She has worked with high-end projects spanning residential, retail, commercial and hospitality sectors.

Teresa resides in the Eastern Suburbs with her husband. Outside of her design work, she enjoys staying active outdoors and spending time with family and friends. Her favourite activities include travelling, bouldering, yoga and pilates, which help her stay both mentally sharp and creatively inspired.

  • I was initially reluctant to engage an interior designer for my new kitchen as did not feel it was needed. However, Teresa incorporated and expanded my initial ideas to a new level of design and sophistication. Highly talented with exceptional attention to detail, Teresa assisted me throughout the entire process. The final design was stunning and exceeded all expectations. Teresa is also at the forefront in style, design and colours. I therefore highly recommend Teresa for any project and look forward to engaging her services again for my next renovation.”
