The Foundation of Every iGarden
The iFrame System
The iFrame is the precision-engineered steel structure that sits beneath every iGarden. Designed and developed in the UK, it provides a smarter alternative to traditional patios, decking, and hard landscaping methods.

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.
A Better Way
Traditional Groundworks vs iFrame
Concrete, Disruption & Delays
- Excavation and groundworks: weeks of disruption
- Concrete foundations that crack over time
- Expensive drainage systems required
- Restricted access sites can be impossible
- No access to services once laid
- Uneven results on sloped ground
Steel Precision, Zero Disruption
- Installs over any existing ground surface
- Galvanised steel that lasts decades
- Natural drainage: no additional systems
- No machinery required: ideal for restricted access
- Lift individual tiles to access services anytime
- Perfectly level finish on any gradient
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.
Visual Guide
The iFrame in Action
From challenging ground to flush thresholds: see how the iFrame system handles real-world situations.
Challenging Ground
Rubble, old concrete, uneven earth. The iFrame installs directly over existing surfaces without excavation. No skip. No disruption.
Follows Any Contour
Adjustable pedestals allow the iFrame to follow natural ground levels while creating a perfectly level surface above. Slopes and gradients become a feature, not a problem.
Precision Levelling
The iFrame is engineered to be perfectly level regardless of what lies beneath. Every leg is individually adjustable for millimetre-accurate results.
DPC Protection
The iFrame is completely independent of the building structure. It maintains the damp proof course integrity by sitting 150mm below DPC with full ventilation.
Flush Threshold Living
Create a seamless, step-free connection between your home and garden. Perfect for wheelchair users, mobility scooters, pushchairs, and future-proofing.
Elevated & Suspended
The iFrame can be installed at height for raised terraces, balconies, and roof gardens. Lightweight yet rated to 1000 kg/m².
Tree-Friendly Construction
Minimal ground disturbance makes the iFrame ideal for Tree Preservation Order (TPO) areas. Shallow pad stones protect root systems while the floating frame adapts to minor ground shifts.
Through-House Access
No side access? No problem. The modular iFrame components are lightweight enough to transport through the property. No cranes, no heavy machinery.
Every installation scenario is pre-mapped during our 3D laser survey. No surprises, no guesswork.

Material Advantage
Cold-Rolled Steel vs Aluminium Extrusion
Aluminium Extrusion
- Pre-cut lengths bolted together on-site
- Cut and trimmed to fit: waste on every job
- Adjustable feet assembled piece by piece
- Relies on installer skill for precision
- Higher energy cost to manufacture
- Made-up-as-you-go when hitting obstacles
Cold-Rolled Galvanised Steel
- 3D point-cloud scanned for millimetre accuracy
- CNC-cut to exact spec: zero on-site waste
- Arrives as a complete kit with assembly manual
- Precision-engineered regardless of installer
- More sustainable than aluminium production
- Every obstacle pre-mapped and accounted for
Built Responsibly
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.

What Our Clients Say
“I knew I wanted to have an igarden as soon as I saw the previous work portfolio and they didn't disappoint! We are really pleased. The best thing I've ever done for my garden.”
Paula Hawthorn
Porcelain Paving · Hampshire
“We moved house and the first thing we did was call iGarden Vision again. The iFrame system is genius: we couldn't imagine our new garden without it. That's two homes, two installs. Worth every penny.”
Matt McGregor
Second iFrame Install · Surrey
“If I had my traditional patio, I'd be out here pulling weeds and brushing every weekend. Now I just jet wash it back to brand new. There's no maintenance at all. It's transformed how I use my garden.”
