the brief?

• Property context: the address area, property type, period and whether the work is part of a wider build.
• Scope: a replacement stair, a new stair in an existing opening, or a completely new opening and stairwell.
• Drawings and photographs: architectural plans, sections, elevations, site photographs and any demolition or structural drawings already available.
• Levels and dimensions: floor-to-floor height, approximate opening size, room dimensions and headroom constraints, if known.
• Design direction: reference images, preferred character, desired degree of openness, and details you do and do not want.
• Materials: likely timber species, painted or natural finish, metalwork, glass, stone, carpet runner or other tread finish.
• Balustrade preferences: timber spindles, metal balusters, solid guarding, glass, handrail style and newel treatment.
• Practical needs: children, pets, reduced mobility, acoustic concerns, storage below the stair, lighting and daily traffic.
• Project programme: target installation period, other trades on site and any immovable completion date.
• Budget framework: a realistic comfort range or a clear request for options at different specification levels.

Include inspiration, but do not make it the only instruction. Images rarely reveal wall build-ups, concealed steelwork, floor finishes or the fixing strategy. Ask the maker to explain what would need to change for an inspirational image to work in your particular house.

How to commission a bespoke staircase: survey and feasibility

Do not order from approximate measurements. The staircase geometry depends on a set of linked dimensions, and small site errors can become serious fitting problems. The critical information includes the finished floor-to-floor height, the stairwell opening, floor construction, wall positions, ceiling line, headroom, landing dimensions and any obstructions such as doors, radiators, beams or services.

Who measures the site? Usually, the selected staircase designer or maker carries out a final detailed site survey before fabrication. This gives them control over the dimensions on which they will manufacture. In a complex build, the architect, main contractor and structural engineer may also issue coordinated drawings and setting-out information. Their information should not be treated as a substitute for the maker’s own pre-production check.

For a new opening, the survey should identify what is actually supporting the surrounding floor and walls. Existing buildings can hold surprises: uneven floors, out-of-plumb walls, altered joists and concealed services are common. A sensible process includes a feasibility discussion before the design is fixed, followed by a measured survey once opening sizes and finished floor build-ups are sufficiently certain.

It is useful to agree a dimensional responsibility schedule. This records who confirms the structural opening, who controls floor levels, when plaster and flooring are complete, and when the maker is permitted to manufacture. It reduces the risk of a beautifully made stair arriving before the site is ready to receive it.

Bring in the right professionals at the right stage

Which professionals are required? It depends on the scope. A like-for-like replacement in an established stairwell may principally involve a specialist maker, installer and the relevant approval route. A stair that changes an opening, bears on altered structure, has unusual support conditions or forms part of an extension will often require more coordination.

• Architect or architectural designer: develops layouts, coordinates the staircase with the plan and may prepare drawings for consent or construction.
• Structural engineer: advises on structural openings, trimmers, supports, connections and load paths where these are affected. The engineer should be appointed directly for structural advice where needed.
• Staircase designer and maker: resolves manufacture, visual detailing, tolerances, materials, fixings and installation methodology.
• Main contractor: prepares openings, sequencing, site access, protection and interfaces with plastering, flooring, electrics and decorating.
• Building control body or approved inspector, as applicable: considers compliance under the relevant process. They are not replaced by a maker, designer or commissioning platform.
• Interior designer: coordinates the stair with finishes, lighting, joinery, colour and the wider visual scheme.

In England and Wales, stair and guarding work may engage Building Regulations requirements, with the applicable route and requirements depending on the nature and location of the work. Scotland and Northern Ireland have their own systems. Ask the project lead and building control body what applies before construction begins. A maker can design to an agreed brief and technical information, but should not be assumed to provide structural engineering or statutory approval unless this is expressly included in their appointment.

Early coordination is especially important for cantilevered, folded-plate, helical or apparently floating designs. Their clean appearance often depends on structure and fixings being planned well before finishes conceal the relevant walls and floors.

Choose the form, materials and balustrade as one design

Staircases are systems, not collections of independent finishes. The structural arrangement, tread thickness, stringer type, balustrade and handrail all influence one another. Decide the overall character first, then test the details against the building and your day-to-day use.

Common design directions

• Closed-string timber stairs: adaptable and familiar, suitable for painted, traditional or contemporary schemes.
• Open-riser stairs: bring light through the stair, but require careful attention to guarding, sightlines and the intended users of the home.
• Central or side-stringer stairs: can give a lighter, more architectural profile, with steel or timber elements expressed or concealed.
• Feature timber stairs: suited to visible grain, carefully matched boards and refined hand-finished details.
• Steel and timber combinations: useful where a slim support line or industrial note is wanted, while retaining warmer treads.
• Curved or helical stairs: visually striking but demanding to measure, model, manufacture and install.

Timber is valued for warmth and repairability, but species, grade, grain direction and finish all alter the final effect. Oak can feel robust and traditional or very contemporary depending on the detailing. Ash often offers a pale, lively grain. Painted timber can integrate a stair into period architecture and make future touch-ups more straightforward. Metalwork may be powder coated, patinated or left with a specified finish, while glass requires a considered approach to edges, fixings, cleaning and reflections.

Balustrades deserve early attention because they are both a safety element and a dominant visual feature. Ask to see full-size samples or detailed drawings of handrail profiles, junctions, newels, metal finish, glass fixing points and how the balustrade meets the floor. A handrail that feels good in use and a guarding solution that works with the required geometry are more important than a fashionable detail copied without context.

