If you are in looking to invest in a new garden room then there are a couple of things to consider before you start parting with your hard-earned cash; How long do I want my garden room to last, is this a long-term investment? If it is a long-term investment, will I require the ability to relocate my garden room due to reappointing the garden or moving home? If the answer is yes to the above, then you need to question what materials your garden room is made from? Will it withstand, or is it possible to even perform a relocation and what is its potential life span?

This article will sum up as to why it is worthwhile investing in a steel-framed garden room if any of the above is important to you.

If you are currently in the market for buying insulated garden rooms, whether it be to create beautiful home offices in the garden or for entertaining, then you will find yourself spoilt for choice with all of the options out there. Let’s face it, this isn’t a low-value item so it seems logical that you buy something which is enduring and will stand the test of time. Timber-framed garden rooms are up to the job but steel-framed garden rooms will outperform in all areas. Wooden frames are susceptible to wood rot which if left untreated can lead to a reduction in the structural integrity of the building. Rot can be caused by a number of issues and may not always be visible to address. A common occurrence with timber frames is for a small invisible leak to go untreated which over a prolonged period of time will lead to it rotting. With our galvanised steel frames this is not a concern.

The reason why the majority of garden room manufacturers do not use steel is down to the cost. A steel frame will typically cost 15% more than its wooden alternative. Here at OffPOD Modular Extensions & Garden Annexes, we refuse to make any compromise regarding the quality of the materials we use hence we ONLY use steel framed construction (SFC) for all of our Garden Room frames; with minimal care and upkeep of our OffPOD luxury garden rooms or granny annexes will still be standing long after we are gone!

If limiting the negative impact on the environment is of great importance to you then steel just about edges it in this area too! Wood requires the cutting down of trees, which is a major issue considering the mass deforestation taking place across the globe. This is destroying the natural habitats of both humans and animals, pushing the latter closer towards extinction. However, wood is generally considered a renewable resource when it is harvested from sustainably managed forests. Wood also traps carbon thus reducing the impact of the burning of fossil fuels. So the more trees we plant to serve our need for building materials, the more carbon those trees store and the buildings themselves store. Steel, from a structural point of view, is far more recyclable than wood and lasts a lot longer. This becomes particularly apparent when it comes to our OffPOD garden offices as one of the unique strengths with our use of steel frames is that the buildings are portable. They can be assembled and disassembled without negative affecting their structural integrity, ultimately making them recyclable. This means that if you were to invest in one of our garden rooms and move home then you would be able to disassemble your garden room and take it with you or, due to it being made from steel and having lasting structural integrity, you could sell it with your existing home adding to your home’s value.

Our modular build system coupled with the use of steel framed garden rooms means that our time at your property and the amount of mess produced is a fraction of that in comparison to what it would be if utilising traditional build methods and timber. Our steel frames are ordered based on our customers’ bespoke garden room or home extension designs. Steel frame construction is a design-led process, meaning that the need for skill to construct the building is more in the design stage and is carried out in our Burton On Trent Facility rather than on-site. Our approach leads to reduced engineering design costs and increased accuracy of the build which minimises errors and time on-site. Then it comes to your installation everything is already perfectly cut to size meaning that your unique Garden Room can be installed in one day. This is an innovative approach which is not utilised by many other companies who opt for a more traditional Garden Room installation.

You may have heard that using a steel frame construction rather than a wooden one can be extremely costly; this is where OffPOD Modular Extensions & Garden Annexes are different and are bringing about a real change to the industry. Due to our unique business model and modular build system, we have been able to keep our overheads to an absolute minimum and pass the savings on to our valuable customers. This means that if you were to look at a similar or lower specification Garden Room with the likes of Green Retreats or The Garden Office you will find you will save £1000’s if you decide to purchase with us as well as getting a Steel Framed Construction rather than a timber alternative. We are able to offer you a steel frame constructed Garden Room for less than what you would expect to pay for a timber alternative!
