What we do
We work across new builds, renovations and heritage restoration — treating each as a single design problem rather than a stack of trades.
01 — Architectural Design
What it is
Custom residential architecture for premium Brisbane sites. Concept, documentation, council approval, contract administration through to handover.
Where it suits
Riverfront and acreage sites where the architecture is the brief. Considered, restrained homes that age well.
02 — Renovations & Extensions
What it is
Major renovations and extensions to existing homes. We resolve plan, light and circulation in equal measure — not just adding rooms.
Where it suits
Mid-century homes, contemporary builds in need of repositioning, and family homes outgrowing their original footprint.
03 — Heritage Restoration
What it is
Restoration and sensitive extension of heritage and character homes. Council-savvy, contractor-aware, considerate of original detail.
Where it suits
Pre-1946 Queenslanders, Federation homes, post-war character homes in Brisbane's heritage precincts.
Interior architecture, landscape collaboration and bespoke joinery also offered — enquire for project-specific scope.
What we believe
Architecture, done well, is the accumulation of disciplined decisions. Three of them sit at the foundation of every Halden & Co project.
Orientation, breeze paths, sun angles, the position of the neighbour’s gable, the slope of the land — the site has already started the design before we open a sketchbook. Our job is to listen to it before deciding what the home wants to be.
A beautiful elevation built on a confused plan is just expensive failure. We resolve how the family will live in the home — daily paths, light, gathering, retreat — before we settle the form. The exterior follows from the interior, never the other way round.
Specifying materials that look beautiful day one is the easy part. We specify materials that age — that take Brisbane’s sun, humidity and tropical rain and become more themselves over twenty years, not less. The home should look better in 2045 than it did in 2025.
How we work
Architecture is a long conversation. We move at the pace the project deserves — never faster, occasionally slower, always considered.
You reach out by email or phone. We have an unhurried half-hour conversation about the site, the brief, the family, and whether we’re the right practice for the project.
We visit the site together. We listen more than we talk. The brief takes shape over two or three sessions before any line goes on paper.
Six to eight weeks later, we present concept directions, model-built and tested against the brief. We narrow with you and refine.
Design development, full documentation, council approval, builder selection, and contract administration through to handover — we stay with the project from first sketch to first dinner in the home.
About the studio
Halden & Co is a Brisbane architecture practice working on premium residential projects across the city’s established suburbs. We take on six to eight projects a year — small enough that the directors are personally on every site, large enough that the practice has the depth to handle complex documentation, council overlays, and contractor coordination.
Our work is restrained, climate-aware and detail-led. We don’t chase trends or scale. We pick projects where the architecture is the brief and the client values getting it right over getting it fast.
The practice is registered with the Australian Institute of Architects and holds professional indemnity cover appropriate to project scale. References available on request.

What clients say
Selected reflections from clients across Brisbane’s residential pockets. References to specific projects available on request.
“Halden & Co restored our 1920s Queenslander with extraordinary care for the original detail. The new rear extension reads as a continuation of the home, not an addition to it. Twelve months on and the work feels inevitable.”
“We approached three practices. Halden & Co were the only ones who came to the site, listened, and asked the right questions before drawing anything. The result speaks for itself — on brief, on budget, on time.”
“The first concept they showed us was so close to what we’d been trying to articulate for years that we knew immediately. They listened, they tested, they refined. Our home is the better for it.”
“An acreage build with significant complexity — council overlays, structural challenges, and a builder we already had relationships with. Halden & Co coordinated all of it without a single stumble.”
“Heritage overlay, character precinct, two-storey extension. Most architects told us it couldn’t be done. Halden & Co spent three sessions with council before we lodged. The DA was approved without conditions.”
“Second project with the practice. Same quality, same considered approach, same deliberate pace. The kind of architects who turn into long-term advisors, not just consultants on a single build.”

We respond to enquiries within two business days. The first conversation is unhurried — we want to understand the project before we talk fee or timeline.
