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. Mission & standards ## How We Buildand What You Can Expect Our aim is simple: a building that is straight, strong and finished on the programme agreed in your quote, with no surprises along the way. ### Precision-made frames Cold-formed galvanised steel sections made to size, so walls go up straight and stay straight. No rot, warping or shrinkage. ### One team, one point of contact Design, planning, frame, trades and fit-out handled by ISF, so you are not chasing separate contractors. ### Planning & building control handled We handle planning applications and building control sign-off on your behalf, working with architects and structural engineers where needed. ### Clear, written quotes Every project starts with a site survey and a written quote setting out scope and programme before any work begins.
