They are the fab foursome whose multi award-winning show The Living Room has captured the hearts of Australia's everyman/woman on Friday nights with their often crazy antics and heartfelt makeovers.
Chatting with master builder Barry Du Bois is a lesson in architecture and its relationship to people.
"Architecture is all about how humans interact moving through a space," Du Bois says. "How people use certain rooms, and the cohesion between function and lifestyle."
And he should know, having studied Interior Design and Human Movement in the Build Environment at the University of Venice, Italy, no less.
He says in early building designs the kitchen had no real reference to outdoor space.
"In Australia we like to have the kitchen next to the outdoor space. We see the kitchen as a place of welcoming, to get from the public zone to the welcome zone - without going through intimate zones.
"We are such an adventurous people. The majority of Americans live in the middle of country and live in the middle of their homes.
"Australians live in an island with people all living on edge of the country and the same goes for our homes.
Du Bois says the history of a country can be seen through its architecture.
"Adelaide and Melbourne's architecture was controlled by the Navy - built for movement and interaction. You don't need a car in Melbourne and the sports ground is the heart of the city.
"Sydney's architecture was controlled by the Army. You have to have a car in Sydney, and the sporting grounds are hard to get to and away from, he says.
I bet you didn't know that little gem!
So, let's get down to why this group of veterinarian Dr Chris Brown, radio/television host Amanda Keller chef Miguel Maestre and Du Bois works.
"The show is like a recipe," Du Bois says.
"We are an incredibly diverse and talented group, we love a chat, and we love hanging out together. When we're together we're happy. When I see them, I smile, and so does my family,
"That comes up on screen. I'm a big believer in humanity and the power of it. People welcome us into their homes and see us as an extension of their own family.
"Miguel brings so much energy to the space, when you see someone with so much love for life, it's like therapy. "
He has two kids who are close to mine, they're like cousins. And Amanda's boys are the nicest humans.
Du Bois says the four are best friends and share in each other's lives.
"We have very different personalities but Amanda is the glue. Her and I try to keep the boys [Brown and Maestre] in line, she is one of my best friends."
When he was diagnosed with cancer in 2011, Du Bois says Maestre gave him so much strength during his treatment.
In 2017, Du Bois announced on the show his cancer had returned.
"It was incredible. I felt love from people I hadn't even met. Every day I get messages of support. You can let it get you down, or do can do what I did, announce it on air and say we're going to turn this into a positive."
Apart from his The Living Room commitment, he co-authored a best seller - Life Force - with Maestre; has nine-year-old twins; is on the board of directors for R U OK? and supports the Cancer Council; goes surfing, sailing, car racing and motorbike riding; and has a successful podcast Hammer it Home.
"We fit everything we can in as best we can. I like to think I manage my work-life balance pretty well.
"I'm also 60, so I get help when I need to. I have an amazing team [on the show]. We try to deliver a trick or two in every makeover. I am in charge of the design and if we see an opportunity when we can wow with inspiration, we do it so people can try it at home.
"The real job of a designer is to get the brief and understand the client's life."
