With a design and management background in the construction industry, we work with a critically regionalist philosophy.


This approach also include other fundamental design deliverables such as tradition, environmental impact, feasibility and a deep understanding of spatial psychology.

We are always relentless in exploring new design narratives and offering progressive architectural ideas and solutions.

I am an adventurous architect on a mission to do awesome projects with interesting people all over the world.

Thank you for taking the time to scan through my website. I hope you saw something you liked.


I created JACOSTUDIO to connect me with interesting people all over the world, for unusual project collaborations and commissions.

I started off as a design office tea boy in 2004, after which i completed a Masters in Architecture qualification from NMMU in South Africa in 2010. Following this I worked in an award winning architecture firm in Namibia for a few years.

By 2015, I started the first Jaco Studio in South Africa. Since then  I have collaborated with, and consulted for, many other design firms and studios, whilst traveling to various corners of the earth.

I recently moved to Ljubljana to open a European branch of JACOSTUDIO.

Thus far the journey has been very challenging, but also fantastic.
