Our story
Who We Areand Who We Help
ISF Systems Limited is a light gauge steel frame (LGSF) construction company based at 48 West George Street, Glasgow. We build extensions, garden rooms, offices, classrooms and commercial units for homeowners, businesses, schools and public sector clients.
What we specialise in
Our core work is steel frame construction, delivered either as the frame alone or as a full turnkey building. Because we also provide electrical, roofing, joinery and plastering, we can take a project from survey and design right through to a finished, fitted-out space. See all our services.
Depth of experience
Design is carried out in-house, and we work alongside architects and structural engineers where a project needs them. That means the frame, the planning drawings and the trades are all coordinated from the start, rather than fixed on site later.
Where we work
Based in Glasgow, we work UK-wide including Northern Ireland: Glasgow, Lanarkshire, Edinburgh, Stirling, Aberdeen, Newcastle upon Tyne, Manchester, Cardiff, Belfast.
