Home/What We Do

What we do.

Two disciplines, one practice — architecture and engineering resolved together from the very first sketch.

Architecture

Residential Architecture

From concept to consent, we design homes that are as structurally resolved as they are beautifully considered — whether you're building new, extending, or transforming an existing home across New Zealand or Australia.

Why choose us

Our architects work alongside our structural engineers from day one — meaning your design is never compromised by structural afterthoughts. One team, one conversation, one resolved outcome.

What we offer

Custom home design & documentation

Full architectural drawings from concept through to building consent.

New builds, alterations & additions

Architectural services for brand new homes and existing property extensions.

Multi-unit & townhouse developments

Design and documentation for medium-density residential projects under NZS/NCC.

Interior spatial planning

Room layout, flow optimisation, and spatial design for new and existing homes.

Heritage & character home renovations

Sensitive design solutions that respect and enhance heritage character values.

Resource & building consent support

Full council submission management and RFI responses across NZ and AU councils.

Architecture

Commercial Architecture

We design commercial spaces that perform — functionally, commercially, and architecturally. From retail fit-outs to civic buildings, our team delivers thoughtful, code-compliant architecture across NZ and Australia.

Why choose us

Commercial projects demand precision across multiple disciplines. Our integrated architecture and engineering team ensures your building performs structurally, operationally, and commercially from day one.

What we offer

Retail, hospitality & mixed-use design

Purpose-designed commercial spaces that balance brand identity with buildability.

Office fit-outs & workplace environments

Productive, compliant workplace designs from concept through to construction documentation.

Educational & civic buildings

Schools, community centres, and public facilities designed for longevity and compliance.

Healthcare & aged care facilities

Specialist design for regulated healthcare environments with strict compliance requirements.

Facade design & exterior detailing

High-performance facades designed for thermal efficiency, weathertightness, and appearance.

Concept to construction documentation

Full service from initial sketch through to IFC drawing packages for tender and build.

Architectural structure

Structures

Architectural Structures

We engineer structures that are meant to be seen — exposed steel frames, expressive concrete, cantilevered forms, and statement spans. Our team combines structural rigour with architectural ambition across NZ and Australia.

Why choose us

Architecturally exposed structures require an engineer who thinks like a designer. Our team understands that connection details, member profiles, and material choices are architectural decisions as much as structural ones.

What we offer

Architecturally exposed structural systems

Exposed steel, concrete, and timber structures engineered to meet architectural intent.

Canopies, pavilions & public shelters

Lightweight and long-span canopy structures for public and commercial environments.

Landmark & statement buildings

Complex structural solutions for signature architectural forms and civic landmarks.

Adaptive reuse & building conversions

Structural assessment and upgrade of existing buildings for new architectural purposes.

Sustainable & passive design principles

Structural systems designed to support passive solar, thermal mass, and low-carbon outcomes.

3D modelling & visualisation

Structural BIM models and rendered visualisations to communicate design intent clearly.

Residential engineering

Engineering

Residential Engineering

From foundations to roof framing, we provide complete structural engineering for residential projects across New Zealand and Australia — calculated to code, documented to consent standard, and built to last.

Why choose us

Our residential engineers are embedded in the same team as our architects — so structural decisions are made early, not retrofitted. This saves time, money, and redesign headaches for every client.

What we offer

Foundations, slabs & subfloor systems

Design of shallow and deep foundation systems to suit site conditions and loadings.

Waffle raft & timber pile design

AS2870 & NZS3604-compliant waffle raft and timber pile foundation solutions.

Retaining walls & slope stabilisation

Structural design of gravity, cantilever, and anchored retaining systems.

Seismic & wind load assessments

Site-specific seismic and wind demand calculations to NZS1170 and AS1170.

Structural peer review & LIM reports

Independent peer review of structural designs and LIM report assessment advice.

PS1 & PS4 producer statements

Design and inspection producer statements issued by our CPEng-registered engineers.

Commercial & Industrial
05 / Engineering
Engineering

Commercial & Industrial

From steel-framed warehouses to complex multi-storey commercial buildings, we deliver structural engineering that performs under the most demanding conditions — on time, on budget, and fully compliant with NZS and AS standards.

Why choose us

Commercial and industrial projects demand engineers who understand buildability as well as structural theory. Our team has delivered hundreds of commercial structures and knows how to keep projects moving through consent, procurement, and construction.

What we offer

Steel & concrete frame design

Multi-storey steel and concrete frames designed for commercial, office, and mixed-use buildings.

Industrial warehouses & factories

Portal frames, tilt-up, and hybrid structural systems for large-span industrial buildings.

Mezzanine floors & platform structures

Structural design of internal mezzanines and elevated platforms for commercial and industrial use.

Tilt-panel & precast construction

Engineering of precast and tilt-up concrete panels for cost-effective industrial and retail builds.

Seismic strengthening & retrofits

Seismic assessment (%NBS) and structural upgrade design for existing commercial buildings.

Fire engineering coordination

Structural input into fire engineering reports and passive fire protection detailing.

Civil & Infrastructure
06 / Engineering
Engineering

Civil & Infrastructure

We engineer the structures that underpin communities — drainage systems, bridges, retaining walls, and council infrastructure. Our civil and structural team brings deep expertise in NZS and AS standards across both New Zealand and Australia.

Why choose us

Civil and infrastructure projects demand engineers who can navigate complex council requirements and site-specific conditions across multiple jurisdictions. Our team has the experience and credentials to deliver in both NZ and AU environments.

What we offer

Box culverts & drainage structures

Structural design of box culverts, headwalls, and drainage infrastructure to council standards.

Seismic design & earthquake assessments

Infrastructure seismic assessments and design to NZS1170.5 and AS1170.4.

Bridges, overpasses & pedestrian links

Structural design of short and medium-span bridges and pedestrian footbridge structures.

Retaining walls & earthworks structures

Structural design of civil retaining systems from gravity walls to anchored sheet pile walls.

Stormwater & detention tank design

Structural engineering of below-ground stormwater detention and retention systems.

Council infrastructure compliance

Engineering certification and documentation for infrastructure vested to local councils.
