Where proportion does the talking and every room earns its quiet

“We are not decorating rooms. We are arranging daylight, distance and material until a house finally behaves like yours.”

Our story

Halden started in 2019 out of one stubborn belief: good interiors begin with listening. We spend the first weeks understanding how you live before a single line gets drawn.

Every project is personal — built on real conversations, honest materials and a commitment to rooms that age well rather than photograph well.

“You gave us back forty square metres we already owned.”

The attention to every joint, from the oak millwork to the way the hallway now catches morning light, went well past what we asked for.

[ How we work ]

A clear path from
plan to handover

Every project follows the same three-phase rhythm, so you always know what is happening and what comes next.

Week 1—3 /01

Listening & survey

We start with how you actually use the place — habits, light, storage, the things that annoy you — then measure everything on site.

✓Site survey✓Budget frame✓Brief signed
Kitchen worktop and cabinetry, CC0 via Openverse
Week 4—8 /02

Drawing & material

Plans, elevations and a physical material box. We revise together until the room in the drawings is the room you pictured.

✓Layout set✓Material box✓3D views

Week 9—14 /03

Build & install

We coordinate trades, walk the site weekly, and place every piece ourselves on install day so nothing lands in the wrong corner.

[ Project process ]
How long does a typical project take?

Timelines follow scope. A single-room redesign usually runs 6–9 weeks, while a full-home renovation lands between 4 and 7 months from first sketch to handover.

What does your design process look like?
Do you take projects outside Oregon?
[ Investment & pricing ]
What does a typical project cost?

Every brief is different, so we quote after the first consultation. As a guide, single-room designs start around $7,400 and whole-home projects from $28,500 depending on scope and finishes.

Is the first consultation charged?
What is included in the design fee?
[ Design approach ]
Which styles do you work in?

Our portfolio runs from warm minimal to layered and collected. Rather than forcing a house style, we adapt to your taste while holding the line on proportion, light and material honesty.

Can you work with furniture we already own?
Do you produce 3D renderings?
