Two-Storey Steel Structure Extension

The owner needed more usable area at the rear without disturbing the existing building. Structural steel was the right answer — lighter than concrete, so it transfers less load into the original foundations, and faster to erect on a tight site.

We began by surveying the existing structure, calculating the imposed loads and designing independent footings, then produced a complete structural set — column and beam layouts, elevations, sections and connection details — so the alteration permit could be filed correctly. The ground level provides parking for two cars; the upper level adds usable floor area reached by an external steel stair.
