01 — Our approach
A little less noise.
A little more belonging.
Home is the quiet foundation
from which life unfolds.
A room can look beautiful and still not feel right. We believe good design begins with understanding how you live, what matters to you, and what a space could become.
Natural light. Thoughtful materials. Room to breathe. Interiors that feel personal, considered, and easy to live in.
A sense of Heim
A visual moodboard of light, texture and warmth.

04 — A few things to know
A clearer place
to begin.
Thinking about your space?
Here are some useful starting points.
What does Heim Design do?
Heim Design offers interior design, spatial planning and design consultation. Led by Kelly Mangin, the studio works with residential and commercial spaces in New Zealand.
Explore the servicesHow is spatial planning different from interior design?
Spatial planning focuses on how a space is arranged: the layout, flow, light and relationship between rooms. Interior design brings together the wider look and feel, including materials, finishes and styling. The two often work together.
Can I begin with a design consultation?
Design consultation is one of Heim Design’s services. It offers focused guidance around your space, brief or a particular decision. Email Kelly with what you have in mind to discuss a suitable starting point.
Where is Heim Design based?
Heim Design is based in New Zealand. Include your project location when you get in touch so Kelly can discuss how she can help.
What should I include in my first enquiry?
A few words about your space, where it is, and what you’d like to change are a good start. If you have a timeframe, budget, photos or floor plans, you’re welcome to include those too. You don’t need a finished brief to start a conversation.
How do I find out about fees and availability?
Contact Kelly directly to discuss fees and current availability for your project. Share whether you’re looking for interior design, spatial planning or a consultation, along with any timing you have in mind.
