A ground screw system minimises disruptions to your property, as it often involves less noise, debris, and disturbance compared to traditional foundation construction.
A garden annex is a popular extension to increase the value of your home. These self-contained units can be used as a guest suite, home office or workshop. The granny annex is also a popular choice for multi-generational living.
Whatever your plans for your extra living space, high quality Ground Screws can help make them a reality. You can manage the construction of your garden annex from start to finish with the help of our Ground Screws for annexes. No more digging up your lawn or clearing trees to gain access. Ground Screws can be carried to the site and installed by hand, meaning access is rarely an issue.
The outdated method for building a garden annex would include digging deep excavations for the foundations and then filling them with concrete. Concrete can pollute nearby waterways and digging for the foundations can disrupt local wildlife and will create mess.
If you want to protect and preserve your garden while building your annex, Ground Screws can help you to achieve this goal. Ground Screws for annexes produce around 60% less CO2 than concrete, making it a greener and kinder choice that will limit damage to the surrounding areas.
Ground Screws present numerous advantages for annexes. Firstly, their rapid installation – often within hours – efficiently facilitates quicker occupancy. Secondly, they minimise site disturbance due to requiring no excavation compared to conventional foundations, which is particularly advantageous in residential areas where neighborly consideration is paramount.
Their versatility also enables installation across various soil types. Ground Screws are adjustable to ensure precise levelling, which will allow you to accommodate undulating ground or elevation changes. From an environmental perspective, they are highly favourable, generating far less carbon emissions during installation and offering reuse potential. Savings arise from reduced labour, no digging, no soil removal, and reduced working schedule. Lastly, their structural stability assures enduring support for annexes of diverse designs and sizes, ensuring their long-term integrity.
Due to planning permission requirements, structures that are used for living or short term stays will require Building Control Approval and Planning Permission. As part of our service, we provide a Site-Specific Compression Load Test on our Ground Screws which will prove the load capacity in the site soil conditions which will be aligned with the load requirements set by a structural engineer.
