Who we are
Based in Auckland and Matakana, Sonya Cotter Design is a boutique interior design studio specialising in high-end residential projects and bespoke interiors. With more than 20 years of experience, we create refined, timeless homes that balance elegance, comfort, and individuality, designed for clients seeking enduring quality across their residences.
Every project begins with curiosity and understanding. Guided by expertise and intuition, we shape interiors that reflect the subtleties of your lifestyle. Through a considered interplay of space, light, and materiality, we craft environments that are sophisticated, deeply personal, and designed to stand the test of time.
Sonya Cotter Design approaches each commission holistically, blending artistry with technical precision. From architectural collaboration and spatial planning to custom joinery, furniture, and art curation, we ensure every element contributes to a cohesive vision.
Our work is defined by elegance and restraint. Whether a city residence, coastal retreat, or holiday home, each project is guided by meticulous attention to detail and a philosophy of creating interiors that foster connection, inspire calm, and embody luxury living.

MAUI
Summer 2024
Featured Projects
Water’s Edge Home - Maui
This full-scale renovation exemplifies modern, relaxed luxury.
Sonya Cotter Design collaborated with an international team of contractors and local New Zealand suppliers to reimagine this 18-year-old architectural masterpiece by Bossley Architects.
Collaborating with the Bossley Architects the kitchen was redesigned to enhance relaxed flow and update the visual appeal, while the master bathroom was transformed with a new layout, and a completely new guest wing was added.
Our team redefined the home's interior with a complete refresh of furniture and décor, along with expertly crafted kitchen and bathroom cabinetry, thoughtfully selected surfaces, and refined finishes. These elements come together to create a cohesive and modern aesthetic. Bespoke touches, combined with the clients' curated art collection, elevate every space and celebrate the home's unique character.
Experience the harmonious balance of function and beauty, tailored to the spirit of Maui living. Guided by a commitment to craftsmanship and elegance, our team took care of every detail, from the initial concept to the final flourish.

CLIFFTOPS
Summer 2021
Featured Projects
We are honoured to be awarded Interior Home of the Year for Clifftops.
Nestled on the clifftops between two volcanic landmarks, Lake Pupuke and the majestic Rangitoto Island, the surrounding organic forms influenced the home's interiors.
Our client has a significant art collection and the home's architecture is a sculpture in its own right. We successfully created intimate spaces despite the almost overwhelming sense of scale. We filled the vast areas with textures in both surfaces and in form, customising unique finishes and adding warmth and a sense of welcoming.
We had a wonderful client who trusted us to create a home for his family with a design that was unique and would endure.
We worked closely with Bossley Architects and associated craftsmen and contractors to ensure this successful outcome.
