A staircase is far more than a functional connection between floors — it is a design statement that can define the character of a home. Whether you are replacing a tired, outdated staircase, designing one for a new-build, or converting a loft, the right staircase company can create a feature that transforms your hallway from a simple passageway into the most impressive space in the house.
Staircase design encompasses a wide range of styles and materials. Traditional timber staircases with turned spindles remain popular, while contemporary designs featuring glass balustrades, open treads, steel stringers, and floating cantilever steps are increasingly in demand. Spiral staircases solve space constraints in tight floor plans, and helical (curved) staircases make the ultimate architectural statement.
The UK staircase industry combines traditional joinery skills with modern manufacturing technology. Many companies now use CNC machining and 3D design software alongside hand-finished craftsmanship, delivering precision-engineered components with artisan quality. A professional staircase company manages the entire process: site survey, design and 3D visualisation, Building Regulations compliance, manufacture, delivery, and installation.
Building Regulations (Approved Document K) govern staircase dimensions and safety requirements: minimum width, maximum rise and going, headroom clearance, balustrade height, and spindle spacing. These are not optional and must be met for any new or replacement staircase. A reputable staircase company will design to these standards as a matter of course.

What to Look For When Choosing a Staircase Company
- Design capability — Look for companies offering 3D visualisation so you can see the staircase in your space before committing.
- Building Regulations knowledge — The company must design to Approved Document K standards as a minimum.
- Material range — Choose a company experienced with your preferred materials (timber, glass, steel, or a combination).
- Portfolio — Review completed projects similar to your vision in terms of style and scale.
- Site survey — A physical survey is essential to assess structural requirements, access, and existing floor-to-floor dimensions.
- Structural assessment — Some staircase designs (cantilever, helical) require structural engineering. Ask whether this is included or additional.
- Manufacturing process — Ask whether components are manufactured in-house or outsourced. In-house manufacturing offers better quality control.
- Installation team — Confirm that installation is carried out by the company's own team, not subcontracted.
- Lead times — Bespoke staircases typically take 6-12 weeks from design approval to installation.
- Reviews — Read reviews on HouseJester, focusing on design quality, installation neatness, and project management.
Frequently Asked Questions
How long does it take to replace a staircase?
The design and manufacturing phase takes 6-12 weeks for a bespoke staircase. Removal of the existing staircase and installation of the new one typically takes 3-5 days for a standard straight flight, 5-7 days for a half-turn or quarter-turn staircase, and 7-14 days for spiral, helical, or cantilever designs. During installation, access between floors is temporarily lost — your installer should discuss arrangements for temporary access or plan the work in phases. Add time for any structural work (new openings, steelwork) and finishing (plastering, painting, flooring).
Do I need Building Regulations approval for a new staircase?
Yes. All new and replacement staircases must comply with Building Regulations Approved Document K. Key requirements include: minimum clear width of 800mm (domestic), maximum rise of 220mm, minimum going of 220mm, minimum headroom of 2m, handrail height of 900mm (on the stair) and 1100mm (on a landing), and balustrade spindle spacing of no more than 99mm (to prevent a child's head passing through). A staircase company should design to these standards and, if necessary, arrange Building Control inspection and sign-off.
Can I replace my staircase without major structural work?
If you are replacing a straight flight with a similar design in the same position, structural work is usually minimal — the existing stairwell opening and support structure remain unchanged. Changing the staircase configuration (e.g. from straight to half-turn, or relocating the staircase) requires structural alterations including new openings, trimming joists, and possibly steel supports. This significantly increases cost and complexity. Glass and steel designs may require structural reinforcement at fixing points. Discuss structural implications at the design stage and budget accordingly.
What is a floating staircase?
A floating (cantilever) staircase has treads that appear to project from the wall with no visible support underneath. The structural support is hidden within the wall — a steel spine or individual steel brackets are fixed to the wall structure, and the treads are bolted onto these hidden supports. The effect is dramatic and sculptural. Floating staircases require a solid masonry or reinforced wall to carry the load — they cannot be fixed to standard stud walls without significant reinforcement. They typically cost £8,000-£30,000+ depending on materials and length, and require structural engineering calculations.
How do I choose between glass and timber balustrades?
Glass balustrades create an open, light-filled stairway — they are ideal for maximising natural light in hallways and making smaller spaces feel larger. Frameless glass (10-12mm toughened) offers the cleanest look. Timber balustrades are warmer, more traditional, and available in endless styles — from turned spindles for period homes to square contemporary balusters. Timber is generally cheaper and easier to repair if damaged. Glass requires regular cleaning to maintain its impact and can show fingerprints (especially at child height). For a contemporary home or a dark hallway, glass is transformative. For a period property or a family home with young children, timber is more practical.
