A garden office, unlike a shed or summerhouse, is built in much the same way as a modern house. At their core, most use conventional timber frame construction or, more recently, Structural Insulated Panels (SIPs). There is an emerging trend to steel frame garden office to build. Because the construction sector is adopting new techniques.

This article explores what a Steel frame garden office, the pros and cons, and whether it is a better alternative to a timber frame.

Trend: garden offices, what real estate investors need to know

Garden offices typically use wooden beams to form a load-bearing frame. A steel garden room uses light galvanised steel instead of wooden beams.

There are certainly advantages to steel frame construction, such as strength and speed of assembly, but there are also disadvantages. Read on for an unbiased look at the pros and cons.

Er zijn tal van voordelen verbonden aan het kiezen voor een tuinkantoor met een staalframe. Hier zijn enkele van de belangrijkste aspecten: * **Duurzaamheid en levensduur:** Staal is een uitzonderlijk sterk en robuust materiaal. Een staalframe tuinkantoor is daardoor bestand tegen de tand des tijds, weersinvloeden zoals wind en regen, en is minder vatbaar voor rotting, ongedierte of vervorming in vergelijking met hout. Dit resulteert in een aanzienlijk langere levensduur en minder onderhoud op de lange termijn. * **Sterkte en stabiliteit:** Het staalframe biedt een uitstekende structurele integriteit. Dit betekent dat het tuinkantoor zeer stabiel zal zijn, zelfs onder zware belastingen of in winderige omstandigheden. Dit is essentieel voor een veilige en comfortabele werkruimte. * **Ontwerpmogelijkheden:** Staal kan met grote precisie worden geproduceerd, wat resulteert in strakke lijnen en moderne esthetiek. Dit maakt staalframe tuinkantoren ideaal voor een eigentijdse uitstraling. Bovendien maakt de sterkte van staal het mogelijk om grotere overspanningen te creëren zonder dat er veel interne ondersteuning nodig is, wat kan leiden tot meer open en flexibele interieurruimtes. * **Brandwerendheid:** Staal is van nature niet brandbaar, wat bijdraagt aan een verhoogde veiligheid van uw tuinkantoor, vooral als het bijvoorbeeld in de buurt van andere gebouwen of potentieel brandbare materialen staat. * **Milieuvriendelijkheid (recycling):** Staal is een volledig recyclebaar materiaal. Dit betekent dat bij de productie veel gerecycled staal kan worden gebruikt, en aan het einde van de levensduur van het tuinkantoor kan het staalframe opnieuw worden gerecycled. Dit maakt het een duurzame keuze met een lagere ecologische voetafdruk. * **Weerbestendigheid:** Staal is bestand tegen verschillende weersomstandigheden. Mits correct behandeld tegen roest, hoeft u zich geen zorgen te maken over rot, kromtrekken of aantasting door insecten zoals bij hout het geval kan zijn. * **Snelle montage:** Voorgemaakte stalen componenten kunnen vaak relatief snel en efficiënt worden gemonteerd, wat kan leiden tot een kortere bouwtijd in vergelijking met traditionele methoden. Hoewel staalframe tuinkantoren doorgaans zeer efficiënt zijn en weinig onderhoud vergen, is het belangrijk om te zorgen voor een goede afwerking en isolatie om het comfort van een werkruimte te garanderen.

Steel frames They may well be a new technique in the construction of garden offices, but they have been a key component of architectural design for decades. Below are some of the reasons why metal frames are becoming increasingly popular amongst suppliers of garden offices.

Strength

Although wood is a strong building material, it cannot compete with steel. Light gauge steel, also known as cold-formed steel, is much lighter and stronger than wood of equal dimensions.

Installation speed

Metal frames are designed and manufactured entirely on site and only need to be assembled on arrival. They are also lightweight, making them easier to transport and handle. In practice, the structural work can be completed in a matter of hours rather than days.

Faster assembly means not only less disruption during the construction phase, but also lower labour costs. While labour costs may seem like a concern for the supplier, they are ultimately accounted for in the project and affect the final price.

Long-term

Simple, sturdy and reliable – a metal frame does not suffer from the same rotting, warping, splitting and cracking over time as a wooden frame. Steel frames are also not susceptible to pests or insects.

Accuracy

We have already mentioned that galvanised steel frames are designed and manufactured in the factory. Suppliers use computer-aided design (CAD) tools for planning the framework. Structural calculations ensure that the proposed garden room is sturdy and durable. Computer-aided manufacturing (CAM) then translates these plans into a prefabricated structure with an accuracy of up to 0.5 mm.

Timber-frame construction, on the other hand, is measured and cut on site. Although the planning involved in timber-frame construction is the same, it is by its very nature less precise.

Costs

We've already mentioned labour costs, but that's just one way steel frame construction can compete with timber frame construction.

It is no secret that timber prices in the UK have skyrocketed since the first lockdown in March 2020. Few people outside the construction sector are aware of the extent of these price rises. Like all building materials, steel has also gone up in price, but not to the same extent as timber. The price of timber has more than doubled, and with ongoing shortages in 2022, that trend is unlikely to reverse any time soon.

Apart from the cost of raw materials, steel produces less waste. Don’t forget that you pay twice for waste: firstly, in the cost of the unused material, and secondly, for the bin to dispose of it.

What are the disadvantages of a steel-framed garden office?

Given all the advantages we’ve highlighted, you might be wondering what the catch is. As is often the case, there are trade-offs to consider. We’re now going to look at the disadvantages of a steel-framed garden office.

Fire resistance

Many people will be surprised to see that fire resistance is a disadvantage of steel-frame construction. We have even seen some suppliers view the fact that steel does not burn as an advantage over timber construction. Steel is indeed incombustible, but unlike timber, its structural integrity is quickly compromised by heat.

A fire can expose the steel frame to enough heat to cause it to collapse.

Will a steel-framed garden office rust?

Steel does not rot like wood, but it can rust if it comes into contact with moisture. Builders could opt for stainless steel because it does not rust, but this is often prohibitively expensive. Instead, manufacturers opt for galvanised steel.

Galvanising is the process of coating steel with a layer of zinc. Zinc adheres well to steel and prevents water and oxygen from reaching the underlying metal. Although galvanised steel lasts for decades in most circumstances, there are factors that can accelerate its deterioration, such as:

• Excessively damp environments – usually not a problem in the United Kingdom
• Environmental conditions – high levels of salt in the air
• Contact with strong alkalis such as plaster or cement

Is a steel frame garden room durable?

Both steel and timber suppliers will highlight their environmental credentials. All in all, it is a difficult subject to assess.

Steel, an alloy of iron, is mined from the earth and undergoes an energy-intensive production process. Wood, on the other hand, is a renewable resource when harvested responsibly. But there is more to their environmental credentials than that. Steel is fully recyclable; it can be remelted and reused repeatedly without any loss of quality. Most conservatories with steel frames use a high percentage of recycled steel. It is possible to recycle wood, but not to the same extent.

Although steel is one of the most sustainable Compared to metal, wood is demonstrably the greener building material.

Summary – is a steel-framed garden office better than a wooden one?

Whatever the ultimate aim for your garden room or office, there are pros and cons to both steel and timber frame construction. Steel is stronger, but it is also more susceptible to condensation. A steel frame can be a good option, but suppliers must ensure that no thermal bridges form.
