When a standard set of external steps simply won’t fit, bespoke steel fabrication is the answer. At a residential property in Hampstead, North London, our team at Staired was brought in to solve a tricky external access challenge — a 660mm threshold rise within a narrow 1080mm side passage. This is exactly the kind of project where custom external metalwork makes the difference.

The Problem: A Tight-Space External Access Challenge

The property required safe step access to an elevated external door threshold, but the driveway clearance left almost no room for a permanent fixed structure. Off-the-shelf external door steps weren’t an option. The homeowner needed a solution that was sturdy enough for daily use, weather-resistant for a London climate, and compact enough not to block the passage permanently. The solution: a bespoke wall-mounted retractable steel step unit — designed, fabricated and installed entirely by Staired.

Bespoke Design: Getting It Right Before Fabrication

Every custom steel step project starts with a professional site survey. Our team visited the NW11 property to confirm wall substrates, measure the exact threshold rise, and assess clearance within the narrow driveway width. Accurate site data is what allows us to fabricate with confidence. From the survey, we produced full CAD drawings of the folding mechanism — a three-tread configuration at approximately 165mm riser heights, in line with UK building standards for external residential access steps. Every measurement was designed around the specific constraints of the site.

Custom Steel Fabrication: Built for the British Outdoors

The retractable step unit was custom-manufactured from high-grade mild steel, with:

• • Anti-slip steel grating treads for safe footing in wet conditions

• • An integrated hinge and locking mechanism for smooth retraction

• • A fold-flat wall-mounted design — fully extended for use, folded flush when not needed

• • Corrosion-resistant primer as a base coat

• • Weatherproof black powder coat finish for long-term outdoor performance

This is the kind of bespoke external metalwork that simply cannot be bought off a shelf. From the folding mechanism to the tread pattern, every element was fabricated for this specific property.

Installation: Fixed, Tested, Signed Off

Our installation team delivered and mechanically fixed the unit to the external facade using fixings matched to the confirmed wall substrate. Once installed, we carried out full testing of the retraction cycle and safety checks before handover. The result: a clean, reliable external access step that folds away when not in use and holds firm when it matters.

Why Bespoke External Steel Steps?

Off-the-shelf external steps are designed for standard situations. When you’re working with an elevated threshold, a narrow side return, or a listed property where aesthetics matter, bespoke fabrication is the only route to a solution that genuinely fits. At Staired, we design and fabricate custom external steel steps across London and the UK — from single retractable units like this to full external staircases and fire escapes. Every project is built to UKCA/EN 1090 standards, with materials and finishes selected for the British climate. Common applications for bespoke external steel steps include:

• • Elevated external door thresholds

• • Side return and narrow driveway access

• • Garden level changes and terrace access

• • Commercial and residential external access

• • Replacement for deteriorating concrete steps
