Inside a $9M Designer Retreat in Dallas

Step into a world where arched stone meets polished brass and sunlight floods every corner. This sprawling 4-bedroom, 5-bathroom home in Knox Henderson takes modern luxury and turns it into an everyday experience. Spread across 5,180 square feet on the fifth floor of The Terminal at Katy Trail, it’s curated by Gonzalo Bueno of X+III—proof that outstanding design doesn’t just happen, it’s thoughtfully crafted.

1. Arched Stone Grandeur Meets Glass

First impressions hit hard with this jaw-dropping entryway. Picture a rhythmic dance of deep, rounded arches carved from warm beige stone, heavy and grounded. Behind them? Floor-to-ceiling glass panes opening up to a sleek modern interior where a dark gray floating staircase takes center stage. It’s a clever play on contrasts—solid texture against airy transparency—with black bollards leading you right up to that inviting door. To get a similar striking balance at home, mix a dense, tactile outer surface with expansive glass for that wow factor that stops people in their tracks.

2. Walnut Entryway with Brass Glow

Warmth wraps around you here like your favorite blanket. Rich walnut wood panels frame the entryway, their grain gleaming under the soft, golden wash of a brass wall sconce. Step through the carved wooden door—classic design, brass hardware—and the cool, white marble floors beckon from inside. This entryway is where old-world craft meets modern elegance in perfect harmony. Recreate the vibe by pairing deep woods with polished stone and throwing in a standout light fixture that glows like a little secret.

3. Ivory Calm on Honey Oak

Soft ivory hues drape the living room, inviting calm and comfort. Curved white armchairs get cozy around a bold black cowhide rug resting on wide honey oak planks—that contrast feels unexpectedly alive. The built-in wet bar quietly gleams with polished stone and glass-front refrigeration, while an abstract painting in quiet blues and greens lifts the space with a subtle splash of color. To channel this serene yet layered feel, marry neutral tones with one statement animal print and bring in warm wood floors that ground the design.

4. Ivory Minimalism with Brass Warmth

Minimalism never felt so inviting. This kitchen’s handleless ivory cabinets fade into the background, letting that dazzling gold range hood take the spotlight. Polished white marble blankets the island and backsplash, their veining adding just the right hint of depth. Warm, herringbone oak floors cozy things up, while matte brass fixtures and sleek bar stools sharpen the look. Try this at home by choosing flat-panel white cabinetry and mixing warm oak with metallic touches for a kitchen that’s both clean and rich at once.

5. Crisp White Dining with Glass Walls

Breakfast in a sun-filled room? Sign us up. Crisp white upholstered chairs with dark legs surround a hefty concrete table anchored by a soft gray-and-white patterned rug that adds quiet texture. Floor-to-ceiling glass windows framed in dark metal flood the room with city views and natural light, the perfect stage for that sculptural chandelier with candle-style bulbs glowing warmly overhead. This space whispers style with volume; combine a statement concrete table with light seating and uninterrupted glass to keep it bright yet grounded.

6. Silver Gray Bedroom with Nailhead Charm

If tranquility had a room, this would be it. Cool silver-gray walls set a soothing mood, grounded by a large abstract rug underfoot. The star here? A white upholstered bed with subtle nailhead trim that nods to classic craftsmanship without overwhelming. Pillow layers in light grays mix with a rumpled white duvet for that “just got out of bed” luxury. Warm wood floors and a dark dresser anchor the space, while a round metallic mirror and subtle recessed lighting keep things airy and polished. To draw this softness into your room, blend neutral palettes with textured upholstery and well-chosen accents.

7. Brass Framed Soaking Oasis

Soaking tubs don’t get much cooler than this. Surrounded by floor-to-ceiling glass panels accented with brushed brass frames, this bathroom invites the city skyline right inside. The white freestanding tub sits on light beige stone tiles, complemented perfectly by a tall polished chrome floor faucet. A small wooden side table with fresh flowers adds a graceful softness to the otherwise bold design. For a hint of this luxe spa feel at home, lean into large windows with metallic frames around your tub to bring the outside in and keep bathing light-filled.

8. Walnut and Glass Study

Escape here, where deep espresso walnut pairs effortlessly with glass and metal. A wooden credenza anchors the space, balancing the sleek glass-topped desk with its black metal base. Dove gray walls and light oak floors breathe calm beneath a bold navy, gold, and white abstract canvas. Add a sculptural white lounge chair for moments when work turns to rest. A natural cowhide rug softens the polished floor, making work feel less like a chore and more like a retreat. Bring this feel to your office by choosing one bold dark-wood piece against a light neutral palette.

9. Slate Brick and Glass Patio

Outdoor living gets an upgrade here. Feel the joyful contrast of textured white brick meeting expansive transparent glass walls. A round concrete dining table anchors the terrace, surrounded by slate blue sculptural chairs that bring a geometric pop of color. Large gray floor tiles stretch the clean-lined look, while simple black sconces cast gentle pools of light after dark. The result? Relaxed polish perfect for everything from lazing to lively dinners. To replicate, pair neutral masonry with bold-colored seating for a vibe that’s grounded but full of personality.

10. Sunlit Terrace with Woven Wicker

Picture lounging on two sleek black-framed chaise lounges, thick off-white cushions inviting you to stay a while. The terrace’s large gray porcelain tiles mirror the bright Texas sky above, spreading clean and open vibes. Bronze metal railings cradled by tall ornamental grasses soften the sharp modern lines. Inside, through glass doors, dark woven wicker chairs and a matching table suggest cozy al fresco dinners when the sun dips down. This is the kind of terrace that whispers “slow down.” To get the look, pair neutral seating with soft greenery to balance clean architecture.

Final Thoughts

This isn’t just a $9 million Dallas home—it’s a masterclass in balancing textures, tones, and light to create spaces that feel both grand and deeply livable. Each room invites a claim, but if it were mine, I’d stake a claim on that soaking tub with a city skyline view—or maybe the cozy walnut-wrapped study when work calls. Which space speaks most to you?
