Koto Designs is a Perth-based interior design studio creating calm, well-resolved interiors through thoughtful spatial planning, material selection, and design strategy.

I work with homeowners and small businesses across Perth to design interiors that function well, age gracefully, and support everyday life.


Koto Designs provides interior design services for residential renovations, new builds, and small business and commercial spaces across Perth.

Services include interior design, spatial planning, and material and finish selection for residential renovations, new builds, and small commercial spaces including cafés and studios. Each project begins with a clear understanding of how the space needs to function before design decisions are made.


Every decision made is shaped by a clear sense of purpose.

Koto Designs approaches interiors as lived environments first and visual compositions second. Each project considers how people move through a space, how rooms connect to one another, how materials wear and age over time, and how light changes throughout the day. Storage, acoustics, and layout are treated as integral parts of the design, shaping interiors that feel calm, resolved, and comfortable to live in.

Meet the Designer

Hi, I'm Emma

An interior designer and artist focused on creating calm, thoughtful interiors shaped by how people live and use their spaces.

What my clients say:

“This has been such an amazing experience.

I think it can be quite overwhelming to think of all the possibilities and options at hand and weigh them against need, cost, compatibility etc. You have been incredible and managed to offset all of the above and whats more, turn this whole experience into something exciting to be treasured. Beautiful designs that we will keep with us forever.

Thank you thank you thank you!”

Planning a renovation or project in Perth? Let’s talk about your space.

Every project begins with a consultation to understand the space, the brief, and how the interior needs to function. From there, the design process develops through spatial planning, concept development, materials and finishes, lighting design, and documentation or visualisation where needed. Services range from focused design consultations through to full interior design support for residential renovations, new builds, and small commercial spaces.
