About

Sonya Cotter Design shapes New Zealand’s most refined residences. Recognised for interiors that embody enduring sophistication and layered materiality, the studio is known for harmonising architecture, lifestyle, and detail.

We take time to understand the rhythms of your life. How you move through spaces, how light shifts across your day, and what details bring you joy.

From these conversations, we craft interiors that are not only beautiful but deeply attuned to you. Proportion, flow, and materiality guide every decision. Bespoke joinery, curated artworks, and tactile surfaces add depth and meaning, creating homes that feel unmistakably yours.

“Design is not just about finishes. It is about presence, flow, and soul.”

Testimonials

We worked with Sonya progressively over 4 years on our interior design project. What impressed us most was the complete vision and the way everything tied together so well by completion. Her choice of materials, palette & style were so in tune and complemented the property. We are absolutely thrilled with the final result - no way could we have achieved it by ourselves. Highly, highly recommended

Peter Hardy

Sonya Cotter is an exceptional designer and a true professional. She helped us rebuild our home after a fire, and the result is even better than the original. Her calm, intuitive guidance through colours, fittings and layout made a daunting process feel effortless. We now have a home that radiates style, peace and personality. Highly recommend.

Deborah Eb

We have had the pleasure of working with Sonya on the interior design of our family home. Her thoughtful and innovative approach respected the brief but pushed the design to a level that exceeded our expectations.
