Thinking back to last Friday at the 2026 AIA Conference on Architecture and Design, Will and Charles checked out a few standout projects during the tour segment.

🌊At the Center for Coastal Studies at Scripps, they explored how Miller Hull approached adaptive reuse within the strict constraints of the California Coastal Commission. The project preserves the carbon investment of the original concrete storage tank while transforming it into office and collaborative spaces, aligning with workplace and adaptive reuse themes relevant to our own office.

🌴At TreeHouse, a new market-rate multifamily development in Banker’s Hill, they examined design strategies for urban residential projects with views of San Diego Bay. The visit highlighted key considerations such as integrating amenities like a pool and roof deck on a compact site, as well as the detailing complexities of combining wood framing with concrete construction in a podium configuration, insights applicable to our clients in the DMV area.

☀️In La Jolla, they visited two cultural buildings that highlight the role of placemaking and design in connecting arts organizations with their audiences: the renovated and expanded Museum of Contemporary Art San Diego and The Conrad, the new home of the La Jolla Music Society.

DC’s alley lots just got a major zoning update. But what does it actually change for development on these sites?

Last fall, we published a piece on the challenges of DC alley lot zoning and development, noting the advocacy efforts of principals Will Teass (via ) and Charles Warren (via ) in advancing proposed amendments through the public hearing process.

Now, following the DC Zoning Commission’s adoption of those amendments in March, we’re taking a closer look at what has changed in our latest TWA Journal post.

Read more via the link in our bio to learn what improved, what challenges remain, and how these often-overlooked parcels could play a larger role in the future of housing and infill development in Washington, DC.

Are visualizations required for the approvals process?

In short, yes. Visualization is not a luxury; it is essential to moving projects through the design and approvals process effectively.

Our renderings for a seven-unit building in the Dupont Circle Historic District demonstrate why. By bridging the gap between technical drawings and lived experience, visualizations make a project legible to decision-makers, neighbors, and review boards alike.

They communicate value through scale, context, and atmosphere in a way that plans and sections alone simply cannot. And in a process where perception matters as much as compliance, that clarity is what builds understanding, trust, and ultimately approval.

How do you build more housing in Arlington?

When our client () set out to increase the number of units on a single-family lot, we partnered with them for over five years, including more than two years in a site plan process typically reserved for much larger projects.

The result is a building that fits within the scale of its neighbors, reads as a pair of homes rather than a multifamily project, and demonstrates that missing middle housing doesn’t have to be a compromise. Good design and responsible density are not opposing forces. This year’s award we received is proof of that.

But this project also highlights a broader issue: if we want more “missing middle” housing, our policies and processes need to align with that goal. When small-scale infill is subject to the same timelines and entitlement hurdles as much larger developments, we limit the very outcomes our plans are meant to encourage.

We’re proud of what this team accomplished together and hope it contributes to an ongoing conversation about how Arlington can better support thoughtful, well-designed infill housing. Congratulations to all of this year’s DesignArlington winners!

10th opening of !

Arthub609 is pop-up art gallery that blossomed from the creative collaboration between and during the design of our office. Instead of opting for a traditional reception area, we decided to carve out space for up-and-coming artists to showcase their work in a vibrant, quasi-gallery environment. It’s been wonderful seeing the gallery take shape and become a platform for artistic expression.

Tonight marks our 10th opening, and we’re thrilled to welcome and her captivating collection, “Cellular Drift,” to ArtHub609. This event promises to be a lively celebration of creativity and community, and we’d love for you to join us. We still have a few tickets remaining. If you’re interested, please visit the Eventbrite link in our bio to reserve your free spot.

Looking forward to seeing you at ArtHub609 and sharing this special evening together!

Postcards from Spain! 🇪🇸💌

Charles has been exploring centuries-old cities throughout Spain, where historic architecture exists alongside contemporary interventions and evolving spaces still maintain a strong sense of identity and place. These environments resonate with much of our own work throughout historic neighborhoods across the DMV, where designing within historic contexts requires careful consideration of scale, materiality, and continuity between past and present.

These spaces remind us that thoughtful architecture is not about replicating history, but contributing to it in a way that feels both contextual and forward-looking.

What can traveling abroad teach us about architecture and design?

Principal Charles Warren is currently visiting Spain, exploring spaces and products that highlight innovation in materials, fabrication, and detail. From immersive factory / showroom tours to the streets beyond, experiencing architecture abroad is a great reminder that design is shaped not only by what we create, but by what we observe: how materials perform in context, how spaces are experienced, and how ideas translate across cultures.

And of course, experiencing the local cuisine is an added bonus!

The best homes are built in moments like this one.

We spent Friday morning with our clients refining the design of their new home near Rock Creek Park, working through the details that make a house feel like theirs: warm walnut, light oak, sage green, brushed metal, and a stone surface that ties it all together. Piecing together a palette that’s uniquely theirs, with natural materials inside and out for a home that genuinely belongs to its place. This is what the process is all about.

Our office had the pleasure of hosting students from Howard University as they presented their final projects: an exploration of DC public libraries. 📚

The students worked in groups to research and visit a DC library, then individually designed physical models that represented key design elements of their chosen library, including circulation, structure, aesthetics, and spatial experience. The session was a great opportunity for the TWA staff to practice our own critique and communication skills, and a welcome return to diagrammatic thinking and model-making rooted in early design exploration.

Thank you to the Howard students for sharing your thoughtful work with us!
