About Us

Coastal Hamptons Design Studio is a boutique interior design studio located in the South Sydney suburb of Sans Souci. An avid renovator, Allie Duval started transforming homes in 2009 when she and her husband, Hedley purchased their first investment property in Western Sydney. What started as an interest in improving property resulted in multiple renovations and eventually renovating their own home.

With a keen eye for detail, the Duval's renovation of their own property resulted in a Daily Telegraph feature article highlighting their beautiful transformation. This led Allie to be inspired to create homes and work with clients to help them bring their design ideas to life. Allie’s design mantra is to “Create the home you were meant to live in today and you will still want to live their tomorrow”. Allie believes our home represents who we are and reflects our lifestyle.  Coastal Hamptons Design Studio is here to help you create your space, a true reflection of who you are with the things you love.

Client Testimonials

I used Coastal Hamptons Design Studio for design and style guidance on my new apartment. Allie was great. She was very responsive with quick turn around times and offered some great suggestions. I really appreciated the way she organised things such as quotes and swatches and followed up on deliveries. The real challenge came when one week before I moved in I discovered I needed new carpet - in the middle of COVID lock-down. Allie was wonderful. She tapped her network, got the quote and installation organised and helped me with the colour choice. Can't thank her enough for all she did for me.Read More

Allie was amazing in helping us with our cabana redesign. Allie went over and beyond to help with recommendations, arranging samples, quotes and ensuring we had what we need to implement the agreement design. I saved a lot of time as I did not need to run around. But overall Allie understood my brief and delivered a very real concept that we can build.Read More

Allie was a pleasure to deal with and would be happy to recommend to anyone. I always found Allie a great communicator and I was wrapped with the design she put together for me. Thanks Allie.Read More

Allie was such a pleasure to work with. Asked lots of questions to have a clear understanding of what was in my head and how I wanted the space to make me feel. It was so much fun having someone to bounce ideas and also shift me back on track. Sometimes less is more! Thank you again for this amazing experienceRead More
