PJC + Partners — Est. 2004 · Cape Town
Sustainability | Performance | Comfort
Environmental performance consultancy shaping intelligent buildings, precincts and cities through climate-responsive design, advanced analysis and integrated systems thinking.
02 — Who We Are
Multidisciplinary practice
20+ years
A studio of architects, engineers, scientists and technologists translating climate, comfort and carbon into design decisions that can be built, maintained and afforded.
Our diversity is our strength. Scientific, engineering and architectural backgrounds bring a wide-angle perspective alongside a zoomed-in focus on the work itself.
We operate at the intersection of architecture and engineering — translators between disciplines, sense-makers between climate data and design intent.
Based in Cape Town, working across Africa and the Indian Ocean Islands. Founded 2004. Rebranded as PJC + Partners in 2018.

Pretoria05 — How We Think
An environmental design laboratory.
Systems thinking, iterative analysis, prototyping and testing. We model orientation, fabric, airflow, daylight and thermal comfort — then design against the results.
Every intervention is researched in-house, quantified against a commercial base case, and costed before we propose it. Plan B is always efficient.

07 — Why PJC
We work in a ZAR environment, not USD or EUR. We cannot buy our way out — we think our way out.
Technical integrators
Bridging architecture, engineering and science across the project life.
Translators
Making complex environmental data legible to design teams and clients.
Performance specialists
Quantified outcomes — energy, carbon, comfort and water — not slogans.
Environmental strategists
African context and realities, with globally benchmarked rigour.
