Projects
Projects That Respect the Home — and the People Living in It
Our portfolio reflects thoughtful planning, structural understanding, and a commitment to building homes that work better over time.
Projects Designed for How Families Live — Now and Over Time
A Second Storey Designed to Let the Family Stay
This project focused on adding a second storey to an existing family home, allowing the homeowners to gain space without leaving the neighbourhood they love.
Careful planning was required to integrate the new level with the existing structure, manage light and privacy, and ensure the home continued to function comfortably during construction.
The result
Extending the Living Space — Not Just the Floor Area
This rear extension was designed to improve how the home is lived in day to day.
By opening up the kitchen and living areas and strengthening the connection to the backyard, the home gained light, flow, and flexibility for family life and entertaining.
The extension blends naturally with the original home, creating a seamless transition rather than
A Rear Extension Built Around Light and Movement
This project focused on reworking the back of the home to create a more functional open-plan layout.
Structural changes were carefully planned to maximise natural light and create clear movement between indoor and outdoor spaces.
The outcome is a home that feels larger, calmer, and better suited to long-term living.
Reworking the Home as a Whole
Rather than updating individual rooms, this renovation looked at the home as a complete system.
Layouts, materials, and finishes were considered together to improve flow, consistency, and everyday usability.
The result is a home that feels cohesive and considered, rather than pieced together over time.
A Calm, Cohesive Update for Long-Term Living
This renovation focused on improving functionality while maintaining a calm, timeless feel.
By simplifying layouts and aligning materials across the home, the space became easier to live in and maintain.
Every decision was made with longevity in mind.
