Adelaide Interior Architects & Interior Designers

From blueprint to final cushion — and everything in between.

We don't just make rooms look beautiful. We reimagine how you live in them — from structural space planning right through to the finishes, the furnishings, and those final "oh yes" moments.

Beige is what happens when nobody makes a decision. We make decisions — the structural ones that determine how your home breathes, flows and functions, and the aesthetic ones that make it feel like nobody else's house on the street. Because most Adelaide homeowners renovate once. One chance to get the layout right. One chance to choose materials that won't date in three years. One chance to make a home that actually fits the way you live.

As Adelaide's interior architects and interior designers, we make that one chance count.

What Makes Us Different?

Design and build. One team. No translation errors.

Most designers hand you a gorgeous concept and wish you luck with a builder. That gap is where budgets blow out and visions get quietly watered down.

Through our partnership with Morcon — our build and engineering team — we stay with the project from first sketch to final styling. One vision, executed by people who were in the room when it was decided.

How It Works

From First Sketch to Final Reveal

The Design Foundation

Before a single wall moves, we establish the complete creative vision — spatial layout, architectural intent, and a plan that makes your home work as beautifully as it looks.

The Renovation Blueprint

Concept approved, now we get precise. Detailed buildable drawings, every finish and fixture selected, documentation that leaves nothing to chance on site.

On-Site Management

This is where most designers disappear. We don't. Expert oversight alongside Morcon, from first swing of the hammer to final styling.

Design Power Session

The best place to start? Right here.

Two focused hours on your plans, your pain points, and the questions keeping you up at night. You'll leave with clarity, direction and advice that's specific to your home — not general principles you could have found on Pinterest.

It's not a sales pitch. It's a working meeting.

Two hours — $528 incl. GST In person across Adelaide and the Hills, or on Zoom anywhere.

No obligation to go further. If a full project makes sense afterwards, we'll prepare a proposal then.

  • “Your designs took my breath away in the best possible way. They are beautiful and better than I imagined; elegant and bold yet warm and inviting. I’m a very happy girl"

    Teresa G. Toorak Gardens

  • “Working with Penelope is like working alongside a close and trusted friend. She listens, is generous with her time and non-judgemental”

    Sheryl W. Aldgate

  • “The reno is absolutely gorgeous. I had reservations about the scale of what we were undertaking, yet it all looks amazing. For me, to have a kitchen that is functional AND beautiful was certainly the brief, but it is also beyond what I could have anticipated. Living in it now, it’s just beautiful and functional and so amazing”

    Michelle P. Highbury

  • “Penelope was able to take all our ideas and develop a design that would work well for our family of five. With Penelope's help we decided to complete the renovation and it has totally transformed our home and the way we live. Penelope gave us the confidence to compete the large renovation we’d be talking about for 8 years”

    Sophie C. Crafers

  • “We had a wonderful experience with Plush Design Interiors, and would recommend Penelope to anyone looking for beautiful, practical interior design ideas and advice. Working with her gave us the courage to make choices that resulted in beautiful, stylish rooms that we would never have achieved on our own”

    Rachel E. Toorak Gardens

  • “It was such a relief to hand my bedroom project over to Penelope. Her ideas were brilliant and together we made selections. I never felt pressured to make a decision, instead everything revealed itself. I feel that every time I walk into my bedroom I’m walking into a six star resort”

    Jan R. North Adelaide

  • “By the time we engaged Plush Design Interiors, we had started renovating. It was all a huge mess. Plush Design Interiors reignited the passion with a clear and creative approach to fixing the problems we had created. To have our renovation back on track with a clear vision was such a relief”

    Terry S. Aldgate

  • “Our new space is a great blend of sophistication and fun with a mid-century modern and 60’s retro feel. My three kids were included in some of the discussions around their own spaces, which they really appreciated”

    Mark H. Parkside

  • “Penelope is a delight to work with and has a warm personality which she uses to great effect to guide and support choices, never imposing her own view but gradually guiding one towards the best scheme for the space. It was a great experience”

    Sue D. Kensington Gardens

  • “Fantastic professional, very personable and truly takes her time to take your own personality, furniture and environment into consideration when putting forward ideas”
