Who We Are

Warren and Mahoney is an insight led multidisciplinary architectural practice with six locations functioning as a single studio. Our clients and projects span New Zealand and the Pacific Rim. The practice has over 220 people, comprising of specialists working across the disciplines of Architecture, Workplace, Masterplanning, Urban Design and Sustainable Design. We draw from the wider group for skills and experience on every project, regardless of the location.

Warren and Mahoney has created iconic designs with visionary design leaders. Our founders, Sir Miles Warren and Maurice Mahoney have been recognised as driving forces in introducing Architectural Modernism to New Zealand. Our design philosophy is founded on the belief that human experience is improved through enduring design excellence, delivered through formal simplicity and material quality.


The pursuit of architectural excellence lies at the core of our practice, across a diverse range of interior, building, and infrastructure projects. We believe that the quality of the design of our environment – in all its dimensions - affects the quality of our lives. Our design philosophy is process driven, with each project being informed by contextual analysis and identification of essential, relevant insights. Our architecture seeks to improve the vitality of human interaction and experience through built form.

Workplace Consultancy

Contemporary workplace consulting defines each workplace as a fundamental driver of the success of the organisation it houses. Our interior and architecture disciplines work closely together to create our workplace projects. This collaboration serves the inter-connected analytical, strategic, and creative requirements of our Clients. We see a successful workplace project as first involving the definition of a clear strategic brief. Following this the planning, guided by this brief, of an organisation’s structure and flexible behaviour is followed by the design of an environment that expresses the organisation’s essential character and values.

Masterplanning + Urban Design

Warren and Mahoney has master-planned a wide range of public and commercial environments throughout its history. These range from secondary schools, to campus projects, community cultural and sports centres, as well as mixed use commercial environments. Our master-planning practice has developed alongside the maturing sophistication and depth of the discipline of urban design. Beyond the urban design needs of each building project specific master-planning and urban design commissions have also informed our evolving practice. Our approach is to develop spatial frameworks that reflect the unique cultural and environmental dimensions of each project. We design to provide a high degree of flexibility as a site’s sense of place develops and evolves.

Sustainable Design

Sustainability is a core value of our practice. We believe sustainability is integral to the achievement of architectural excellence. We work with our Clients to identify the environmental potential and goals of each project as early as possible, and then seek out practical means by which to deliver on these goals. Warren and Mahoney has led in the development of sustainable design in New Zealand assisting in the founding of the New Zealand Green Building Council, designing our first Five Star Green Star commercial and tertiary education projects, and becoming New Zealand’s first carboNZero rated architectural practice.

Our Heritage

Being the only third generation architectural practice in New Zealand – Warren and Mahoney have evolved from a generalist firm into a multidisciplinary design practice offering architectural, interior, graphic, urban and environmentally sustainable design services.

Founded in 1955 by Sir Miles Warren in Christchurch, the partnership went on to design buildings that are now regarded as the benchmark of New Zealand Modernism.
Sir Miles was knighted in 1985 for his services to architecture and in 2003 named one of ten inaugural ‘Icons of the Arts’ by the Arts Foundation of New Zealand.

Since 1979, the practice has expanded to Wellington, Auckland, Queenstown, Sydney and Melbourne. Warren and Mahoney has nurtured some of New Zealand’s finest architectural talent. Our people remain key to the remarkable Warren and Mahoney history of innovation and design excellence.

Sustainable Design

Warren and Mahoney achieves the highest environmental standards for its buildings and sets a similar standard for its own environmental performance.

Over the last decade Warren and Mahoney has established itself as a recognised leader in the development of Environmentally Sustainable Design (ESD).  In 2007 Warren and Mahoney became New Zealand’s first carboNZero architectural practice and was recognised in 2009 by the United Nations as one of the first hundred organisations in the UN Climate Neutral Network.

Warren and Mahoney’s  investment in Environmentally Sustainable Design has resulted in not only numerous award winning buildings, but also specialist skills and a unique technical database of information allowing us to provide advice across the myriad of issues which ESD affects.

Sustainability is part of our process  and our completed work ranges from office buildings to libraries, industrial buildings, education, housing and sporting facilities. Warren and Mahoney believes that sustainable design is integral to good design and can be achieved for all budgets and building types.

Warren and Mahoney has been one of the driving forces behind the establishment of the New Zealand Green Building Council and has been actively involved in the technical development and piloting of the Greenstar tools. Warren and Mahoney was involved in one of the first 5 star office buildings in New Zealand, the first 5 star “as built” rated building and more recently the first two 5 star rated education buildings.

Warren and Mahoney’s achievements in sustainable architecture have been recognised in numerous national awards over the past decade. In 2010 buildings designed by Warren and Mahoney were awarded the top NZEE (engineering), Property Council and NZGBC awards for sustainable design.

Warren and Mahoney is committed to leading Building Information Modelling (BIM) in the design and construction industry.

Our BIM leadership team has proven local and international expertise and experience in the delivery and coordination of large complex projects using collaborative BIM workflows and technologies. We have experience on projects involving high density building services and specialist building requirements, including the utilisation of clash detection, project briefing, space-planning and room data sheet reporting. Additional BIM services include fabrication and on-going facilities management (FM) technologies.

Our BIM expertise helps clients better understand the implications of the design at earlier stages of the design process and delivers construction cost savings and reduces construction delivery times.

Our BIM teams understand and work with local and international industry guidelines, standards and protocols for the integrated delivery of BIM enabled projects. These include the New Zealand BIM Handbook, New Zealand BIM Schedule, the Australian National Specification System (NATSpec) BIM protocols, the Australian and New Zealand Revit Standards, the Australian Institute of Architects, the American Institute of Architects, the Royal Institute of British Architects and the Singapore BIM Standards and the Construction Operations Building Information Exchange (COBie) and Industry Foundation Classes (IFC) data information exchange protocols.

Our project specific BIM Management Plans (BMP) are developed in consultation with and tailored to the individual BIM goals and aspirations of each client and project. Defining the project BMP at the outset of each project lays the technology and workflow foundations on which the overall BIM deliverables and project stakeholder responsibilities can be agreed, reducing the potential for unforeseen risk to our clients.

Workplace Diversity

Warren and Mahoney places a  strong emphasis on fostering a diverse workplace and inclusive culture. We are committed to the principles and practice of equality, and  make appointments on merit. We recognise the employment aspirations of women, Maori, Pacific Island, other ethnic and minority groups, people with disabilities, to ensure fairness in employment for all people and groups of people.

All managers and staff have a responsibility to promote a work culture in which all staff, whatever their gender, ethnic background, social background, sexual orientation or role, are valued, treated equitably and with respect.

Integrated Management System

Warren and Mahoney has implemented an Integrated Management System (IMS) that has been audited and certified as compliant with ISO9001 – Quality Management; AS/NZS4801 –Safety Management; and ISO14001 – Environmental Management. This meets our philosophy for the pursuit of ongoing professional and architectural excellence.

These standards are internationally recognised as ‘best practice’ and the management of these will allow Warren and Mahoney to mitigate risk by introducing improved processes and technologies through new initiatives developed and legislative changes.  We are bringing quality professional and architectural services to our clients through the integrity of qualified people and secure systems.


Warren and Mahoney places importance on good corporate governance practices for maintaining the direction and proper management of the company. These practices influence how the objectives of the company are set and achieved, how risk is monitored and assessed and how performance is optimised.

The corporate governance structure is designed to encourage entrepreneurism, innovation, development and exploration, to ensure proper accountability and the maintenance of control systems commensurate with the risks involved.
