What StairBox does

StairBox, trading as AVC (Stairbox) Limited, is a UK-based manufacturer and direct-to-customer supplier of bespoke timber staircases and stair parts, operating from a single factory and head office in Stoke-on-Trent. The company combines CNC staircase manufacturing technology with hand-finishing, supported by over 100 years of claimed combined woodworking expertise, to produce made-to-order staircases in configurations including straight, winder, T-shape, open plan, oak, softwood, and contemporary metal-timber hybrids, with an average lead time of 7-10 working days. Its commercial model is anchored by a suite of proprietary online configurators — most notably the trademarked StairBuilder® tool, alongside GlassBuilder, Loft Stairs Designer, and Door Lining Designer — that allow customers to self-design, receive instant quotes, and order online without sales-intermediary involvement, with technical advisors available for guided support and own-fleet nationwide UK delivery.

Revenue is generated entirely through one-time unit sales across four streams: bespoke staircase orders, individual stair parts and accessories (spindles, newel posts, handrails, baserails, balustrades, finishes, fixings), glass balustrade systems, and staircase renovation/cladding products. Customers are split between two primary segments — homeowners and self-build/renovation consumers buying directly, and tradespeople (joiners, builders, carpenters) sourcing for client projects — with full payment required at point of order and quotes valid for 3 months. Distribution is direct via the stairbox.com e-commerce storefront, phone/email inside sales, a factory showroom, and trade show presence (Homebuilding & Renovating Show). StairBox is a wholly-owned subsidiary of Grafton Group plc, the London-listed diversified building materials group, and uses earned media exposure on BBC's DIY SOS and Channel 4's George Clarke's Remarkable Renovations as a brand-awareness channel.

StairBox designs, manufactures, and supplies bespoke timber staircases and complementary stair parts from its Midlands-based factory in Stoke-on-Trent. Customers configure orders online via the proprietary StairBuilder® tool or with support from technical advisors, and finished staircases are hand-finished and delivered nationwide across mainland UK via the company's own fleet of vehicles with a typical 7–10 working day lead time.

Product overview

StairBox is a UK-based manufacturer and supplier of bespoke timber staircases and stair parts.

Broad incumbents

• Wickes: Wickes is a UK home improvement retailer offering kitchens, bathrooms, timber, and building supplies, including basic staircase and stair-part ranges. A broad incumbent whose DIY-oriented stair-part catalogue competes with StairBox at the entry-level price point, but Wickes does not offer bespoke staircase manufacturing.
• JELD-WEN UK: JELD-WEN is a global manufacturer of doors, windows, and related interior building products with a significant UK operations footprint. While not staircase-specialist, JELD-WEN competes in adjacent millwork categories that overlap with StairBox's stair-parts and architectural woodwork range, and is significantly larger in scale.
• Travis Perkins: Travis Perkins is the UK's largest distributor of building materials and operates merchant and consumer brands including stair-parts ranges. Shares the Grafton-adjacent merchant landscape with StairBox but as a broad-line distributor rather than a specialist staircase manufacturer; relevant for trade-channel dynamics and raw-material sourcing.
• Howdens Joinery: Howdens is a UK trade-only kitchen and joinery supplier with an extensive depot network, primarily serving small builders. Comparable as a UK joinery/building-products trade channel operator but with a kitchen-centric product mix that only partially overlaps with StairBox's staircase focus.

Direct peers

• Neville Johnson: Neville Johnson is a UK-based bespoke staircase and home furniture manufacturer specialising in made-to-measure staircases, with online design tools and direct-to-consumer sales — a closely analogous business model to StairBox in the UK bespoke staircase market.
• Chase Joinery: Chase Joinery is a UK bespoke joinery manufacturer producing made-to-order timber staircases and architectural joinery for residential and commercial clients. Comparable to StairBox on bespoke timber staircase manufacturing capability, though smaller in scale and less e-commerce-led.
• Bisca: Bisca is a UK designer and maker of bespoke staircases, predominantly in glass, timber, and steel for high-end residential projects. Overlaps with StairBox on the bespoke staircase designer-fabricator proposition, though positioned at the premium end of the market.
• Richard Burbidge: Richard Burbidge is a leading UK manufacturer and distributor of stair parts, balustrades, and timber mouldings, supplying both trade and DIY channels. Directly comparable to StairBox's stair-parts and accessories business, with significant product catalogue overlap in spindles, newel posts, and handrails.
• Jackson Woodturners: Jackson Woodturners is a UK manufacturer of timber stair parts including turned and square spindles, newel posts, and handrails. Closely comparable to StairBox's stair-parts catalogue, primarily serving the trade and DIY renovation channel.

Emerging players

• StairFurb: StairFurb is an emerging UK direct-to-consumer staircase renovation brand offering oak staircase cladding kits and refurbishment products online. Overlaps with StairBox's renovation/cladding product line and competes for the same budget-renovation customer cohort with a digitally-led, narrower catalogue.
