How do you celebrate a long weekend? We’d say: outside.

In honor of the upcoming Labor Day weekend, we’re highlighting a few of our favorite outdoor spaces we’ve designed for gathering, relaxing, dining, and enjoying the landscape. From intimate courtyards to outdoor kitchens and gardens, these spaces extend the experience of home beyond its walls and give us a reason to slow down and spend a little more time outside.

How do you design a home that truly belongs to its site?

For us, it starts with understanding the land. These study models represent two very different custom residential projects: a bespoke home near Rock Creek Park that engages with its sloped site, opens toward the park, and draws the landscape right up to the front door, and a new development of three single-family residences set within a dramatically sloping site.

Physical study models are a unique tool that allow us to explore the relationship between topography, scale, and massing in a way that drawings alone can’t always capture. From early studies to refined design decisions, these models are part of our process for designing custom homes that respond thoughtfully to both the site and the people who will call them home.

Which direction would you take this waterfront home? 🛶

For this custom renovation project currently under construction in Edgewater, MD, we developed four distinct exterior palettes to explore how we could bring new life to this unique home.

1 | Coastal Grey: Refined tones of grey create a clean, modern look.
2 | Pops of Red: Red accents call back to the original red siding, connecting the home’s past with its future.
3 | Green Wash: A deep sage wash unifies the entire facade, existing and addition.
4 | Warm Modern: A rich, warm palette adds depth and character.

One day. Three projects. Three very different scales. 🏗️

Last Friday, our construction site visits took us from a downtown office fit-out to a waterside home renovation to an affordable housing community. No matter the project scale or type, our focus stays the same: staying close to every detail as a design moves from drawing to construction. From reviewing details in the field to working through the unexpected, Construction Administration is where design decisions come to life.

What separates a good project from a great one? For us, it’s embracing the tricky parts. As Charles puts it, “We love design challenges—that’s when a project comes to life.”

We’re honored to be featured in the Home&Design’s Top 100 Designers, with a look at some of our favorite projects from the past ten years, including our Dupont Circle row house renovation, Missing Middle homes, and Midcentury Redux alongside some of the region’s best.

Did you know July 30th is National Intern Day? 🎉

This week we’re celebrating Morgan Waterman, our summer intern and a fifth-year architecture student at Virginia Tech, heading into her thesis year this fall.

Originally from Columbus, Ohio, Morgan has spent the summer diving into professional practice, picking up new skills, and exploring a new city along the way. At the core of her design approach is the belief that architecture should be for people and place, designing with the people who’ll use a space, not just for them. When she’s not out exploring DC, you can find her crafting, reading, or simply searching for the best coffee shop.

Thank you, Morgan Waterman, for all you’ve contributed to the Teass \ Warren team so far! Scroll through to check out some of her latest work.

How do we design commercial spaces to not only house a business, but become a reflection of our clients’ brand?

That’s the question we seek to answer through our Business-Place practice. From creating an intimate sister space for O’Sullivan’s Irish Pub (O'Sullivan's Irish Pub) with The Snug, to designing a warm and welcoming new home for DCanter (DCANTER: Your Neighborhood Wine Concierge) in Alexandria, we help small businesses launch boldly, connect with their communities, and grow with intention.

What does it mean to preserve history while creating something new? For us, it’s projects like The Collection at R Street.

We were honored to celebrate at Virginia Tech ‘s Innovation Campus as The Collection at R Street received an Award of Merit in Historic Architecture from AIA Northern Virginia. The project transforms a historic 1880s schoolhouse through thoughtful adaptive reuse, creating twenty-three modern homes that expand missing middle housing opportunities while preserving a valuable piece of DC’s architectural heritage.

By pairing historic preservation with gentle density, The Collection at R Street demonstrates how existing buildings can help address housing needs, strengthen neighborhoods, and connect new residents to the city’s rich architectural history.

Where are you watching the World Cup? ⚽️

At our recently completed expansion at O’Sullivan’s, we worked to create the Snug. Traditionally, a snug is a small, highly private, partitioned alcove within an Irish pub, often featuring opaque or etched glass and its own dedicated service hatch to the bar.

In this case, our client expanded into the adjacent retail space with the goal of creating a distinctly different experience for a diverse customer base, a place that’s a bit quieter, where you can catch up with an old friend over a pint (or two).

Custom millwork, rich finishes, and elegant lighting fixtures all come together to shape the experience, where material, detail, and light define a space that feels both intimate and intentional.
