It’s an instinctive human trait to be interested in how things are made, why they are the way they are and what makes them work.

In this article, we want to bring you closer to knowing your garden room. We will discuss the intricate details of the materials and structure of your new life-changing space, hopefully providing you with all the necessary information and expanding your knowledge on how your garden room is put together.

The Structure

Firstly, let’s look at the most important aspect of any dwelling – the structure. Your garden room is made from something called SIPs. This stands for Structural Insulated Panels and they are highly revered as the building material of the 21st century.

These panels consist of an insulating foam core that is sandwiched between two structural facings. The facings are made from OSB or Oriented Strand Board. Versatile and durable, this is similar to particle board and is formed by combining adhesives and layers of wood strands, in particular orientations. SIPs are manufactured under stringent factory-controlled conditions and can be fabricated to fit nearly any building design. The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs is known to save time, money and labour.

SIPs panels further benefit the user by also requiring smaller heating and cooling systems, providing even more cost savings. As there are no VOC (volatile organic compounds) and the foam core is so air-tight, this enables perfect control of the indoor air quality.

The Materials

All of the materials we source and use for your new life-changing space, are tested and certified to the highest standards. Let’s delve further, in summary, into the other aspects of your new garden room;


There are four main solutions that we provide, for the most efficient and robust footing option for your new space. These are typically ground screws, concrete slab, concrete pads and jack pad footings. The optimum choice will depend upon the imposed loadings, the ground conditions and any other demands specific to your project.


In most cases, your garden room’s floor structure will be made from SIPs. The internal flooring is your personal preference, you can choose from a large array of laminate, natural wood, vinyl, rubberised or carpet.

Luxury garden building

Outer Walls

The outer facing of your garden room can be clad in many different finishes. These range from the maintenance-free Western Red Cedar, to alternative timbers, steel sheeting and even stone or slate. It is extremely important to us that you are happy with the aesthetic finish and that your neighbours have something nice to look at!

Windows and Doors

An ever-evolving component of the materials available, these are always improving and offering greater choice. From French-casement, bi-fold, sliding curtain walls, to name but a few. We can include specific features such as sun-reflecting coatings, integrated blinds and a choice of frame colour.


SIPs make up the main part of the roofing. Most of our flat rooves are covered in a single piece of EPDM (Ethylene Polypropylene Diene Monomer). This is a thick rubberised sheet, manufactured by Firestone. This material provides a permanent and excellent quality roof covering. Other roof types, such as slightly sloped or pitched, can also have Sedum tops. A newer and increasingly popular choice, Sedum is a low-maintenance layer of vegetation and living plants.

A light-weight alternative to Sedum roofing is artificial grass. This gives a softer appearance with less cost and weight.

Electrical fittings and Control systems

Modern LED units provide efficient and stylish lighting opportunities. At Swift we go a step further and use Collingwood H2Pro fittings. Their high-end finish and 7 year warranty speak volumes about the quality. Importantly, their slim profile enables us to maximise internal ceiling height, without compromising the insulation. As an option, all lighting can be controlled remotely if required.

A wide choice of heating and cooling systems will suit your specific needs and will be fitted as part of the installation process. What else could you dream of to add those touches that make all the difference? Maybe surround sound speakers serving a wall mounted TV with concealed cabling?
…perhaps mood lighting?
…possibly a feature wall with weather timber panelling?

You choose – and we listen!

We hope this article has provided you with a closer insight into the myriad options available, to create a truly unique life-changing space and ensure full enjoyment of your garden room for decades to come.
