19th-century history meets 21st-century modern oasis. ✨
Flavin Architects completely reimagined the interior of this five-story Federal-style brick row house in Boston, transforming it into a warm, clean sanctuary designed for ultimate relaxation.
The absolute showstopper? The stunning, minimalist floor-to-ceiling windows by Panoramah supplied by SBS OneSource, which flood the historic structure with natural light while keeping the aesthetic sleek and seamless.
Proof that you can honor the past while living beautifully in the present. 🏙️
Drop a 🤎 if you love this blend of historic and modern.

High performance meets stunning architectural design. 🌊🏡
Checking in on this incredible Will Traubel project in South Dartmouth, MA. This build is a total masterclass in combining premium aesthetics with heavy-duty building science.
Here’s a look at the standout specs making this envelope a powerhouse:
🪟 Loewen Windows: Featuring a flawless, custom interior factory finish and custom-tailored jamb depths for crisp, high-tolerance lines.
☀️ Triple-Glazed Doors: Maximizing natural light and views while significantly driving down the HERS rating for peak thermal efficiency.
🪵 Accoya Wood Rain Screen: The ultimate choice for coastal durability, offering unmatched stability against the elements without sacrificing that gorgeous natural wood look.
From the standing-seam metal roof to the precision siding, no corners were cut on this one.
🛠️ Builder/Design: Will Traubel
📍 Location: South Yarmouth, MA

Passport: Stamped. ✈️ Experience: Unforgettable.
We’re taking you behind the scenes at the @panoramah_windows factory in Portugal! 🇵🇹 We recently toured their state-of-the-art facility with some of our architectural partners so they could see exactly how the world’s most minimalist windows are made.
It’s not just about the "look"—it’s about the incredible engineering that allows for massive walls of glass with nearly invisible frames. Seeing the scale of this operation and the precision of the team in Portugal has us more inspired than ever to bring these designs to life back home on the Cape. 🌊🏠
Which would you choose: a massive sliding glass wall or a seamless pivot door? Let us know in the comments! 👇
