RDA Architect Anna Scibior Qualifies as a Certified Passivhaus Designer

We are thrilled to announce that Anna Scibior has recently completed her training and examination to become a fully qualified Passivhaus Designer.


Having joined RDA as an Architectural Assistant in 2016, Anna has worked incredibly hard to refine her skills and become one of the most experienced and knowledgeable members of our team when it comes to sustainable design.




This course teaches the core concepts behind the Passivhaus standard, considerations and methodologies for its implementation and the use of the Passivhaus Planning Package (PHPP) for achieving low energy performance.


Which in turn insures that every Passivhaus, Enerphit or low-energy home we design is rooted in proven methodology and assured in its success.


‘Although the course and examination were challenging, it was incredibly worth it to gain the knowledge and experience necessary to continue building the very best in passive design at RDA.


This practice is known for its proficiency in passive design, which is why I joined eight years ago. So, becoming a certified Passivhaus designer is a true career highlight and something I am grateful for RDA for supporting me through.’

NLA Coffee conversation: What are the opportunities for housing on constrained sites?

By Richard Dudzicki • March 10, 2026
On 25 March, Richard will be speaking at NLA’s Coffee Conversation about how London’s most constrained and overlooked sites can play a role in addressing both the housing crisis and the climate emergency. Across the city, small and fragmented plots are often dismissed as too difficult to develop. Backland sites, former garages and leftover spaces within established neighbourhoods are frequently overlooked by conventional development models. Yet collectively they represent a significant and largely untapped opportunity.

Passivhaus Trust - The Old Timberyard: Deep Retrofit, Honest Lessons, Lasting Performance

By Richard Dudzicki • March 3, 2026
There is a particular responsibility that comes with working on an existing building. The Old Timberyard , a former Victorian workshop, offered the opportunity to demonstrate how careful retrofit can honour heritage whilst delivering genuine long-term performance. Behind its retained brickwork and historic fabric sits a carefully executed EnerPHit upgrade. This was not about surface improvements, but a rigorous, fabric-first transformation, reworking a cold, underperforming structure into a comfortable, resilient and low-energy building fit for contemporary use.

Technical Briefing: Passive House Retrofit and Reuse Webinar

By Richard Dudzicki • March 3, 2026
Three weeks ago, Heather Faulding and I had the pleasure of presenting at the NLA’s technical briefing on Retrofit and Reuse a CPD-certified webinar on low-energy & high-performance buildings. It was a fantastic session spotlighting some of the most innovative retrofit work. Heather shared her incredible project for Daily Paper in New York: a powerful example of creative reuse, transforming a crumbling structure using over 7,500 soda cans crafted by local communities. The shimmering façade reflected not only light but the heritage of African beadwork a story of culture and circularity woven into architecture.
