About

A small practice with a big CV.

Most of our work is sub-consulting for leading international engineering firms. We join their design teams on specific projects. Usually the hard parts.

That has put us on super tall towers, stadium roofs, fabric structures, cable nets and freeform gridshells. Far more than a practice our size would ever expect to see.

At home in South Africa we provide full structural services on commercial and residential buildings and other structures. We also provide specialist seismic analysis, FE analysis and peer reviews for other consultants.

We thrive in the early stages of design. Developing concepts, testing structural options and producing clear 3D material for design reviews and competitions is where we add the most value.

Our workflow runs fluently across multiple software packages and links seamlessly into AI, so we can test, interrogate and optimise a design quickly.

Concepts and competitions

Clear structural thinking while the design is still evolving.

Approach

From concept to detailed design.

We'd rather shape the structure than just make it work.

  1. Early input

    We add most value at concept and competition stage, while the structure is still a design decision.

  2. Parallel analysis

    Sofistik, Strand7 and Robot. Key results are checked in more than one package.

  3. Geometry

    Rhino and Grasshopper for complex and parametric forms, linked straight into analysis.

  4. Computation

    Scripting and AI tools let us test more options, faster. That leaves more time to review and improve the design.

  5. In 3D

    Clear visuals that clients and contractors understand at a glance.

  6. On the record

    Every input and output documented, step by step.

Matthew Grey

BScEng (UCT) · MSc (Oxon) · PrEng · MSAICE

An engineer drawn to creative, architectural structures. Matthew did his MSc at Oxford on the seismic behaviour of guyed masts, then spent four years at Buro Happold in London on a variety of projects, including numerous towers in the Middle East.

Back in Cape Town he worked in marine engineering at ZAA and tensile architecture at Tension Structures before co-founding Shape in 2013.
