Architectural Landscaping Steelwork — Mansfield
Retaining walls, raised planters, edging, railings and structural garden features — fabricated to the same standard as your build, not as an afterthought.
Alchemist Fabrications design and manufacture bespoke landscaping steelwork for homeowners, landscapers and architects across Mansfield, Nottingham and the East Midlands. All steelwork is galvanised and powder coated to your specification — supplied only or fully installed.
What We Do
Landscaping steelwork is often the detail that separates a good garden from a great one. The retaining wall that holds a split-level terrace. The raised planter that anchors a planting scheme. The edging that keeps a resin path looking sharp five years after install.
We work directly with landscapers, architects and homeowners to fabricate structural and decorative steelwork that integrates cleanly with the wider build — coordinating on dimensions, finishes and installation sequence so nothing is retrofitted or compromised.
All steelwork is galvanised and/or powder coated for long-term outdoor performance. We supply only, or supply and fit.
We coordinate on dimensions, install sequence and fixings — so your steelwork arrives ready to drop into the build, not adjusted on site.
Ground-contact and below-grade steelwork is hot-dip galvanised before powder coating. No rusting out in five years.
If you have a landscape architect drawing, we'll work directly from it. If not, we'll take site dimensions and produce our own.
Powder coated in-house to your specification. Anthracite, black, sage, or matched to your existing palette.
What We Build
Statement steel structures that define a space rather than simply fill it. Arched pergola frames, fountain surrounds, curved overhead structures, decorative screen walls — designed to a brief and fabricated with the same precision as our structural work.
These commissions tend to be one-of-a-kind. If you have a design or a sketch, we'll work from it. If you have an idea but nothing on paper, we'll help you develop it into something buildable.
Steel edging keeps hard landscaping looking sharp for years — no rot, no movement, no creeping. Raised planters and retaining edges give structure to planting schemes and level changes. Privacy screens and trellis panels define zones without blocking light. All fabricated to your exact dimensions.
We supply individual elements or work alongside landscapers and builders to deliver coordinated steel packages across a full project.
External railings and balustrades for terraces, steps, raised decking and changes in level. Fabricated to building regulation requirements where applicable, or to a bespoke design spec where aesthetics lead.
We produce clean, minimal railing systems — vertical bar, horizontal cable, or solid panel infill — that look architectural rather than utilitarian. Welded handrails and post bases designed for the specific substrate.
Fire pit surrounds, outdoor stairways, water feature frames, privacy screens, overhead beam structures — if it's steel, outdoor and structural, we fabricate it. These are often the commissions that come without a precedent: a specific brief for a specific space, with no off-the-shelf solution.
We'll work from your brief or your architect's drawing, and advise on material and finish choices that will perform in the conditions.

Scope varies enormously — from a run of edging to a full retaining structure. Here's what shapes the number.
Landscaping steelwork typically ranges from £500 to £15,000+ depending on scope, material and complexity.
What affects the price?
Linear metres is the biggest driver for edging and retaining walls — more material, more fabrication time. Structural complexity matters for retaining walls: load requirements, ground conditions, and fixing method all affect how the steel needs to be specified. Finish choice (powder coat vs Corten vs galvanised) and whether we're supply-only or installing will also move the figure.
We quote per project — fully itemised, with nothing hidden. If you're working with a landscaper or architect, we're happy to quote directly to them.
