OUR TEAM

 

Rosalie Pech Eva

Founder & Practice Advisor

Rosalie is the visionary behind ORA, having founded the practice over 14 years ago to bring high-quality architectural design to regional Western Australia. Born and raised on a farming property near Gnowangerup, Rosalie’s approach is rooted in the practical, “can-do” spirit of the country. In May 2026, after over a decade at the helm as Director, Rosalie transitioned into the role of Founder & Practice Advisor, where she continues to provide her deep expertise and strategic guidance to the ORA team.

Rosalie’s unique background—initially studying Arts and Law—gives her an invaluable understanding of the property and contract issues that underpin successful projects. She graduated from the University of Western Australia with First Class Honours in Architecture in 1991 and was registered as a Practising Architect (#2150) in 2007.

Following several years in metropolitan firms and the local government sector, Rosalie returned to her roots. In 2010, she began practicing under her own name before establishing the Office of Regional Architecture (ORA) in 2012. Under her leadership, the practice has grown into a dedicated team servicing local government, community not-for-profits, commercial, and residential sectors across the Wheatbelt, Great Southern, and South West regions.

Rosalie continues to live the life she designs for, residing on a farming property just outside of Brookton with her family. She remains deeply passionate about contemporary, sustainable, and modest design that reflects the unique experience of living in regional Western Australia. As Practice Advisor, she ensures that ORA’s foundational commitment to the “Regional way of working” remains at the core of every project.

tuan ngo – director

Tuan is a registered architect whose work across a diverse range of projects has been recognised with numerous industry awards. Since joining the practice, Tuan has fully immersed himself in the “Regional Architect” ethos, bringing a resilience and enthusiasm that mirrors the communities we serve. His promotion to Director in 2026 marks an exciting new chapter for ORA, where he continues to lead projects with a focus on creative, frugal architecture and regenerative design.

Tuan graduated from Curtin University with a Master’s thesis exploring the intricate relationship between humans and nature. His passion for urban ecology is backed by his status as a qualified Horticulturalist, providing ORA with specialist knowledge in Australian native flora and endemic species for our landscaping and rural projects.

Beyond his architectural and botanical expertise, Tuan is a qualified chef—a background that proves invaluable when designing highly functional hospitality spaces. He is also a master of the sourdough loaf, a skill refined during the 2020 lockdowns.

Drawing on his upbringing in Vietnam—from the bustling streets of Ho Chi Minh City and Hanoi to his father’s rural town in Nghe An—Tuan brings a unique perspective to his practice. He is a firm believer in the power of community-led development and the beauty of resourceful design.

When he isn’t in the studio, you’ll find Tuan exploring local trails on his bicycle, tending to his family vegetable patch, or managing a community herb garden and a giant compost heap. He also enjoys tackling home renovations—most recently, a custom-built chicken coop.

Milhan Ahmed -Graduate of Architecture

Mil is a Graduate of Architecture from Curtin University with a deep interest in site-responsive design and the evolving relationship between nature and the built environment. Since joining ORA, she has brought a fresh perspective to our regional projects, driven by a curiosity for new ways of thinking and a dedication to creating truly meaningful spaces for our communities.

Mil is particularly skilled in exploring digital workflows, using modern tools to enhance the design process and bring architectural concepts to life. Her proactive approach to learning ensures she is always at the forefront of contemporary practice, finding innovative ways to solve the unique challenges of regional design.

True to the hands-on spirit of the ORA team, Mil’s creativity extends well beyond the studio. Outside of work, she is most at home when she is making—whether that’s cooking, baking, or building small furniture projects. If it involves working with her hands and being in nature, she’s likely into it. Her practical, “maker” mindset perfectly aligns with our commitment to functional and resourceful regional architecture.

SERVICES & SOLUTIONS

PROCESS

To get the best results for our Clients, we have developed a straight-forward, easily navigated process:

  1. On contacting us, we interview you, either over the phone or via our online Project Enquiry Form, to obtain sufficient information about you and your project in order to assess how we can find solutions to the particular issues you face. If we cannot assist you with your particular project, we undertake to refer you to alternative service providers who may specialise in your area of need.
  2. If we assess that we are able to make a valuable contribution to the success of your project, we develop a Scope of Services outlining all the tasks that are involved to arrive at an appropriate solution for it, together with a Fee Proposal setting out your financial investment in that solution and the terms and conditions by which we undertake our work.
  3. You then consider our no-obligation proposal, and if satisfied that we are able to assist you, we sign a Client-Architect Agreement setting out everything that is involved for both parties.
  4. We undertake the work involved as set out in the Scope of Services, with your approval obtained at every stage of the process.
  5. The stages involved are as follows:
    • Preliminaries
    • Feasibility Study
    • Concept Design
    • Schematic Design
    • Design Development
    • Construction Documentation
    • Contractor Selection
    • Contractor Administration
    • Post Construction Services
    • Additional services may be provided if necessary by arrangement
  6. We co-ordinate any specialist consultants required (structural, mechanical or hydraulic design, Building Code of Australia compliance, land & quantity surveying) and deal with any local Shire authority requirements including Planning Applications and Building Permit documentation.
  7. We obtain competitive tenders for the building work from qualified Builders and administer the Building Contract during the construction period and beyond

This process works well because it is detailed, comprehensive and thorough, all due diligence investigation is done and no regulatory or compliance issues are overlooked. We provide you with checklists and regular updates to show you how your project is progressing, and you will always know what is coming next, the timeline and the costs involved. Furthermore, we work to an agreed budget for cost of the building work at every stage, so certainty is assured.
