Here's a bit more about me

I started my career with a Diploma in Building Design at Bendigo TAFE and was lucky enough to land a position working for a leading building designer in Shepparton. Predominantly designing commercial office spaces for renowned developers, we also focused on shopping centres, schools, and hospitality spaces.
Gaining such a wealth of knowledge from local legends was a gift that later inspired a dream. So, in 2009, I relocated from The Murray to the Gold Coast with my husband, I started work with a local Gold Coast Design and Drafting Service, this is where I built my own reputation and rapport with local Builders and industry partners.
In 2014 life as I knew it changed with the birth of our first child, seeking a flexible work-life balance I knew the goal to one day start my own design business was the right next step.
BCG Building Design was then established in 2015.
Building a successful and highly sought-after company around raising children has been a profound blessing.
BCG Building Design has allowed me to conceptualise homes that exceed my client's expectations, bringing pride, happiness, and a sense of belonging while still allowing me to kick goals at home!
Raising three little ones, I understand the importance of creating memories and having a space where form meets function; design meets warmth, organic flow, and space creates rest, ease and relaxation, meaning that your dream becomes more than just a house.
In the age of Pinterest and Instagram, it's easy to get caught up in current trends, so knowing how to take those ideas and turn them into a design that endures takes thought, understanding, care and skill.
I am passionate about timeless design, original ideas yet simple and elegant.

“Bianca carefully took into consideration the position of our home on the plot to ensure that the aspect from each elevation was maximised and the front facade had beautiful street appeal.

Being the first time we have built a home, Bianca guided us through each step of the design and approvals process, which we really appreciated.”
