’’One thing we loved about working with Ciaran was the 3D walk- through modelling technology.

Having a 3D model of the house was so valuable through the design process. We were able to get a real feel for the flow of the house and picked up on some important changes before a shovel hit the ground, saving us money and making our home better.

We also downloaded the software onto our iPad to show our friends and family the 3D model, which was so fun.”

Sustainable building design services FAQ

I don’t live in WA; can you help me?

Yes. I’d be happy to discuss your project.

While most of my clients are based in southwest WA, I‘ve designed homes for clients in the northwest and a small holiday resort in Indonesia.

Will you work with my builder?

Certainly, I work with many of the southwest’s most renowned builders. I also partner with a handful of talented newcomers. If your builder belongs in either group or they don’t, I’d be happy to collaborate with them.

Can you help me get building approval?

Absolutely yes. I can project manage as many aspects of your build as you’d like. This includes piloting your project through all its required approvals.

What are your fees?

Zero until we’ve had a comprehensive design consult about your project.
Based on our discussions, I’ll provide a formal project proposal that includes my fee. It will be detailed, complete and it’ll respect your budget.

Once you agree to proceed and make a 20% initial project payment, your project secures its place in my workflow.

Can you rework my old drawings?

I would love to have a look at them. However, I’d need written approval to work on drawings by your original building designer or architect as they own the copyright.
