Adelaide Interior Architects & Interior Designers

From blueprint to final cushion — and everything in between.

At Plush Design Interiors, we don't just make rooms look beautiful. We reimagine how you live in them. As interior architects and interior designers, we work at both ends of the spectrum — from structural space planning and architectural detailing, right through to the finishes, furnishings, and those final "oh yes" moments.

What sets us apart? We don't hand you a gorgeous design and wish you luck with a builder. Through our partnership with Morcon — our professional build and engineering team — we deliver a genuinely end-to-end experience. One vision. One team. No translation errors between design and construction.

Your home should be a true reflection of you, not a mood board ripped from last season's trends. Our job is to bring your vision to life with the architectural rigour, creative confidence, and professional backbone to actually build it.

From First Sketch to Final Reveal — We're With You the Whole Way

  • Clients and an interior designer from Plush Design Interiors  discussing renovation plans in a partially demolished kitchen with exposed brick wall.

    The Design Foundation

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

    The Renovation Blueprint

    Concept approved. Now we get precise. We develop detailed, buildable drawings, make every finish and fixture selection, and hand over documentation that leaves nothing to chance on site. No surprises. No "that's not what I meant."

  • Four people standing inside a house under construction, reviewing papers or documents together.

    On-Site Management & Completion

    This is where most designers disappear — we don't. Working alongside our build and engineering partners at Morcon, we provide expert oversight from first swing of the hammer to final styling. Your vision, executed exactly.

Design Power Session

The Best Place to Start? Right Here.

Before we scope a proposal, before you commit to a thing — a Design Power Session is where we get to work. In two focused hours, we'll dig into your plans, your pain points, your ideas, and the questions keeping you up at night. You'll leave with clarity, direction, and expert advice that's actually specific to your home.

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

Two-Hour Design Power Session — $480 + GST

After your session, if it makes sense to move forward, we'll prepare a detailed proposal outlining services, phases, and fees. No obligation, ever.

  • “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”
