Adaptability and value

Our team will then guide you through every step of planning and development, from the initial concept to the moment you unlock the door to your new home. Some of the things we can assist you with include assistance throughout the planning approval process, coordination of external consultants, managing the tendering process and project management of your new home build. No matter how big or small your project may be, we will adapt our services according to your budget and requirements.


At dion seminara architecture, we start your design journey by exploring your wish list of non-negotiable and other must-have inclusions. This includes not just the specific features that you want but also any design aspects that reflect your dream, vision and values. By knowing exactly what you want and why you want them, we can create a home that will match your family’s needs and lifestyle through the years.


Starting a project with realistic expectations will ensure that the end result meets your expectations. When considering the development of your project, one of your main considerations should always be budget allocation. If you are serious about building custom new homes that will suit your style and stand the test of time, then you’ll need to start with a building budget of no less than $600k. We believe this figure is the ideal starting budget for getting custom new homes that are truly worth your time and money.
