Finishing touches make all the difference! Our clients in Reston asked us to find a tile for their kitchen backsplash that would complement their existing metallic mosaic tile behind the range. We found a stunning dark gray metallic tile with a textured starburst pattern and it works perfectly with the existing tile and quartz countertops.

Your "She-Shed" or "She-Cave" doesn't have to be a hidden space in the basement or in the backyard. Repurpose an existing room and make it your own like we did for this client in Fairfax. With a comfortable, plush sofa in a slate blue, she can relax and read, prop her feet up on the ottoman, while drinking some tea and planning the day. A beautiful wallpaper and custom window treatments make the space feel extra special.

We hope everyone is enjoying their holiday!

Traditional foyer gets a complete Mid Century Modern Makeover! (Scoll to see the befores)

To begin, the existing slate floor was replaced with oversized porcelain tile flooring. Natural oak railings were painted black and wood balusters were replaced with wrought iron, which really brought the Mid Century Modern aesthetic to life. Oak stairs were replaced with 7 3/4" rocking horse white oak hardwood by Mirage Floors. The space was brightened with the addition of new light fixtures, recessed light, and the installation of modern mirrored doors that replaced existing standard closet doors.

Sheers with a hint of gold add softness to this primary bedroom while still letting the view in.

Is your powder room ready for guests? Make it a space that reflects your style with a beautiful vanity, mirror, fixtures, and lighting. In this newly updated bath, we selected a navy lacquered vanity and coordinating mirror and paired it with gold hardware, plumbing fixtures and towel holder. We found the most stunning wallpaper with a gold geometric design to grace the walls.

This serene screened-in back porch is the perfect setting for entertaining and family dining. The table can accommodate 8 people normally and up to 12 by using the two self-storing leaves. And a comfy sectional offers a spot for conversation or simply reading a book and enjoying the afternoon.

08/12/2022 that's a gorgeous bedroom! We LOVE the wallpapered ceiling and how inviting is the chaise lounge by the fireplace? It's the perfect spot to relax and read a book!

This weekend we learned that it truly is a small world!

When a friend of Sandra Hambley's posted the gorgeous view her family was enjoying at a Smith Mountain Lake home they were renting she thought it looked incredibly familiar. After exchanging messages, Sandra realized it's the same vacation home that she assisted with the design of multiple bathroom remodels earlier this spring!

An updated kitchen for the property will be coming next season.


In this McLean home, we converted a dining room into a pole dancing studio! Pole Dancing is a performance art that combines dance and acrobatics centered on a vertical pole. We added beautiful gold sconces to add much needed lighting and mirrors which were customized to fit perfectly inside the existing trim.

Remember when we shared the inspiration for this spa bath's custom vanity? Well, here's the finished space! This was a complete bath remodel and everything is new. Also notice the beautiful wall mural and beautiful new tile shower. You can scroll through to see inspo photo for the vanity.

We photographed six homes this week and can't wait to show you the finished spaces! Here's a little sneak peek of what's to come!


Happy 4th!


Another finished space in our Adams Morgan client's condo. We created a multifunctional guest room and office space featuring an adjustable height desk, office chair, beautiful new artwork, area rug, and queen size wall bed with integrated love seat. Simply remove the back cushions of the love seat and the bed lowers directly over the seat cushions. Voila!

Happy Father's Day to all the Dad's out there! We hope you have a relaxing day celebrating with your families.

Her new primary bath features a stunning tile shower design with a lighted recessed shelf, custom floral mural, new vanity cabinetry & countertops, new tile flooring, wall sconces, chandelier, floating shelves, and fixtures.

We always enjoy assisting clients with making selections for their new homes. Last week, Janet LaValle Aurora and Catherine, from the builder's design center received this wonderful feedback on the experience.

Janet and Catherine,

Thank you so much to you both for all of your insight, professional artistry and assistance during yesterday’s long session at the Decor Center.

You are both skilled professionals with great talent and familiarity with how to move the process along for customers like us, who walk in with only a few choices selected and a completed unfamiliarity with the process.

We felt that your respective contributions in bringing out our tastes and preferences, identifying options, and guiding us in our decision-making were extremely valuable. We believe we benefited even more from the synergy created by your combined contributions.

Back in April we shared a photo from one of our installation days on this fireplace niche project. Here's the final result!

