Portfolio Tips to Help You Get Hired: A Guide for Part 1 & Part 2 Architecture Students

By Richard Dudzicki • June 9, 2025
Behind the Scenes: RDA x Sana Open Studio Earlier this month, we had the pleasure of opening our studio doors for a collaborative event with Sana Tabassum- architect, educator, and founder of :scale, a platform that champions emerging voices in architecture. The evening brought together students, graduates, and early-career designers for an inspiring session of portfolio reviews, career chats, and honest conversations about what it really means to navigate the world of architecture today. The studio was alive with creative energy as attendees engaged in one-on-one critiques, informal Q&As, and discussions that ranged from practical job hunting tips to big-picture reflections on the future of design. Sana shared her expertise on building a personal brand, curating meaningful portfolios, and using digital platforms like Instagram and LinkedIn to grow your reach and professional network. What stood out most was the sense of community, an affirmation that spaces like these, where emerging architects can share, reflect, and ask questions, are more essential than ever. 

RDA & London Festival of Architecture : Conversations on Sustainable Living

By Richard Dudzicki • May 8, 2025
RDA Architects is proud to be participating in the London Festival of Architecture (LFA) 2025, with a specially curated event designed to spark dialogue around sustainable design and future-facing housing. As part of this year’s festival, we are hosting “Conversations on Sustainable Living: A Guided Walk Through East Dulwich,” offering the public a rare chance to explore the principles of Passivhaus architecture in real-world residential settings. You can now book your free place via Eventbrite: Conversations on Sustainable Living – Guided Walk Through East Dulwich About the London Festival of Architecture 2025 The London Festival of Architecture is Europe’s largest annual festival of architecture, with hundreds of events that bring together architects, communities, and the public. The 2025 theme, “Voices,” asks how we listen, who gets heard, and how design can empower underrepresented perspectives—whether social, cultural, environmental, or spatial. This theme is especially resonant for us at RDA Architects, where we believe sustainable design isn’t just about energy efficiency—it’s about creating spaces that reflect and respond to the needs of the people who live in them.

Understanding Your Procurement Options

By Richard Dudzicki • April 30, 2025
Finding the Right Path for Your Project At RDA Architects, we understand that no two projects are the same—each client brings a unique vision, set of priorities, and practical considerations. One of the most important early decisions in delivering a successful project is selecting the right procurement route. Whether you're building from scratch, transforming an existing home, or undertaking a detailed retrofit, the procurement method you choose will shape everything from cost and timelines to quality and creative control. Here’s a breakdown of the three most common approaches, along with our perspective on which may work best for your project.
