McMillan Interiors is:

Catherine and Ruth-Anne McMillan have worked in the Interior Design World collectively for over 30 years.

Together we offer considerable personal experience and bring a new dimension to the definition and enjoyment of “Home”

Our commitment is to be professional and responsible in all we do as we partner with clients to make their vision of home a reality

A Bespoke service:

We don’t do comparisons or imitations.  Each project is treated individually because you are unique – not a copy or an imitation.

Our goal is to draw from your own personality and creativity, helping you design a home interior that beautifully reflects your taste and style – providing a space which is beautiful, practical where needed, and a reflection of you, where you can rest and be comfortable.
