Aggregate Architecture

The definition of texture: raw brick meets rich grain. We love discovering unexpected, warm moments in the details of design. What’s your favorite element in this sanctuary?

1969 meets 2026

This Trentman House by Hugh Newell Jacobsen is a minimalist dream, but it was facing a nightmare of water intrusion and mold.

The Mission: Gut it. Fix it. Save the aesthetic.

We integrated sophisticated mechanical systems and insulation without disrupting the legendary silhouette. It’s the same award-winning look, now powered by 21st-century tech.

Urban life has its charms, but sometimes you just need to get above it all. Your roof, patio, or courtyard is an untapped sanctuary waiting to be discovered.

You don't need acres of land to have an oasis. You just need the right design. DM us to discuss how we can turn your outdoor space into your favorite "room."

Meet founders, Mark and Lucia Freeman.

When we founded Aggregate Architecture + Design, our goal was simple: to create thoughtful, beautiful, and sustainable spaces that reflect the unique stories of our clients and the soul of their communities.

For us, great architecture isn't just about buildings; it's about the people who live, work, and connect within them. It’s the combination of your vision and our design-thinking. It’s the meeting of functional needs and artistic inspiration.

We use a collaborative approach to pull together architecture, interior design, construction management, and engineering knowledge to shape a space that feels uniquely yours. This philosophy is the foundation of who we are and every project we’ve had to the privilege to work on so far.

Our journey is a shared one and we're so glad you're part of it!
Drop us a DM or check out the link in our bio. We'd love to discuss how our aggregate approach can help you create your ideal space.

We had the privilege of completely re-imagining this stunning home, blending the classic architectural soul of Chevy Chase with a fresh, sophisticated interior. From the tailored millwork in the foyer to a custom-built home gym, every square inch was thoughtfully redesigned to elevate everyday living.

We believe a home should honor its history while functioning perfectly for a modern lifestyle. Your dream home is closer than you think. DM us today.