Understand Building Regulations, drawings and sign-off

Building Regulations should inform the design rather than be checked only at the end. Stair pitch, rises, goings, headroom, landings, guarding and handrails are interrelated. A change to one can affect the others. Requirements can vary according to the building type, work type and jurisdiction, so obtain project-specific guidance from the appropriate building control route and qualified professionals.

Before fabrication, ask for drawings that make the proposal intelligible. They need not all be elaborate presentation drawings, but the package should clearly show the stair plan, elevations or sections, key dimensions, materials, tread and riser arrangement, strings, balustrade, handrails, newels, landing edges, fixing locations and interfaces with adjacent finishes.

It is also wise to record assumptions. Has the design allowed for the final thickness of engineered timber, stone, carpet, tile or underlay? Will the wall behind a handrail be sufficiently robust once plasterboard linings are installed? Who supplies and positions integrated lighting? Is the underside to be enclosed, plastered or left visible? These questions can prevent late compromises.

What affects bespoke staircase cost?

What affects cost? The principal cost drivers are complexity, materials, structural interfaces, access and the amount of design development required. It is not reliable to compare quotes solely by the number of steps or a photograph of the intended style.

• Geometry: straight flights are generally simpler than quarter-turn, winder, curved or helical forms.
• Structural demands: new openings, hidden supports, steelwork, altered floors and complex fixing details add coordination and work.
• Materials and finishing: selected timbers, bespoke metalwork, curved components, glass and specialist coatings affect both supply and labour.
• Balustrade complexity: repeated standard components are different from individually detailed metalwork or bespoke glass systems.
• Site conditions: restricted access, occupied homes, protection requirements, limited parking and awkward lifting routes can affect installation planning.
• Design and prototyping: detailed drawings, samples, templates and mock-ups are valuable where the stair is a major architectural feature.
• Scope boundaries: removal, making good, decorating, electrics, flooring, structural works and approvals may sit outside the maker’s quotation unless listed.

Request an itemised proposal that distinguishes design, survey, fabrication, delivery, installation and exclusions. Ask what happens if site dimensions change after sign-off, whether changes are priced before proceeding, and what level of finish is expected from adjacent trades. This makes quotations comparable and protects the relationship with the maker.

Plan the design, fabrication and installation programme

How long do design, fabrication and installation take? There is no universal answer because every staircase is linked to its site readiness and level of complexity. A straightforward commission can move more quickly than a highly detailed feature stair, but neither should be scheduled on the assumption that it is an off-the-shelf product.

Allow time for an initial conversation, information review, site survey, concept development, technical drawings, revisions, approvals, material procurement, workshop fabrication, finishing, delivery and installation. Curved work, specialist glass, bespoke metalwork and coordination with structural alterations can extend the programme. The maker’s workload, material availability and access constraints also matter.

The most reliable approach is to ask for a staged programme tied to clear decision points. Do not treat a provisional lead time as a guarantee before the design is signed off and the site is measured. Fabrication should begin only when the necessary dimensions, interfaces and finishes are sufficiently fixed.

Keep the installation day orderly

• Confirm safe access, parking, unloading and a clear route into the property.
• Ensure structural works and openings are complete and dry enough for the specified materials.
• Protect finished floors, walls and nearby joinery before delivery.
• Coordinate electricians if the stair incorporates lighting or concealed services.
• Agree who makes good around strings, landings, skirting and wall finishes after fitting.
• Arrange a final inspection of alignment, finish, handrails, guarding and any snagging before other trades obscure the work.

Questions to ask before appointing a maker

A strong portfolio is helpful, but the appointment should also test process. Ask whether the maker has delivered comparable work in buildings with similar constraints, how they survey, who produces the technical drawings, which elements are made in-house and how they manage site changes. Review samples in the intended light where possible, particularly for timber tones, paint sheen, glass and metal finishes.

Clarify the contract basis before paying a deposit: the agreed scope, drawing approval process, payment stages, design ownership and use, lead time assumptions, variation procedure, installation responsibility, warranties and aftercare. Keep all decisions in writing. Bespoke work benefits from decisive communication, but it should never rely on undocumented assumptions.

Frequently asked questions

Can I use images from another project as my brief?

Yes, as visual references. Use several images to communicate the qualities you like, then ask the maker how the idea can be adapted to your dimensions, structure, regulations and budget.

Should I appoint the staircase maker before the structural engineer?

For work involving a new opening or unusual support, it is often useful to involve both early. The maker can advise on the desired form and fixing needs, while a structural engineer addresses the affected structure. The project lead should coordinate the sequence.

When should final floor finishes be chosen?

Choose or specify them before final stair dimensions are released for manufacture. Finished floor build-ups influence the stair’s geometry, thresholds and landing details.

Can a bespoke staircase be installed in an occupied home?

Often, yes, but it needs careful planning. Discuss access, dust control, temporary safety, protection, working hours and whether the existing stair can remain in use during the works.

Take the next step with a well-managed commission

A bespoke staircase succeeds when the visual ambition, technical constraints and site programme are resolved together. Gather your drawings and references, identify the decisions that need structural or approval input, and seek a maker who is comfortable explaining the route from survey to installation.
