In this episode of Between the Walls, Janey and Penny sit down with Petra Trousilová, architectural designer at JTB Architects and local representative for Architecture + Women New Zealand. From her roots in Prague to her life and work in Wanaka, Petra shares her passion for designing spaces that are not only beautiful but also functional, sustainable, and deeply connected to the people who inhabit them.

They explore the realities of the architectural industry — gender equity, work-life balance, the importance of connection, and the evolving housing landscape in Aotearoa. Petra offers an honest, inspiring look at how architects can lead the shift toward more comfortable, energy-efficient homes built for the future.

What you’ll hear in this episode:

• Petra’s journey from Prague to Wanaka, and what drew her to architecture.
  
  
• How public transport, cities, and people-watching shaped her design philosophy.
  
  
• Insights into her work with JTB Architects, including experience in mass timber and sustainable construction.
  
  
• The mission behind Architecture + Women New Zealand and how it’s helping bridge the gender gap in architecture.
  
  
• Why flexibility, mentorship, and connection are crucial for women in the profession.
  
  
• The challenges of the current housing landscape in New Zealand — from cold homes to short-term building mindsets.
  
  
• How airtightness, ventilation, and thoughtful design can make homes healthier and more efficient.
  
  
• Why collaboration and community are essential — and how networks like the Architecture & Design Library are helping foster that.
  
  
• Petra’s thoughts on AI in architecture, and how it might streamline the work designers love least.
  
  
• What excites Petra about the future of the industry — and why change is already underway.

Memorable moments:

• Don’t be so self-conscious and don’t have such self-doubt. Women have that more — and it holds us back.”
  
  
• “Connection is one of the most important things in this journey of life.”
  
  
• “If we design buildings that are comfortable to live in, we also reduce people’s bills — that’s real impact.”
  
  
• “We don’t have to go from code-minimum to passive house overnight — but we do need to design for the future.”
  
  

Petra’s advice for young designers:

• Be confident — share your achievements proudly.
  
  
• Build connections and networks; they strengthen both your career and wellbeing.
  
  
• Think long-term — design for comfort, sustainability, and community.
