A thoughtfully crafted development located in the peaceful, tree-lined suburb of St Ives, Sydney. This elegant project comprises four premium dwellings, arranged as two semi-attached dual occupancies, each designed with a strong focus on liveability, privacy, and architectural clarity. The homes are unified by a timeless, modernist aesthetic, characterised by crisp white facades, strong horizontal lines, sculpted forms, and extensive glazing that invites natural light deep into each interior. Lush landscaping and carefully framed outlooks soften the built form, creating a sense of calm and connection to the leafy surroundings.
Each of the four dwellings spans three levels, including a basement level with secure parking and storage, and is fully connected via internal lifts, offering convenience and accessibility for occupants at every stage of life. The ground floors are designed as open-plan living zones with direct access to spacious private courtyards, perfect for outdoor entertaining or quiet relaxation. Upper levels house generously proportioned bedrooms and bathrooms, with carefully positioned windows and balconies that maximise light while maintaining privacy. The rear gardens further enhance the suburban charm, providing a green backdrop and ample space for family life.
With a strong emphasis on material quality, spatial efficiency, and environmental responsiveness, St Ives Duplexes reflect SN Architects' commitment to delivering contextually sensitive, high-end housing that meets the evolving needs of contemporary families. The project stands as a benchmark for luxurious multi-dwelling housing that doesn’t compromise on design integrity or lifestyle aspirations.
The residences showcase a harmonious blend of natural and modern materials. Warm timber battens and crisp white render create a visually appealing facade, while expansive windows bathe the interiors in natural light and offer stunning views of the surrounding landscape. Timber soffits add a touch of warmth and sophistication to the exterior, further enhancing the project's contemporary aesthetic.
Responding to the sloping terrain, SN Architects have incorporated a clever design element: planter boxes in front of the balconies. These not only add a touch of greenery and visual interest but also help to create a sense of privacy for residents. The inclusion of a plunge pool in the outdoor space provides a refreshing escape and further enhances the sense of luxury and relaxation.
This project exemplifies SN Architects' ability to seamlessly integrate design with the natural environment. By thoughtfully utilizing the sloping site and incorporating a range of sustainable features, they have created two stunning residences that offer both comfort and connection to the outdoors.


The Stanmore Duplex project has been designed to preserve and enhance the existing character of the streetscape. The massing emerges as a contemporary response to its context, using an abstraction of the adjoining Victorian terraces, it becomes a reinterpretation of key architectural elements within the urban grain. The reductive approach was applied to create a modern architectural statement within this established residential area.
Although the building is narrow, light and air circulation was not compromised. The interior spaces also took advantage of the longitudinal slope of the site via a stepped-down floor plate following the natural contours of the land, and in the process optimized foundation costs.
The Stanmore Duplex is a remarkably efficient space. The kitchen, dining room and living room all open onto one another and onto the backyard via a large sliding glazed door. The living spaces occupy the back portion of the ground floor, which is raised by a few steps from the garden, and offers a direct link to a large deck with a plunge pool. Although it's narrow, these units still manage to capture plenty of natural light, air circulation, and views of nature without compromising liveability.


The architectural language is defined by a sophisticated material palette. Crisp white rendered walls provide a timeless backdrop, beautifully juxtaposed with the contemporary lines of the aluminum battens. This interplay of textures creates a dynamic facade that captures the eye and lends a sense of modern elegance to the project. Large windows, strategically placed throughout both residences, not only flood the interiors with natural light but also frame picturesque views of the surrounding neighborhood.
SN Architects have cleverly utilized the corner block to ensure both privacy and a sense of openness for each dwelling. The orientation of each residence maximizes individual outlooks and access to natural light, creating a harmonious balance between the two structures. This dual occupancy project exemplifies SN Architects' commitment to innovative design, crafting functional and aesthetically pleasing spaces that cater to the diverse needs of modern living while enhancing the streetscape.
Located at the highly sought-after address of New Street, Bondi, NSW 2026, the New Street Residences represent a new benchmark for sophisticated, high-end residential design. As the demand for premium duplex projects in the Bondi area continues to grow, SN Architects has delivered a masterful architectural proposal that balances modern density with profound environmental sensitivity. This dual occupancy development not only addresses the practical needs of contemporary family living but also enriches the established streetscape, seamlessly integrating luxury architecture with the natural beauty of Sydney's Eastern Suburbs.
Navigating the Waverley Council Area with Considered Architecture
Designing and executing a successful dual occupancy within the Waverley Council area requires a deep understanding of local planning frameworks, site-specific soil conditions, and community expectations. Waverley Council places a strong emphasis on preserving the character of its neighborhoods, carefully monitoring floor space ratios, height limits, and boundary setbacks. SN Architects approached the New Street project with these guidelines at the forefront, crafting a proposal that navigates compliance while maximizing spatial luxury.
By stepping the built form back generously from the street boundary, the design respects the scale of neighboring traditional bungalows while proudly asserting its modern identity. This thoughtful setback minimizes visual bulk and overshadowing, preserving the amenity of adjacent properties. It serves as a prime example of how duplex projects in the Bondi area can be introduced gracefully, allowing increased density to coexist harmoniously alongside existing low-density homes.
Sculptural Forms and Textural Contrast
The architectural language of the New Street Residences is defined by a striking balance between grounded permanence and airy lightness. The ground floor of the duplex is clad in an elegant, dark vertical batten screening that anchors the building to its coastal site. This robust, tactile base provides essential privacy and security for the occupants while establishing a sophisticated street presence.
In striking contrast, the upper volumes of the dual occupancy transition into a smooth, light-toned finish, sculpted with sweeping curves that soften the building's geometry. These curved architectural elements offer a subtle nod to coastal modernism, effectively softening the facade and allowing the twin pavilions to sit lightly within their suburban context. Expansive floor-to-ceiling glazing punctuates the upper level, deliberately positioned to frame neighborhood views and flood the interiors with natural sunlight—a critical consideration for maximizing passive thermal performance and everyday comfort.
Biophilic Design and the Preservation of Natural Heritage
A defining triumph of this project by SN Architects is its uncompromising commitment to biophilic design and the preservation of the site’s existing natural assets. The front of the property is graced by a magnificent stand of mature, sculptural trees, which the architectural proposal carefully works around rather than against. The generous street setback was purposefully designed to protect these established root systems and canopies, allowing the ancient branches to remain the focal point of the streetscape.
To further blur the lines between the built environment and nature, the design incorporates a "living ribbon" of cascading greenery. Deep, integrated planter boxes wrap around the mid-level of the facade, allowing lush foliage to spill gracefully over the dark battens below. This strategic landscaping softens the modern lines of the dual occupancy, creates a natural privacy screen for the upper-level living spaces, and visually tethers the new residences to the natural environment.
Setting a New Standard for Bondi Duplex Developments
The New Street, Bondi proposal by SN Architects exemplifies the future of intelligent coastal development. By prioritizing organic forms, abundant natural light, and a profound respect for local ecology, this project transcends the standard expectations of a residential duplex. It stands as a testament to the fact that dual occupancy developments in the Waverley Council area can be deeply site-responsive, offering an elevated, sanctuary-like living experience while making a highly positive, sustainable contribution to the vibrant architectural fabric of Bondi.


