A relaxing retreat worthy of its beautiful setting.


We worked collaboratively with the builders and client on this substantial renovation of this home. Stripping away and transforming this house into a relaxing retreat worthy of its beautiful setting and creating a home.

We were responsible for the kitchen and bathroom design, interior finishes throughout as well as the furnishings and furniture. 
This home needed to be versatile – for family & entertaining, both formal & casual – as well as a comfortable private sanctuary.

Sonya came onboard when our house renovation was already underway & fair to say was meet with a few existing challenges that she confidently & successfully turned around resulting in an end product far superior to what we could have hoped to achieve. 

Sonya is friendly, creative, professional & knowledgable not only about her profession, but the building industry as well. She listened, understood our needs, budget & style & was our deciding vote when as a couple we couldn’t agree. 

We couldn’t recommend Sonya more highly & look forward to working with her again in future projects.

Materiality & durability of the finish was important in grounding the kitchen design into the environment.


Very early in the design of this home Sonya Cotter spotted this stunning stone slab and knew that it was the focal point and drama the kitchen needed.  We showcased the stones natural flow by waterfalling it gracefully to the floor.

This kitchen is absolutely the heart of the home and filled with light and natural organic farm produce. On weekends when the property overflows with guests and family the traditional Smeg Victoria Range is in constant use. 

Cleverly disguised doors within the back wall cabinetry lead though to a well appointed scullery, laundry and mudroom. The bespoke steel frame that clads the stone add to materiality and durability. This after all is a hard working kitchen on a hard working farm.

A coastal lodge renovation for any season.


Now unrecognisable from the simple bach it once was, this old-girl underwent a major facelift indoors and out. The brief was to create a place the clients could enjoy year round. Functional spaces and practical finishes were also a high priority in this busy bach.

The result was a Coastal Lodge aesthetic.  Oiled oak flooring, schist features and the colour palette provide a connection to the environment.  Versatile seating options in the living space take advantage of the views offered up by windows. Lighting features and the indoor fireplace are cosy in cooler months. Soft whites, blues and greys and warm wood tones are calm and breezy.  This is the perfect place to unwind in any season.

Contemporary Interior With Timeless Appeal


This city-fringe villa was artfully updated to fit the owners’ busy lifestyle with children and a passion for entertaining.  Working closely with the client in designing the entertainers’ kitchen complete with hidden scullery and under-floor cellar ensured we met brief.

Creating a harmony in contrast was the aesthetic design goal for the project.  Crisp white walls provide the ideal backdrop for the layering textures of stone, marble, natural linens and oiled timbers.  Modern iconic furniture, fittings and bespoke built-in feature cabinetry sit comfortably amongst the villa's original features.  

"This home is enduring with timeless appeal."

An extensive yet seamless renovation on Sydney's North Shore


A generous hallway with art-covered walls sets the tone of the home and welcomes you through to an open plan kitchen living and dining space.

The project was a renovation or a small brick bungalow to a five bedroom family home with multiple living spaces located on Sydney's North Shore. 

The client wanted a soothing light palette of whites and greys warmed up with French oak floors throughout. There was no compromise on quality; the results are stunning. The success relies on the attention to detail.

Sonya Cotter Design is located in Auckland, and the project was in Sydney. That being said there were no issues with design communication across the team. This was primarily helped with the consistency of products and suppliers between New Zealand and Austraila, along with a number of Skype calls. 

Sonya Cotter Design worked closely with the client. The brief included the selection of finishes, the colour palette, the design of the kitchen, bathroom and sourcing furniture and lighting.

Sonya has been instrumental in the whole process of our build consulting from initial concept stage right through to implementation.
Sonya’s most valuable quality was understanding and embracing our aesthetic which she then translated into a cool, calm and tranquil space. Her eye for the finer detail and creative flair is exactly what we needed to bring the project together. Sonya oversaw everything from architectural design, colour selection, joinery, furniture and soft furnishing.

We have a beautiful family home thanks to Sonya.

Four levels re-built from the ground up. The result was a grand statement acknowledging the home's former glory. 


