Who We Are
Perfect Square Design derives its name from the Fibonacci mathematical equation that is the product of two equal integers or factors. The secret and result to a GREAT design company is weighed on two things
Experience and Passion.
Our Director Gilbert Sayegh and our design team have a combined 25 years of local experience working on a range of project scopes – no job is too big or small.
Throughout the ages, the greatest minds sought to understand the principles and mathematical order of the universe. What they discovered was that every geometric shape, every animal, flower, shell, or great structure can be defined by and follow a strict set of rules.
We are Sydney based but work with clients across Australia. Our building designers and engineers work closely with trusted industry consultants to make it easy for our clients to develop their dream design and see it come to life. No matter what the problem we believe there is always a solution.
Perfect Square Design gives tribute to these wonders and understands the value that nature and law have over quality in architecture. Our design philosophy is centred on systems of harmony and proportion. Le Corbusier, one of the pioneers of modern architecture explains this in the following way:
We are passionate about creating environments that enable people to live their best lives and achieve their greatest potential. Our goal is to improve quality of life for people through better design.
Thus comes our passion for perfection in everything we do. We believe that every space – no matter the scale – deserves the quality, proportion and harmony they deserve.
