We’d love to hear from you.
Design + build.
We offer a complete design + build service, guiding you through every stage of your home’s journey, from concept to construction. We begin by meeting with you on site to understand your vision, assess the existing conditions, and discuss how we can work together to bring your project to life. Our team will answer any questions you have, simplify the process, and provide you with the next steps.
Once we have a clear understanding of your needs, we will appoint you one of design collaborators, either architect, building designer and interior designer, that best suit your requirements. From that you’ll receive detailed sketches of your site plan, floor plans, elevations, and provided materials. We then provide an estimate based on our extensive experience, so you can see how your project aligns with your budget. After accepting our estimate, we’ll establish a tentative start date and move into the final documentation phase, including liaising with town planning, structural engineers, and building surveyors to prepare the necessary permits.
Throughout the process, we prioritise transparency, open communication, and complete honesty about costs and timelines. We understand that your home is a significant investment, which is why we focus on providing clear, detailed estimates rather than lump sums, ensuring you always know how your budget is aligning.
At Demardi, our expertise and passion drive us to create spaces that not only beautiful but also enhance your lifestyle. Our collaborative approach with clients, designers, and skilled tradespeople ensures that every home we build is a true reflection of your vision. From the first discussion to the final touches, we’re here to make your building experience enjoyable, exciting, and stress free, creating a home that you’ll cherish for years to come.

Park Orchards 11-12 (in progress)
We are thrilled to collaborate and oversee the complete design process and construction of our Park Orchards 11-12 house, managing every detail from start to finish. Working closely with both our building designer and interior designers, we carefully crafted a space that blends style and functionality. The design process was a true collaboration, with each decision, whether structural or aesthetic, tailored to enhance the home’s flow, comfort and connection to its beautiful landscaped surroundings.
From the initial concept sketches to the final construction, we ensured that every element came together seamlessly, creating a home that is both a reflection of our clients vision and a testament to thoughtful, intentional design.
Construct.
We understand that your home is one of the biggest investments you’ll make. That’s why, when you provide us with your plans, we take the time to thoroughly review all the details, ensuring every key element is captured. We dive deep into the scope, budget, and timeline of your project, allowing us to create a precise and detailed estimate right from the beginning. We believe in fully transparency, showing you exactly where your investment is going, so you can have complete confidence in every space of the build.
We know that having certainty about your project’s costs and timelines is essential, which is where we are committed to honesty and clear communication throughout the process. While there are always limitations regarding budget, space, and time, we’ll address any challenges upfront, ensuring there are no surprises.
Our goal is to make your building experience as smooth, exciting, and stress free as possible. By involving us early on in the process, we can work closely with you and your architectural design team to bring your vision to life and create a home you’ll love for years to come.

Preston 74
For our Preston 74 house, we embarked on an architectural knockdown and extension project that combined the best of the old and new. With a clear vision in mind, we worked closely with our clients to redesign and extend the original structure, ensuring the new space seamlessly integrated with the existing home.
The process was all about enhancing the functionality while maintaining the charm and character of the original design features. From the demolition of the old to the careful planning of each renovated / extended element, every detail was considered to create a modern, open home that perfectly suited the clients lifestyle.
