Why Every InFrame Garden Room Starts With Steel
As seen in:
Beautiful finishes are easy.
The structure hidden behind them is what determines how your garden room performs for the next 30 years.
The Structure That Sets InFrame Apart
Our build starts with a precision-engineered steel frame, ensuring durability and strength from the ground up.
Steel has a predictable structural strength. Unlike timber, it does not expand, contract or twist significantly as moisture levels change.
That means doors remain aligned, glazing performs correctly and internal finishes stay looking their best for years.
Unlike timber there is
No Rot
No Termites
No Movement
No Deterioration
Robust, reusable, recyclable and adaptable.

Steel Framed Garden Rooms
screw pile foundations
We build every InFrame garden room on precision-engineered ground screws, creating a strong, stable foundation without the mess, delays or environmental impact of traditional concrete bases. Faster to install and kinder to your garden, they provide the perfect foundation for our steel frame system.
- Minimal disruption – No extensive excavation or large concrete pours.
- Faster installation – Foundations are typically completed in a single day.
- Precision engineered – Accurately installed to create a perfectly level base.
- Environmentally friendly – Less concrete, less waste and a lower carbon footprint.
- Protects your garden – Preserves existing landscaping and reduces damage to surrounding areas.
- Built to last – A durable, stable foundation designed for decades of performance
Designed Without the Limits of Timber
Steel doesn’t just make a garden room stronger. It gives you far greater design freedom.
Unlike timber, steel can span longer distances while using slimmer structural sections, allowing us to create light-filled, contemporary spaces with fewer design compromises.
Wider Glazing
Create expansive windows and larger glazed elevations that maximise natural light.
Larger Bifold & Sliding Doors
Steel’s superior strength allows for wider door openings, creating seamless indoor-outdoor living.
Slimmer Sightlines
Thinner structural sections mean less frame and more glass, delivering a cleaner, more architectural appearance.
Open Plan Interiors
Longer spans reduce the need for bulky supports, giving you flexible, uninterrupted internal spaces.
Higher Ceilings
Achieve impressive ceiling heights that enhance the sense of space and create a truly luxurious feel.
Contemporary Architecture
From striking corner glazing to minimalist designs, steel enables the bold architectural features that define premium garden rooms.
Architects understand these benefits immediately because they know what steel makes possible. Homeowners simply experience a garden room that feels larger, brighter and more luxurious every day.

Year Round Use
Built Like a Modern Home. Not a Garden Shed.
Steel has become one of the most widely used structural materials in commercial buildings, apartment blocks and modern homes. At InFrame we believe your garden room deserves exactly the same level of engineering rather than being built like an oversized shed.
Strength You Never See. Performance You'll Notice Every Day.
Anyone can make a garden room look beautiful on completion day.
The real test is how it performs after ten winters, thousands of opening and closing cycles, changing seasons and everyday family life.
That’s why every InFrame garden room begins with steel.
Because true luxury starts with confidence in what’s beneath the surface.
Those aren’t discussed by competitors.

InFrame Garden Rooms are the only company offering high grade warm roof technology to every garden room.
A warm roof is a type of roof that is designed to conserve heat. This is done by placing the insulation on top of the roof instead of between the rafters.
Generally, warm roofs are more effective than cold roofs at keeping the building warmer in winter and cooler in summer.
A warm roof allows heat to be retained within the building. Warm roofs are simply insulated more efficiently than cold roofs because of the way they are formed.

Unmatched Strength of
Steel
Steel frames offer unmatched structural strength and resilience, ensuring your garden room withstands the trials of time, even in harsh weather conditions.
This durability guarantees your space remains secure and steadfast, shielding against strong winds, heavy snowfall, extreme temperatures, and other environmental challenges. Furthermore, steel frames resist pests like termites and other wood-boring insects, which can wreak havoc on timber structures. Opting for a steel frame means investing in a garden room that maintains its structural integrity and aesthetic appeal for years to come.
Steel is a modern construction material that results in a garden room that rivals any house extension. Traditional timber frames provide cost effective methods of creating a garden room. On the downside, they require extensive maintenance and have a significantly shorter life span.
With so many flexible options, you can move your window and door configurations, add and remove an internal partition wall, turning your garden office in to a year round living space.

FAQ's
A steel-framed garden room is an outdoor structure built with a durable steel frame, designed to provide a versatile space in your garden. It can be used as a home office, gym, studio, or leisure space, offering a modern alternative to traditional wooden garden buildings.
Yes, most steel-framed garden rooms are insulated to provide year-round comfort. High-quality insulation can keep the space warm in winter and cool in summer, making it energy-efficient and suitable for use in all seasons.
Steel-framed garden rooms require screw pile foundations.
Steel frames offer several advantages, including:
- Durability: Steel is resistant to warping, rotting, and insect damage, ensuring long-lasting strength.
- Design Flexibility: Steel frames allow for larger openings, sleek designs, and custom layouts.
- Fire Resistance: Steel is non-combustible, providing extra safety.
- Low Maintenance: Minimal upkeep is required compared to wood, which can deteriorate over time.
No, you do not need steel for a garden room, but it is better. Timber frames have a shorter lifespan and require significantly more maintenance than steel frame garden rooms.
The strength of wooden frame garden rooms result in an inferior structure which, in the long term, can result in significant cost to the owner.
In many cases, garden rooms do not require planning permission if they meet certain size and placement conditions. However, this can vary based on location, the intended use of the room, and local regulations. It’s always best to check with your local planning authority or consult with your supplier.

With proper care and maintenance, steel-framed garden rooms will last a lifetime. Their resistance to common issues like rot, pests, and weather damage contributes to their long lifespan. We offer a 25 year guarantee on our steel frames.
Yes, you can have a toilet in a garden room.
Our garden rooms come with an option of plumbing to ensure that your building is equipped with the benefits of a toilet and other facilities where required.
Yes – it is worth building a garden room if you are looking to create space in an external, separate area.
Garden buildings have multiple uses that can be repurposed as required. They act as storage areas, office space, an art studio, posh shed (!), gyms, and pretty much everything in between.
When partitioned, they become multiroom buildings which can be configured and installed to spec. A steel frame garden room provides a strong, solid garden room that acts as an extension of the home.
No – Our light steel framing systems are manufactured using hot-dip galvanized (zinc-coated) steel, which prevents corrosion in normal building environments.
