Our process

We offer a tailored start-to-finish design experience, from initial concept through to building approval.   As each project is unique, so are our solutions; you may opt for a complete project management solution, or for a simplified, more budget friendly approach.

+ FEASIBILITY STUDY

A feasibility study is a quick and low cost option to explore the design potential for your site.  This is possible before you even make a purchase.

+ NEW HOMES, TOWNHOUSES, DUAL OCCUPANCY

+ RENOVATION & EXTENSION

+ ENERGY EFFICIENCY CONSULTATIONS

Generally, fixed fees are agreed prior to commencement of design and vary based upon project scope, size and complexity.  

Initial consultation 

Make a time with us to discuss your vision.  Share your budget, timeline and any specific requirements and then we can ensure the project is viable and formulate a strategy to best assist you.  

Throughout the process, we’ll guide you step-by-step, ensuring that each phase is carefully planned and executed.  Our typical involvement includes the following stages, however you may only want to engage us for specific parts of the process.  

 

+ SCHEMATIC DESIGN

Develop initial design concepts and layout options.

+ DESIGN DEVELOPMENT & APPROVALS

Refine the approved design and begin making more detailed decisions.  In some cases planning approval will also be required.

+ CONSTRUCTION DOCUMENTATION & CONTRACTOR SELECTION

Technical drawings and specifications that detail how the project will be built.  

+ BUILDING PERMIT & CONSTRUCTION SUPPORT

Authority approval to commence construction and responding to contractor queries.  

3D Design:  All our projects are developed and viewable in 3D so that you can confidently envision your project from every angle, we can even provide you with a walkthrough to view in your own time.

Healthy, low VOC materials:  We prioritise materials that do not off gas and pollute your home.

Additional services

+ INTERIOR DESIGN

While our documentation includes core joinery and lighting layouts, we can extend this to a full interior design service, including material selections, finishes, fixtures, and curated mood boards. We also guide you in selecting healthy, low-toxicity materials to help reduce chemical exposure and support better indoor air quality.

+ ENERGY EFFICIENCY UPGRADES & LOW TOXICITY

Every home can benefit from forward planning, helping to reduce energy costs, humidity, mold and condensation and improve thermal comfort and well being.

+ PASSIVE HOUSE DESIGN & CERTIFICATION - For clients seeking a truly high-performance home, we offer Passive House design and certification services.

 

This globally recognised standard delivers exceptional comfort, consistent internal temperatures, and outstanding air quality, while dramatically reducing energy use.  In Queensland’s warm, humid climate, managing heat and moisture is critical to creating a comfortable, healthy and durable home. Through careful design of insulation, glazing, shading, and ventilation systems, we create homes that feel calm, quiet, and effortless to live in.  We can guide you through the process and tailor the level of performance to suit your project, whether pursuing full certification or integrating key Passive House principles.
