Ground Screws: An Environmentally Friendly Alternative to Concrete

At Outside In Garden Rooms, we are committed to delivering high quality, durable garden rooms - all whilst being respectful of the environment.

From the base up, we have made environmentally friendly choices wherever possible. As standard, each of our garden rooms is clad in responsibly sourced FSC Siberian Larch, fully insulated and built with double glazed windows and doors. We source all of our materials from local suppliers to minimise travel and to help reduce carbon emissions. Where possible, we also use ground screw foundations which are an eco-friendly alternative to concrete.

Environmental Benefits of Ground Screws

No More DiggingEach of our builds begin with a strong, level foundation; formed through the use of ground screws where possible. We work alongside ground screw experts No More Digging who work in collaboration with Radix Base Systems to develop a system which uses fewer resources and provides a low carbon replacement for concrete.


Our partnership with No More Digging means that we can build garden room foundations with minimal impact, damage or disruption to the environment.

Did you know that:

  • Concrete is the 2nd highest consumed substance on Earth after water?

  • 3 tonnes of concrete is used on average by every person on the planet per year?

  • 10% of carbon emissions are a result of global cement production?

Other Advantages

Ground screws offer many other benefits over concrete, including:

No Disruption to your Garden

Rather than digging the land to make it flat, ground screw foundations provide a solution to challenges such as hard-to-access areas and uneven or sloping ground. This means minimal impact to the ground and surrounding area, alongside reduced disposal and mess!

Ground Screws

Reduced Installation Time

In comparison to a traditional concrete foundation, ground screws save on time. In fact, it’s 70% faster to install than a concrete foundation which involves additional steps such as excavation, formwork and hardening.

Year-Round Installation

In a country that experiences up to 250 days of rainfall each year, it’s especially important that the foundation can be installed all year round, no matter what the weather conditions. On the other hand, if concrete were to be poured in the rain, it may be compromised.

Strong, Long-lasting Foundations

Each screw is made from strong, structural steel and is weather-proofed for long-lasting protection and life expectancy. On top of each screw sits a standard or bespoke bracket which the floor joists can be added to.

At Outside In Garden Rooms, we install the foundations for clients as part of all builds. Once the ground screws are installed, the base frame is fixed in place to create the foundation of your garden room. From there, the rest of the installation process can take place.
