What surfaces can iFrame be installed over?

Virtually anything: existing concrete, old pavers, natural ground, soil, or even sloped and uneven terrain. The frame adjusts to accommodate the existing surface and produces a perfectly level finish regardless of what’s underneath.

How long does iFrame installation take?

The steel frame itself typically goes down in 1–2 days for a standard residential project. Total project time (including surface) is usually 3–5 days. We’ll confirm a timeline specific to your project at the quoting stage.

Can iFrame accommodate slopes and gradients?

Yes, that’s one of its primary advantages. The adjustable support components level out any gradient, so you get a flat, stable surface even on significantly sloped ground: without any earthmoving or retaining walls.

What happens if I need to access services under the frame?

Individual porcelain tiles or decking sections can be lifted to access anything underneath: drainage, cables, irrigation, or pipes. This is a huge advantage over traditional paving where you’d need to break up concrete to access below.

How does drainage work with iFrame?

The elevated frame design naturally promotes drainage. Water passes through the gaps between surface elements and drains away underneath the frame, just as it would on natural ground. No additional drainage systems are usually needed.

Does iFrame require machinery to install?

No. The lightweight steel components are assembled by hand on site. This makes iFrame ideal for gardens with restricted access: rear gardens, narrow side passages, and roof terraces where machinery can’t reach.

Is the steel frame visible when the surface is installed?

No. Once porcelain tiles or composite decking are fitted, the steel frame is completely hidden. All you see is a beautiful, level surface with clean edges and flush thresholds.

The Technology

What Lies Beneath

Traditional gardens are built on concrete: excavation, wet trades, weeks of curing. The iFrame eliminates all of it.

Cold-rolled galvanised steel. Precision-engineered. A floating floor system that installs directly over any existing ground: concrete, pavers, natural earth, even slopes. No digging. No concrete. No waiting. Then your chosen finish connects directly to the frame.

The Process

From Survey to Stunning in Days

Survey & Design

We measure your garden, assess the ground conditions, gradients, and access. Every frame is designed bespoke to your space: no guesswork, no waste.

Frame Assembly

Lightweight galvanised steel beams and pads are hand-assembled on site. No machinery, no concrete, no disruption to your garden. The interlocking system goes down in hours.

Levelling & Surface

The frame is precision-levelled to produce a perfectly flat platform, then your chosen porcelain or composite surface is fitted directly onto it. Every tile or board locks in with clean, flush edges.

Finished Space

A beautifully level outdoor area with flush thresholds, clean edges, and full access to services underneath: installed in days, not weeks.

Why Choose iFrame

The Invisible Foundation That Makes Everything Possible

The iFrame is a galvanised steel substructure that sits above your existing ground level, eliminating the need for traditional groundworks entirely. No digging, no concrete, no disruption. The lightweight interlocking system is assembled on-site to accommodate any slope, gradient, or ground condition: from old concrete to uneven soil. Once the frame is level, your chosen surface (porcelain or composite) fits directly onto it. The result is a perfectly flat, structurally sound outdoor space that can be installed in days, not weeks. And because everything sits above ground, you retain full access to drainage, cables, and services underneath.

8 Reasons to Build on iFrame

Efficient Installation

The interlocking system is installed on site without the need of labour intensive groundworks.

Seamless Integration

Choose your preferred surface options and enjoy flush to threshold internal and external levels.

Low Maintenance

The lightweight steel frame won't rot, creep or decay reducing the need for remedial work.

Function and Form

Each frame is configured to accommodate bespoke heights and design requirements.

Structural Satisfaction

The system installs over any ground surface or gradient to produce a stable and level finish.

Contemporary & Uncluttered

Conceal services for modular elements beneath the surface for a clean and minimalist finish.

Effective Drainage

The iFrame promotes quick and natural drainage without the need of additional systems.

Minimal Access Restrictions

The interlocking system doesn't require machinery and is a solution for most difficult to reach sites.

Sustainability by Design

100% Recyclable Steel

Cold-rolled galvanised steel is fully recyclable at end of life. Unlike composite decking or concrete, nothing goes to landfill.

No Concrete, No Wet Trades

Zero excavation, zero concrete, zero curing chemicals. The iFrame system dramatically reduces the carbon footprint of every garden project.

Zero On-Site Waste

Every beam is CNC-cut from 3D laser survey data. Nothing is trimmed on-site. No off-cuts, no waste materials, no skip hire.

Decades of Maintenance-Free Life

No annual treatments, no replacement cycles, no chemical cleaners. A jet wash once a year is all it takes.

For Professionals

Architects & Specifiers

The iFrame system is designed to meet the demands of professional specification. Cold-rolled galvanised steel, 3D point-cloud surveyed, CNC-manufactured to tolerances that eliminate on-site adjustment.

Whether you are specifying for a residential garden, a multi-unit development, or a commercial outdoor space, the iFrame provides a consistent, reliable foundation that can be surfaced in porcelain, composite, or natural stone.
