✨ Custom Details. Timeless Elegance. ✨

There is something truly special about custom window treatments that bring personality, sophistication, and a beautiful finishing touch to a room.

From the dramatic, patterned bed canopy and rich red upholstery to the exquisitely tailored drapery panels, every detail has been thoughtfully considered.

We especially love the pleated detailing, decorative trim, and elegant hardware that elevate these custom installations. It is these beautiful finishing touches that make a space feel truly one of a kind.

At Greystone Interiors, we believe exceptional design is found in the details. Classic craftsmanship, luxurious fabrics, and thoughtful layering create interiors that remain beautiful for years to come.

A heartfelt thank you to our talented workrooms, installers, and wonderful clients who help bring these visions to life!

✨ Considering custom window treatments or a beautifully tailored interior? We would love to help you create something extraordinary.

Here’s a polished Instagram caption that feels celebratory and design-focused:

A fabulous Thursday in New York City celebrating 100 years of the New York Design Center at 200 Lexington Avenue. ✨🥂

It was such a pleasure spending the day surrounded by beautiful design, creativity, and so many inspiring showrooms and studios.

A few highlights from our day included Ralph Lauren Studio, Made Goods, Thibaut, Christopher Farr Cloth, Pooky Lamps, and Peter Dunham Design Studio.

And such a special detail from Benjamin Moore! An artist personalized canvas bags with our names in beautiful calligraphy, finished with a side tag featuring a Benjamin Moore color, complete with its color name and number. Such a thoughtful and creative keepsake from the day.

Congratulations to the New York Design Center on its 100th anniversary, and thank you to all of the showrooms, artists, vendors, designers, and teams who made Thursday such a memorable celebration. Here’s to a century of exceptional design and many more years of inspiration.

Looking for help bringing timeless, collected design into your own home? We would love to hear from you at Greystone Interiors.

Color has such an impact on how a bedroom feels. 🤍🌿

Soft blues, gentle greens, and warm neutrals create a sense of calm, while thoughtfully layered bedding brings the entire palette together. Here, the botanical pattern adds just enough color and movement, balanced beautifully by cool blue-gray layers and crisp, textural accents.

The mix of pattern, texture, and tone is what makes a bed feel finished and inviting—not overly styled, but collected, comfortable, and serene.

A beautiful reminder that bedding isn’t simply the finishing touch. It can set the mood for the entire room.

A beautiful room can evolve while still honoring the details that have made it special for years.

The window treatments in this space were installed nearly 15 years ago, and once the recent work was completed, it was finally time to select the furniture. The result is happy, bright and wonderfully comfortable, with timeless patterns, fresh color and performance fabrics chosen for everyday living.

We are grateful to our wonderful client, talented contractors and trusted vendors who helped bring this cheerful room together.

It is the thoughtful details and soft layers that make a space feel truly upscale and special. ✨

From beautifully tailored drapery and delicate contrast banding to custom upholstery, layered patterns, elegant lighting, and carefully selected finishes, every element contributes to a room that feels refined, comfortable, and personal.

We love how the soft blue palette flows throughout these spaces, creating a sense of continuity while allowing each room to have its own character.

A heartfelt thank you to our wonderful clients, talented vendors, skilled workrooms, and trusted contractors who helped bring every detail together so beautifully.

A little glimpse of a beautiful transformation still in progress. ✨

Soft striped wallpaper is bringing subtle pattern and warmth to these hallways, while new sheer window treatments offer just the right amount of privacy without sacrificing the natural light. We love how these thoughtful details complement the home’s beautiful original millwork and classic character.

There is still more to come, but it is already feeling wonderfully polished and inviting.

A special thank you to our wonderful clients, vendors, installers, and contractors who help bring every detail together.

✨ Progress is all about the layers.

This bedroom is beginning to take on a softer, more inviting feel with a beautifully upholstered bed, fresh bedding, and elegant furnishings that create a calm retreat. Across the hall, subtle striped wallpaper adds timeless character and depth, setting the tone before you even enter the room.

There is still more to come, and we cannot wait to share the finished transformation. Every detail is thoughtfully considered, and the best is yet to come.

A heartfelt thank you to our wonderful clients and talented trade partners for trusting the process. 🤍

If you are ready to create a home that feels timeless, personal, and beautifully curated, we would love to help.

Favorites from Market ✨

This season, we found ourselves drawn to rooms that feel layered, collected, and full of personality. Rich saturated colors, dramatic patterns, tailored trimmings, and beautifully mixed textures were everywhere, reminding us that timeless interiors are never flat or one dimensional.

From romantic floral wallcoverings and soft sage palettes to bullion fringe, detailed tapes, and warm brass accents, every space felt thoughtfully curated and deeply inviting. We especially loved seeing the return of traditional details paired with fresh silhouettes and relaxed livability.

These are the kinds of interiors that tell a story and truly make a house feel like home. Thankful to all the incredible vendors, artisans, designers, and showrooms who continue to inspire us season after season.

If you are ready to bring layered, timeless design into your own home, we would love to help you create a space that feels beautifully collected and uniquely yours.