The Castle Cove Duplex is a contemporary residential project by SN Architects, designed to offer the comfort, privacy and quality of two individual homes within a carefully considered duplex development. Located in the leafy Sydney suburb of Castle Cove, the project responds to its elevated site, natural surroundings and beautiful outlook with a refined architectural approach that balances lifestyle, functionality and visual appeal.
Unlike a conventional duplex where the two dwellings are attached along a full shared wall, the Castle Cove Duplex has been designed so the homes are only connected at the basement level. This unique configuration allows the upper levels to feel more independent, giving each residence a stronger sense of separation, privacy and identity. The result is a dual occupancy development that does not feel like a standard attached dwelling, but rather two elegant homes that work together as part of one cohesive architectural composition.
The project is arranged over three storeys, taking advantage of the site levels and the available views. The elevated position allows the main living areas, bedrooms and outdoor spaces to connect with the surrounding landscape, creating a sense of openness and calm throughout the homes. Large windows, carefully positioned balconies and generous internal spaces help frame the outlook while allowing natural light to reach deep into the interiors. Every part of the design has been considered to improve daily living, enhance comfort and maximise the value of the site.
Architecturally, the Castle Cove Duplex combines contemporary design with soft curved forms, warm materials and a refined external finish. The curved roof edges, rounded wall elements and vertical columns create a sculptural appearance, softening the overall building form and giving the project a distinctive identity. The use of natural stone, light rendered surfaces, warm timber-look soffits and dark-framed glazing creates a balanced material palette that feels modern, timeless and suitable for the Castle Cove context.
A key focus of the design was to provide each dwelling with privacy while still maintaining openness, natural light and strong connections to outdoor areas. The layout has been carefully planned to reduce overlooking between the two homes and neighbouring properties, while still capturing views and creating generous living spaces. Landscaped areas, balconies and outdoor zones are integrated into the overall design, helping the homes feel connected to the site and surrounding greenery.
The Castle Cove Duplex demonstrates how thoughtful duplex design can provide much more than a simple side-by-side development. By attaching the dwellings only at the basement level, SN Architects has created a project that improves privacy, enhances architectural quality and gives each home a greater sense of independence. The three-storey design allows the homes to respond to the natural slope of the land while making the most of the outlook and available space.
This project reflects SN Architects’ approach to residential architecture in Sydney: designing homes that are practical, elegant and responsive to their site. The Castle Cove Duplex is a strong example of how a contemporary dual occupancy can achieve a high level of amenity, architectural character and lifestyle value while respecting its surrounding context. With its unique basement connection, sculptural form and beautiful views, the project offers a refined model for modern duplex living in Castle Cove.
One of the standout features of this residence is its careful consideration of the natural surroundings. The site's gentle slope towards the rear provided us with the perfect canvas to craft a home that effortlessly adapts to the land.

The façade showcases a clean, modern composition of crisp lines, soft curves, and warm timber textures, balanced with large expanses of glass to create light-filled interiors. Each residence is distinct yet designed in harmony, achieving a sense of individuality while maintaining a cohesive architectural identity.

The design is defined by two balanced architectural volumes that clearly express the duplex typology while maintaining the individuality of each dwelling. Clean geometric forms and strong horizontal roof planes establish a contemporary architectural language, while the symmetrical composition provides a calm and ordered street presence. The entry is positioned centrally between the two homes, creating a clear and welcoming arrival sequence that enhances both functionality and visual balance.
A key feature of the façade is the combination of soft curves and vertical textures at the lower level. Gently curved walls with vertical cladding elements introduce depth and elegance to the street frontage while helping to soften the building’s mass.