We added custom sized shelves, wallpaper, and lighting to the niches the builder had created flanking the fireplace wall. Before we did this, they were just dark areas on each side. ⁣Swipe to see “Before” photo.

Designed by Janet Aurora.


We love this custom mural we installed as part of a complete bathroom remodel. It adds some drama and complements the teal cabinet hardware and tiled shower design. Stay tuned to see more photos of this remodel.

Breathe new life into a well-built chair by reupholstering it! We reupholstered these beautiful black lacquered chairs with a vibrant floral pattern that easily transitioned into our client's art deco style living room. Swipe to see the before photo.

How do you want your home to feel? And how can it reflect who you are, where you have been and encapsulate your favorite experiences? My design mission and philosophy is to uncover and then enrich and elevate a client's natural style.

This modern style home began with new luxury vinyl plank on a concrete slab to unify a modest first floor after removing walls in the dining room and kitchen. The best part of this project was transforming an otherwise ordinary home by using color and our client's most valued collections from over a decade of living in and around the Middle East. Our client loves her home so this is a design success.

We also remodeled the kitchen and updated bathroom tile and will share those finished spaces.


It’s a beautiful night for Sandra Hambley and Heather Drach to attend a graduation cocktail party at 1789 Restaurant for a client’s son, who just graduated Georgetown and is off to law school.


With plenty of comfortable seating for a crowd, this theater/lounge room is an ideal spot to host a Kentucky Derby viewing party!


We can't help but imagine this dining room as the perfect space to host Mother's Day brunch.

SDI is excited to be back at our client's Adams Morgan condo to complete a primary bath remodel. This is our fourth project after completing the interiors of multiple living spaces, the primary bedroom, a powder room, and kitchen update.

Today we are sharing the beautiful selections that were made for her bathroom remodel. You can scroll to see a before photo of the bathroom and an in progress photo of the tile shower installation.

Happy Easter from the Signature Design Interiors team!


Sandra Hambley was recently interviewed for a feature in Northern Virginia Magazine titled "What to Look for in a Home Design for Your Golden Years". Here's what she had to say about the important of color scheme.

Just try to stay away from true grays, says Sandra Hambley founder of Signature Design Interiors in Herndon. “They tend to be gloomy for a lot of people—particularly older people,” she adds.

Instead, you could opt for more of a blue-gray. “Blue is the most universally accepted color as it tends to be soothing to the most number of people, so trying to integrate some sort of blue could be good,” Hambley says. “And white ceiling paint is always a good way to keep things bright.”

Here's a great example of that advice demonstrated by a side by side comparison of before and after photos taken from SDI's current senior condominium project in Gambrills, MD. Our team has been updating the common spaces including the entry foyers, hallways, and gathering spaces in all three of the community buildings with new flooring, lighting, artwork, custom furnishings, and paint.

You can’t let a designer’s home go undecorated for her birthday! SDI designer Heather Drach quietly put these decorations up early this morning on Janet LaValle Aurora's front porch!

Here's a peek at Janet LaValle Aurora's install today. Our client asked us to make better use of the empty niches flanking their fireplace. Look at the BIG difference the new shelving and lighting is going to make!

Lighting adds dimension and accentuates this fireplace design.

This Chantilly kitchen remodel is coming along nicely! Our client really loved the dark cabinetry and lighter countertops of his basement wet bar and wanted to create that same aesthetic in his kitchen. Take a scroll through our photos to see the new cabinetry, countertops and lighting we've put in so far. (Backsplash is coming soon!) You can also see the basement wet bar that served as inspo and the before photo of the kitchen.

Wow! The primary bath in this Alexandria condo turned out beautifully. A complete pull and replace remodel included installing new vanity cabinetry with plenty of storage, new granite counters, lighting, and medicine cabinets. The separate toilet and bathing area has a new tub with tile shower surround, toiletry niches, all new plumbing fixtures, grab bars, and a sliding glass shower door. Scroll through the photos for a quick tour and to see the before photos of the space.

When Janet LaValle Aurora's client went to work today, this room was empty. He gets to come home to a fully furnished room. We are excited for him to see the grand reveal!

We've included a few behind-the-scene shots as well including the look of relief from our installer when the sofa actually fit through the curved stairwell!


2021 was a busy year for the Signature Design Interiors team! We completed a wide variety of decorating and remodeling projects in the DMV including vacation homes, living rooms, kitchen refreshes, music rooms, dance studios, bedrooms, wine lounges and more! Here's a quick look back!
