Structural engineering for Southampton homes and small commercial projects
Southampton has a diverse building stock: older terraces, post-war housing, and modern developments near the waterfront. Typical structural queries include open-plan wall removals, steel beam design and bearings onto masonry, chimney breast alterations, and extension steelwork coordinated with architectural layouts.
We keep deliverables practical: clear assumptions, buildable details, and drawings that builders can follow — while keeping Building Regulations compliance front and centre.
1) Internal alterations (open-plan living)
Removing or widening openings in load-bearing walls, installing steel beams, posts, and padstones, and checking bearings and stability.
- Beam sizing + connection notes
- Padstone / bearing checks
- Temporary works guidance (high-level)
2) Extensions & renovations
Rear/side/wraparound extensions, structural tie-ins to existing houses, and details for steelwork, lintels, and supporting walls.
- Load paths + member sizing
- Opening/lintel design
- Coordination with architect layouts
3) Loft conversions
Dormers, ridge beams, floor upgrades, and trimming around stair openings — keeping headroom and buildability in mind.
- Floor joist / beam design
- Support to existing structure
- Notes for builder sequencing
