Structural Construction Systems
Ground Screws, Steel Frames & Modular Build Systems
Modern garden rooms and modular buildings rely on engineered structural systems designed to deliver strength, speed of installation and long-term durability. This section explains the foundation and framing technologies used in modern modular construction.
This section explains the structural technologies used in modern modular construction, including ground screw foundations, steel frame structures and integrated building systems designed to eliminate traditional groundwork and reduce installation time. Forti Nova supplies structural systems across Lancashire, Manchester, Liverpool, Leeds and the wider North West, supporting homeowners, contractors and garden room manufacturers.
Ground Screw Foundations
Ground screws — sometimes called helical piles or screw piles — are a modern alternative to concrete foundations. Installed hydraulically into the ground, each screw creates a load-bearing anchor capable of supporting garden rooms, decking, modular buildings and lightweight structures.
Unlike traditional concrete, ground screws require no excavation, no formwork and no curing time — making them the preferred foundation system for modern modular construction.
- Excavation may be reduced on suitable sites
- No concrete curing stage where a screw design is suitable
- Programme confirmed after site and design checks
- Ground disturbance depends on the chosen method
- Sloping sites require measured design information
Steel Frame Structures
Light gauge galvanised steel frames provide a strong, dimensionally stable structural system for modern garden rooms and modular buildings. Unlike timber structures, steel frames are resistant to warping, rot and moisture movement, allowing faster installation and more precise construction.
Steel frame systems are widely used in modern modular construction across Europe and are increasingly popular in the UK for garden rooms, home offices, modular extensions and commercial structures.
- Garden rooms & garden offices
- Home offices & studios
- Modular extensions
- Commercial modular buildings