Five bedroom, five bathrooms, three living spaces, two kitchens including a scullery, plus one large well appointed laundry. This projects bespoke features certainly kept the team a Sonya Cotter Design busy with the detail. Great clients and diligent liaison with contractors and suppliers which even included sourcing the limestone direct from Italy was a large part of the projects success.

Working with a traditional colour palette was key.


When we first saw this property it was broken up into three flats complete with students sitting around watching the cricket. We saw past the chaos of tenants, the lean-to structures and unusual dividing walls to the properties potential to once again be a home.
We worked with an architect opening up spaces to accommodate a modern lifestyle while great care was taken to reinstate some of the original elements. We played with traditional colour and texture to give this old villa back her dignity.

Warm, Light & Welcoming.



When the kitchen is the centre of the home it has to be many things, especially when the busy family all enjoy cooking. 

The expressive character of the crown cut timber veneer added a high end decorative element to this highly functional kitchen. The design played with the symmetry of the room creating bold blocks and powerful negative spaces. The space is bathed in warm light during the day and in the evening hidden LED lighting creates the cozy atmosphere needed in this open plan environment. 

The main kitchen hides away the integrated side by side Fridge & Freezer.  The balance of the appliances feature a Wok Burner alongside the versatility of induction cooking. A Cool Draw, and Combi Microwave add to the functionality of the hard working scullery. An "out of the way" place to create regular snacks, coffees and work lunches. All easily cleared away with the help of a handy Dish Draw.

We meet the clients very early in the planning of their home. The kitchen was definitely the central element in developing the design concept and palette from which other spaces have flowed to create a cohesive and welcoming home.

This Kitchen Has Secrets



This stunning contemporary kitchen has a wall of dark stained oak veneer cabinetry cleverly housing a comprehensive scullery, fridge/freezer, pantry and a home office. 

The island top is made from slate with the addition of a cantilevered timber slab overlay increasing the social flow around the island and adding the element of cohesion between the bench and the flooring.



Whangamata Bach


The brief for this beachfront holiday home’s kitchen was to keep it a simple bach kitchen but with the sophistication and functionality of a home kitchen.  The key here was to maintain the access to the remarkable view which has been achieved by firstly housing the ovens side by side in a mid-level cabinet allowing a view port between this and the cabinet above and secondly installing a pop-up extractor fan in the bench, obviating the need for a drop down range hood which would have impeded the view.  The bench top is Corian and the cabinetry a natural stained oak veneer.  The splash backs are glass, chosen for their reflective quality and easy maintenance.



White on Track


The 4 metre Atlantic Granite bench is the focal point in this large family kitchen located in the leafy suburb of One Tree Hill.  The clean lines and white palette on cabinetry and walls ensure that this bench and the corresponding cooking area behind remain the main visual interest with the grey and green tones enhancing the connection between indoors and out. The hidden pantry and wall ovens combine to make this a functional and timeless kitchen

A State Of Mind


This compact and cost effective kitchen has been part of a significant renovation to a classic state house.  With the use of white glossy melamine and a rimu timber veneer detailingto match the exisiting polished floor, the clients collection of mid-century furniture and accessories feel right at home.


Danbri Farm


We’ve given this rural farmhouse kitchen a modern and refined look while maintaining its essential
role as the heart of this busy working farm.  An abundance of natural light coming from the french doors and skylights allowed the use of dark cabinetry and the choice of the stunning granite is used to great effect by waterfalling both ends.  The Smeg Victoria Range gives the kitchen its nod to
the past with its traditional styling, as do the Cotswold tiles on the splash-back adding texture.  The doors to the hard working service areas are seamlessly integrated into the cabinetry.



Contemporary Villa Kitchen


This busy family kitchen manages to be both extremely functional and super-stylish.  This has been achieved by keeping the finishes hard wearing and practical.  The cabinetry has a matt black lacquer finish, the bench is Corian with the addition of a cantilevered timber slab at table height, allowing the children to eat and do their crafts while still being a part of the action. This kitchen is an entertainers dream with the hidden scullery and an under-floor wine cellar……
