Interior design services for offices, schools, medical consulting rooms, commercial spaces and homes across Melbourne

Personal service

Your project is unique. Kerwin Interiors is here for you – not the other way around. Our approach for each project is simple – we listen and respond to what you need.


“Our jobs are always completed on time with Sarah’s own personal touch.”
Joe Deidun | Fintona Girls’ School


The first step is to have a chat with Sarah about what is and isn’t working in your current space. Sarah loves getting to know her clients – it’s one of the things she loves about running a small business. We guarantee personal service every step of the way.


“Sarah consulted with us and listened to what we were trying to create for our new business.”
Will Hamilton | Hamilton Wealth Management


Flexible Solutions

If you have a clear idea of what you want, then Sarah can jump right in and get started. But don’t worry if you’re a bit unsure about where to begin. Sarah has worked in the interior design industry for over 20 years and can show you plenty of ideas for inspiration. See why Sarah’s clients love her stylish and practical fitout designs.


“Kerwin Interiors made everything so simple. We really appreciated the attention to detail and creative approach.  Our whole office has been upgraded.”
Peter C Neville | Peter C Neville & Associates


Do you like the sound of outsourcing the headache of managing your changes so you can focus on keeping your own business running? Sarah has decades of project management experience and will keep you informed every step of the way. Kerwin Interiors can project manage your fitout from start to end, or just one part of the process – you choose what works for you.

Industry knowledge

Kerwin Interiors clients benefit from Sarah’s network of industry contacts. Let Sarah know what’s important to you when choosing a product. Perhaps the source of material is important? Kerwin Interiors supports Australian businesses wherever possible. Sarah can make sure Australian made products are used for your project. Or perhaps reputation is important to you? Sarah has seen manufacturers come and go over the years. She knows which suppliers will be around to support their manufacturer warranty. And price is surely important? You will be impressed with the competitive prices and being able to choose from wholesale product ranges.


Sarah always listens to our needs, offers great advice and will source products from a variety of suppliers to find the one most suitable for our needs.”
Andrew Reynolds | Garry and Warren Smith Mazda


Need to choose a new paint colour for your fitout? No need to worry about 50 shades of grey! Sarah will give you large A4 Dulux paint samples (not those tiny squares) so you can be confident in choosing your new colour scheme. And you’ll be spoilt for choice with 50 commercial Laminex colours and a wide range of timber veneers to choose from.


Sarah’s knowledge & practical advice ensured the whole process from design to the furniture & finishes selection were an easy process.”
