Size and Design: The size of your garden room significantly impacts costs with larger structures require more materials and labour. Design complexity, such as bespoke shapes or intricate architectural features, can also contribute to increased costs.

Average Cost Per Square Meter: One way to estimate costs is by looking at the average cost per square meter of construction. In the UK, this can vary based on factors like location, materials, and customisation. As of 2023, the average cost per square meter for building work in the UK ranges from £4000. This is why many people are looking at a garden room for an alternative to big construction bills. The price range for a steel framed garden room is between £1000- £2500 per sqm.

Interior Upgrades: Beyond construction costs, it’s crucial to budget for any additional interior upgrades you may wish to include.  This can range from adding air conditioning to a feature wall with designer wallpaper.

screw pile foundations

When building a steel framed garden room the preferred foundations are screw piles.

Screw pile foundations, also known as helical piles or screw anchors, offer several benefits in various construction applications due to their innovative design and installation process. Here are some key advantages:

Ease of Installation: Screw piles are installed using hydraulic equipment, making the process relatively quick and straightforward. The absence of concrete curing time allows for immediate construction or loading, reducing project timelines.

Minimal Site Disturbance: The installation of screw pile foundations generates minimal disturbance to the construction site compared to traditional methods like concrete foundations. This is particularly advantageous in environmentally sensitive areas or locations with limited access.

Versatility: Screw piles are versatile and suitable for various soil conditions, including clay, sand, and gravel. Their adaptability makes them a practical choice for a wide range of applications, from residential buildings to infrastructure projects.

Cost-Effective: The overall cost of screw pile foundations can be competitive, especially when considering reduced labour, equipment, and material costs associated with traditional foundation methods. The quick installation also contributes to cost savings.

No Excavation or Spoils: Unlike traditional foundations that require excavation and removal of soil (spoils), screw piles do not generate excess soil. This reduces the need for soil disposal and associated costs.

Immediate Load-Bearing Capacity: Screw piles can bear loads immediately after installation which is beneficial in projects where time is a critical factor, as it eliminates the waiting time associated with curing concrete in traditional foundations.

Environmentally Friendly: The minimal site disturbance, lack of excavation, and potential for reusing screw piles in other projects make them an environmentally friendly foundation option. They are particularly suitable for areas with sensitive ecosystems.

Year-Round Installation: Screw piles can be installed throughout the year, including in cold weather conditions. The absence of curing time allows for construction in seasons when traditional foundation work might be challenging.

High Load Capacity: Screw piles offer excellent load-bearing capacity, making them suitable for supporting various structures, including residential homes, light commercial buildings, telecommunications towers, and more.
