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

If I could give 100 stars I would! Allie helped us with a complete double story renovation, exterior and interior styling. Allie is AMAZING! She has so much passion for what she does and it shows through her hard work and incredible eye for detail. I am totally in awe of her design abilities! She is so easy to work with and took so much time to understand our style and needs. She was able to take our ideas to a whole new level and bring me out of my comfort zone! I learnt so much from Allie, she was able to show me how to be a more adventurous with my styling which I’m so glad she did as it made such a difference to the end result! Allie had us on track and even ahead, ready for each new step. She is very enthusiastic and well organised which relieved us of so much stress. What I found so helpful is that Allie took the confusion out of choices, this was a big thing for me as I am a VERY indecisive person and I sometimes find making decisions a little overwhelming. Everything from samples, quotes, deliveries, follow ups and returns were taken care of, she even took me on personal shopping days and did numerous home visits! All in all I would say Allie was THE BEST investment we made through this whole journey, she became part of the family and I will forever be thankful for what she has helped us achieve!! XxRead More

No one like her!!Read More

I had the pleasure of working with Allie on a project of hers quite recently. My jaw hit the floor when I walked inside. The cohesion of each space throughout was perfection. I have worked with a lot of designers over the years and this is one of the highlights! I highly recommend Allie to anybody looking for that rare combination of natural talent, warmth and professionalism. Cheers Paul - Live by the Sea PhotographyRead More

We bought a new house end of Dec 2021 and engaged Allie from Coastal Hamptons Studio to help us renovate. I had a vision of what I wanted but working full time whilst being pregnant and looking after a toddler meant there was no way I could manage it myself. Allie went above and beyond to help bring my vision to life. The brief was “coastal luxe” and she absolutely nailed it. She sourced samples, trades and quotes. She brought her own design elements to the project, presenting gorgeous ideas I hadn’t even thought of whilst keeping with our overall look and feel. She took the stress out of selecting paint colours, sourcing floorboard samples, laundry tiles, kitchen cabinets, stone tops, lighting, carpet and more. She also helped us navigate ways to save money with clever design ideas. Allie paid for herself through the savings she got us. She was the best investment we made throughout the whole process. She’s also just a lovely person to work with. Can’t recommend enough.Read More

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
