Customised Services and Advice

Sometimes it’s hard to know what you want until you see it, we get that.

During our pre-design services, we set out to identify what you’d like to change about your home. We learn what your preferences are to understand how you’ll truly enjoy comfortable living. We are then able to consult on a range of ideas from existing house designs, renovation plans to bespoke solutions.

We will do what we can to give you good advice and recommendations, no matter your needs. You will explore a diverse set of design options that meet your requirements, so you can choose which one works best for you. We will get our cost planner or a chosen builder to supply a professional costing at our concept stage.

We’re also 100% independent of builders and contractors. Our competitive tender process ensures we get the best fit of contractors to work on your project, for the best price.

Our Principal Architect, Dion Seminara, has over six years of university education. He also has over 30 years of ongoing professional development.

He is able to translate your thoughts as the homeowner into inspiring designs; designs that are suitable to the climate and surrounds.

Sustainable Architecture: We approach all of our projects with sustainability in mind. In this sustainable building approach any harmful environmental impacts are mitigated by:

Prioritising efficiency
Effective use of natural light and shade
Effective ventilation, layout and use of renewable materials
Using efficient insulation which can reduce the need for energy consuming temperature control, especially in the harsh Queensland climate.

End to End Inclusions: Our architectural process is likely the most holistic approach possible. Because of our expertise, from interior design to landscape design, we are able to match your needs to well-engineered ideas. This even includes placement and positioning of entertaining additions such as:
Pools and spas
BBQ areas
Tennis courts
Plus, efficient use of leisure and relaxation spaces like outdoor lounges
And creating theatre rooms and dens that consider privacy and sound-proofing

Architecture for Accessibility: Our designs keep accessibility needs in mind. If you have movement restrictions, we can design from the ground up at the beginning to ensure you can move around easily and safely. We measure access to all rooms and surfaces to ensure you will be able to move in and out of these areas easily, with as little compromise as possible.
