OffPOD is the first residential construction company in the UK to utilise groundscrews for our modular extensions. Groundscrews are an innovative and sustainable alternative to traditional foundation systems. They offer significant time-saving benefits, superior load-bearing capacity, and a more eco-friendly construction method. Let's explore why groundscrews are the smart choice for your next building project.

Time-Saving Advantages:


  • Quick Installation: Groundscrews can be installed in a fraction of the time it takes to pour a traditional concrete foundation. There's no need for excavation, formwork, or waiting for concrete to cure. This means your project timeline can be significantly reduced, saving you both time and money.


  • All-Weather Installation: Unlike concrete foundations, groundscrews can be installed in virtually any weather conditions. Rain, snow, or freezing temperatures won't delay your project when you choose groundscrews.


  • Immediate Load-Bearing Capacity: Groundscrews provide immediate load-bearing capacity, allowing for the construction process to continue without waiting for the foundation to settle or cure.

Groundscrews: Faster, Cleaner & More Sustainable Foundation Installations

Superior Load-Bearing Capacity:


  • Versatility: Groundscrews are available in various sizes and capacities to suit a wide range of projects, from residential to commercial and industrial applications.


  • Strong and Stable: The helical design of groundscrews allows them to penetrate deep into the ground, providing a stable and secure foundation that resists uplift and lateral loads.

  • Adjustable and Adaptable: Groundscrews can be easily adjusted or repositioned, ensuring a level and stable foundation even on sloping or uneven terrain.

Sustainability Benefits:


  • Reduced Environmental Impact: Groundscrews eliminate the need for excavation and concrete, significantly reducing the amount of construction waste and the impact on the surrounding environment.


  • Reusable and Recyclable: Groundscrews can be removed and reused in future projects, reducing the need for new materials and minimizing waste. They are also made from recyclable steel, further contributing to their eco-friendly advantages.


  • 70% Lower CO2 Emissions Per Sqm: By eliminating the need for concrete production and transportation, groundscrews help to reduce CO2 emissions associated with traditional foundation construction.

When you choose groundscrews for your next project, you're investing in a time-saving, cost-effective, and sustainable foundation solution. Their superior load-bearing capacity and adaptability make them the ideal choice for a wide range of construction projects. Embrace the future of foundation technology with groundscrews and build a stronger, more eco-friendly world.

Steel Frame for garden room extension

Why Use Steel?

The innovative use of steel as a building material in garden structures dates back to the construction of skyscrapers in 1883, and since then its popularity and use have only continued to grow. Steel is now a staple material in commercial construction due to its remarkable strengths and benefits. Steel is stronger, more durable, and has a longer lifespan than other traditional building materials, such as concrete. Additionally, steel is one of the most environmentally sustainable materials available as it is highly recyclable and helps conserve energy. By choosing OffPOD and our use of steel in our building frameworks, you are not only investing in a premium quality product, but also making a responsible choice for the environment


The use of steel frame construction in residential markets is quickly gaining popularity and recognition for its many benefits. The pre-fabrication of steel frames off-site and the option for modular or semi-modular construction significantly speeds up the building process. In fact, by choosing steel frame construction with OffPOD,  you can expect your project to be completed up to 2-3 times faster than with traditional brick and mortar methods. This means less time waiting and more time enjoying your new and improved living space. 

Steel is a preferred material in construction due to its remarkable strength, longevity, and durability. It also boasts a lower carbon footprint compared to other building materials such as concrete, making it an eco-friendly option. Steel is also one of the most recyclable materials in existence, contributing to a sustainable future for our planet. At OffPO, we understand the importance of sustainable building practices and use steel frames in our modular extension projects to help reduce our impact on the environment.
