Our Philosophy

Home is not a backdrop. It is the quiet foundation from which life unfolds.

What
we do

We work at the intersection of space, material, and feeling — creating interiors that are as considered as they are liveable.

01

Interior Design

Full-service design for residential and commercial spaces. From concept through to final styling, we bring coherence, warmth, and intention to every room.

02

Spatial Planning

Space should serve how you live. We create floor plans and layouts that prioritise flow, natural light, and the quiet efficiency of a well-considered home.

03

Design Consultation

For those who want expert guidance at key moments. A focused session to unlock the potential of your space, your brief, your vision.

We design spaces that feel curated rather than decorated, calm rather than empty, and entirely, unmistakably yours. — Heim Design

The Principal

Kelly Mangin

Founder & Principal Designer

Kelly brings a quiet precision to the practice of interior design — a belief that the best spaces are built on deep listening, thoughtful material choices, and an understanding of how people actually live.

Based in New Zealand, Heim Design takes its name from the Old Norse word for home — a place of belonging, shelter, and return. That sense of arrival shapes every project we take on.
