About PTX

We are David Gibson and Melanie Hoessle, the co-founders of PTX Architects. We first met in 2001 while working in architectural practices in Melbourne, where we bonded together thanks to our common sensibility and passion for design. In the two decades since, we have lived, travelled and worked together throughout Australia and Europe.

Boasting over 38 years of experience between us, we have worked for multiple award-winning architectural practices, and developed a diverse range of expertise to create sustainable and site-responsive residential, public and community architecture.

We are passionate about architecture’s role in developing deeper connections between built landscapes, the natural environment and the wider community.

We launched PTX Architects in 2006 and relocated two years later to Denmark, on WA’s picturesque south coast. With deep roots in the local community, we have built our philosophy on a reverence for place, and the importance of finding harmonies between our clients’ needs and the landscape they live and work in.

We specialise in creating bespoke residential, public and community architecture that reflects and responds to the landscape around it, and our clients include individuals and families, and large commercial and community organisations.

Designing for our local community

We have specialised expertise in helping local community organisations to realise their vision for new buildings, facilities and spaces. We do this by guiding them through an extensive process over several years. It starts with visualisation and defining the brief, which leads to master-planning and concept design.

The drawings and proposals that result from these stages can then be used to help our clients to secure capital and grant funding for the project. Once funding is confirmed, we proceed to detailed design and documentation, to obtain the necessary council and building approvals.

In the final stage, we act as our clients’ trusted adviser to guide the tender process and engage a suitable construction contractor, and then we oversee the construction itself, ensure that the final result meets - and often exceeds - our clients’ expectations.

Our architecture responds to its location

Our work is inspired by the diversity of the local environments of the South Coast and South West regions of WA and has won multiple awards in both architecture and construction categories. We have delivered projects from the Margaret River region through to Albany and we are experienced at providing services for remote locations. We are currently working on a range of residential, public and community projects in Albany, Denmark and Dunsborough.

B.Sci.Eng (Arch), Dipl.-Ing.(FH)

Melanie was born in Munich and graduated from the University of Applied Sciences Würzburg-Schweinfurt in 2004 with an Engineering degree, specialising in Architecture.

Melanie grew up in a small town south west of Munich close to the German Alps and spent much of her childhood outdoors, often on horseback, exploring nearby forests and landscapes. Moving to the south coast of Western Australia has given Melanie the opportunity to connect with a unique and unspoilt natural environment that she enjoys sharing with her family and equine friends.

Melanie has worked for award-winning architectural practices across Australia, including Wood Marsh in Melbourne and Taylor Robinson in Perth, taking part in such projects as the Australian Centre of Contemporary Art in Melbourne and the Scotch College Design and Technology building in Perth.

With a strong focus on environmentally sustainable design, Melanie is adept at responding to a project’s brief with clarity and vision, balancing each project’s looks and performance with the practicalities of construction.

As PTX's Design Director, Melanie also manages the practice and is responsible for coordinating the client deliverables - design and documentation - for each project. She also ensures that all of the architectural intent - which is detailed in the drawings - is delivered by the builder on-site during the construction phase.

B.Env.Des, B.Arch (hons), RAIA, ABWA

David was born in Perth and graduated from the University of Western Australia with honours in Architecture in 2000.

David considers himself lucky to have spent his childhood holidays surfing and exploring the Great Southern and South West regions of WA. Moving to Denmark as an adult has enabled him to reconnect with those fond childhood memories, and to share the region’s beautiful natural environments and lifestyle with his family.

He previously worked for architectural practices in Perth and Melbourne including the award-winning firms Bollig Design Group and Woods Bagot. Before establishing PTX Architects, David spent three years in the UK working on high-profile projects for renowned international practices Foster + Partners and Rogers Stirk Harbour + Partners.

David is adept at conceptualising and conveying a singular design vision, and he uses 3D modelling and visualisation tools to communicate the look, feel and functionality of each project. These digital tools help our clients to understand all of the intricacies of the proposed project during the design phases, and help to refine the design so that it meets their needs and aspirations.

As PTX Architects’ chief project manager, David coordinates all of the specialist consultants that may have input into your project - these include engineers, quantity surveyors, sustainability and accessibility experts, landscape consultants etc. He also manages the approvals processes to obtain the necessary permits, and oversees project procurement - the appointment of your preferred construction contractor - before monitoring the construction and handover, on behalf of our clients.

We are grateful for the recognition that our projects have received, both from architecture and construction awards programs. We’re especially grateful to the builders and construction contractors - and all of the collaborators and suppliers we’ve formed strong relationships with over the years - who have helped us to realise our clients’ vision and to produce buildings worthy of such accolades.
