Our work reflects specialist expertise in steel frame construction, SFS infill systems, and light gauge steel framing (LGSF) across a wide range of building types. Every project is evaluated through the utilisation of steel frame structures from both an engineering and architectural perspective, with a strong focus on creative, efficient solutions. This includes the development of new methods of steel frame design for connections, gravity systems, and lateral load–resisting systems, as well as advanced approaches to fire protection and blast performance.
We continually explore the aesthetic and visual impact of each structure, making innovative use of architecturally exposed structural steel while applying modern construction techniques such as panelised steel frame building, factory-assembled panels, and steel frame infill between concrete floors. Our capability extends to complex roof-top extensions, SFS rooftops, and steel frame rooftop structures, supported by expertise in steel skeleton frame construction and high-performance steel framing systems.
As a trusted SFS specialist sub-contractor and steel frame sub-contractor, we combine technical precision with architectural vision to deliver reliable, modern, and efficient solutions for clients across the UK.
Our SFS infill projects showcase the innovative use of steel frames infill between concrete floors, demonstrating precision in light gauge steel framing and efficient structural steel structures. Every steel frame building is evaluated for its architectural and engineering merits, with a focus on creative framing with steel, connections, and lateral load resisting systems. The steel frame sub-contractor team applies advanced SFS construction methods, ensuring fire protection, blast resilience, and visual impact are optimised. From roof top extensions to SFS rooftops, our projects illustrate the versatility of metal frame buildings and steel skeleton frame construction. By integrating steel substructure and frame steel structures, each steel frame home or building with steel frame benefits from durability, speed of construction, and aesthetic excellence. Specialists in SFS infill consistently deliver high-performance steel framed buildings tailored to modern architectural demands.
Forts Group High-Rise Rooftop Extension Following the successful delivery of Albany Court, Forts Group once again entrusted BAS Frames to construct another rooftop extension—this time comprising 8 flats on top of an existing 6-storey building.

Project Challenges and Site Constraints The nature of the stick-build approach was […]
Case Study: Fulham Imperial Road – GAS Depot The Fulham Imperial Road project presented a unique challenge due to its history as a former gas depot. While the entire site was acquired and managed by St. William, the construction of the GAS depot itself was awarded to Erith, one of Europe’s leading demolition contractors. This […]
The 56 Chatfield Road project presented unique challenges compared to other projects, such as the GAS Depot. Project Context: Riverside Residential Extension While similar in some ways, it was notably different due to its residential nature, being situated on the picturesque River Thames, and the complexity of adding four additional storeys to an existing building. […]
Technical Installation of High-Rise SFS Infill System This project presented a unique and complex challenge in terms of installation. Our team was appointed to complete the installation and fully manage the on-site works for this advanced infill system in partnership with Steel Frame Solutions. The scope of works included: Installing insulation between the studs, Fitting […]
Hathaway House: 14-Storey Mixed-Use SFS Infill The Hathaway House project, completed in 2018 for HG Construction, was a complex and rewarding scheme involving an infill system package that included boarding, vent formation, and brick tie channels. The development featured a 14-storey mixed-use tower combining residential and commercial spaces, alongside a 4-storey office building, and was situated near Paddington Station. Overcoming Paddington High Street Logistics […]
Kindergarten Construction Finchley In 2018, we completed a kindergarten project in Finchley, delivering high-quality results on time and within budget. The main structure of the building was constructed using Hot Rolled Steel (HRS), while our team expertly formed the external walls and window openings with Steel Frame Systems (SFS). HRS and SFS Infill System Delivered in Under 3 […]
Our panelised steel frame buildings reflect the future of LGSF (light gauge steel frame) construction. Using factory assembled panels for rapid and precise installation, these steel frame structures excel in both structural integrity and visual design. Every project demonstrates innovation in frame steel systems, steel frame wall connections, and roof top extensions, while optimising steel construction efficiency. The panelised LGSF method supports steel framed houses, metal frame homes, and industrial metal buildings, allowing faster build times with reduced on-site disruption. Our SFS specialist sub-contractor teams ensure steel framework construction aligns with architectural vision while maintaining robust steel skeleton frames. Whether steel frame garden rooms or steel frame storage buildings, the combination of metal frame structures and steel framing systems offers strength, precision, and design flexibility. These steel frame building kits showcase modern steel frame building construction techniques with attention to every structural and aesthetic detail.
Perrymount Road: 8-Storey Standalone SFS Full Build The Perrymount Road project is an ambitious and innovative undertaking. As an 8-storey full-build structure, it stands as one of the tallest standalone buildings completed using Steel Frame Systems (SFS) exclusively. This project will be entirely factory-assembled, with panels delivered directly to the site for rapid assembly. Given […]
Our steel frame stick build projects focus on bespoke steel frame homes and industrial steel buildings using traditional frame of steel methods combined with modern SFS construction. Each steel framed building is evaluated for structural efficiency, fire protection, and lateral load resisting systems, while maximising aesthetic impact. Our steel frame sub-contractor teams specialise in stick build steel frame construction, steel frame rooftop extensions, and metal building frame kits, ensuring both steel framework and steel skeleton frame align with architectural design. Stick build methods provide flexibility for steel frame barns, metal frame houses, and light gauge steel frame buildings, delivering durability, speed, and precision. Every steel structure building showcases innovative steel construction techniques, highlighting the advantages of framing with steel in steel frame building construction. From steel frame storage buildings to steel frame sheds, our projects demonstrate the versatility and reliability of steel framed houses UK and building with steel frame systems.
7-Storey SFS Full Build for Croydon Council In 2021, we successfully completed a 7-storey full build system for Selsdon Contractors, in partnership with Steel Frame Solutions. The project comprised 54 flats built for Croydon Council, replacing seven detached houses near Purley Station. Our scope of work included the SFS full build system, flooring, boarding, breather membrane installation, and brick tie channels. Despite the challenges, […]
