House structural design
Structural design for new homes, extensions, second storeys and renovations. This is the work we do most often, for owners, architects, building designers and builders.
- Footings and slabs, including sloping and reactive sites
- Timber and steel framing, beams, lintels and bracing
- Wall removals and openings in existing homes
- Decks, pergolas, retaining walls and pools
- Computations and drawings for your building surveyor
- A 3D model of the structure, so you can check it against the design
Commercial and corporate

- Structural design in steel, concrete and timber
- Alterations and fit-outs in existing buildings
- Mezzanines, platforms and equipment supports
- Coordinated 3D models for design teams and builders
- Site civil and drainage for the same project, if needed
