For Paul Ciolli, founder of Six10 Modern, it all began in Glenbrook Valley— Houston’s largest and most intact neighborhood of Ranch and Mid-Century Modern homes, masterfully designed by the renowned landscape architecture firm Hare and Hare. Paul’s grandmother, Clara Belle, lived in this iconic neighborhood, and visiting her home left a lasting impression. The clean lines, open spaces, and unique architectural details sparked something in Paul at an early age—a fascination with the timeless beauty and endless possibilities of modern design.

Wandering through Glenbrook Valley, Paul saw firsthand how architecture could shape experiences, how light through large windows could define a room, and how thoughtful design could make a house feel alive. These formative memories planted the seed for what would become a lifelong passion: preserving Houston’s architectural heritage while reviving the less traditional through bold, modern design. That inspiration led to the creation of Six10 Modern, Houston's top destination for luxury windows and doors that elevate modern and mid-century homes across Houston and surrounding areas. Paul believes that windows and doors are more than functional elements—they’re the frames through which we experience life, connecting us to our spaces, to nature, and to the city we call home. As a proud Houstonian, Paul is deeply committed to preserving the culture and character of Houston’s neighborhoods, while helping homeowners express their individuality through design that’s authentic, forward-thinking, and built to last.

His own journey began when he and his wife, Gina, built a home inspired by mid-century modern aesthetics. They sought out unique, high-quality pieces that reflected their personality and stood the test of time. Along the way, Paul realized that exceptional design transforms more than just spaces—it transforms lives. At Six10 Modern, we offer carefully curated, high-end windows and doors from leading modern designers and manufacturers, with a focus on clean lines, quality craftsmanship, and lasting performance.

Whether you’re restoring a mid-century gem in Glenbrook Valley, building a contemporary home, or revitalizing a space with a more modern flow, we’re here to help you create a home that’s as unique and enduring as the memories made inside it.

Six10 Modern proudly serve River Oaks, Memorial, Tanglewood, West University, The Heights, Bellaire, Montrose, Galveston, The Woodlands, and surrounding communities including Chappell Hill, Brenham, and Round Top—bringing timeless design and Houston-rooted passion to every project.

Paul Ciolli’s vision is simple: to help you create a home that feels alive with character, filled with light, and grounded in design that tells your story—all while honoring the rich culture of the city he loves.“Live life comfortably and uniquely.”
