Extension Vs Garden Room: How do they compare?

If you’re looking to add extra space to your home, you might be weighing up the options of a house extension or a garden room. Both options have their pros and cons, and ultimately the decision will depend on your personal circumstances and requirements. In this blog post, we’ll take a closer look at the benefits of building a garden room compared to a traditional extension.

Speed of Construction

One of the biggest advantages of building a garden room is the speed of construction. Unlike traditional extensions, which can take several months to complete, garden rooms can be built in a matter of weeks. This is because our garden rooms are made from timber frame or SIPs construction, which takes a fraction of the time it takes to build in masonry.

Cost per m2

Another advantage of garden rooms is their cost per m2. Generally, garden rooms are a more cost-effective solution compared to extensions. This is because extensions require more materials and labour, and may also require expensive building regulation approval.

Reduced Embedded Carbon

Garden rooms also have a lower embedded carbon footprint than traditional extensions. This is because the materials used in garden room construction are often sustainable and eco-friendly, reducing their impact on the environment. By installing a garden room which a green roof at the end of your garden, you can actually increase biodiversity in the garden.

Sustainable Materials

Garden rooms can be built using a range of sustainable materials, such as natural wood, bamboo, and recycled materials. This not only reduces their environmental impact but also creates a more natural and calming environment, perfect for relaxing or working from home.

No Need for Building Regulation Approval

One of the biggest advantages of garden rooms over extensions is that they do not require building regulation approval. This means that you do not need to pay for inspection fees or engineer’s drawings, making the process more cost-effective and straightforward.

In conclusion, while extensions can be a good option for some families, garden rooms are an excellent alternative for those who want to add extra space to their home without the expense and hassle of a traditional extension. With their speed of construction, cost-effectiveness, reduced environmental impact, and flexibility, garden rooms are a fantastic way to maximise the potential of your outdoor space.

Building a garden room is a less disruptive option compared to a traditional extension, which can cause a lot of upheaval and disruption to family life. Unlike extensions, which can involve noisy and dusty building work taking place inside your home, garden rooms are built outside, in your garden. This means that you can go about your daily routine without being disturbed by the construction process.
