We are over the moon with the staging Design Alchemy did for us. We were honestly expecting a quote about half of what we paid, but after seeing everything Deborah and her team brought in, well, we couldn't be happier. Great detail, furniture is in excellent condition, and put together so professionally. So pleased!

Deborah was the lead designer on a luxury investment project of mine. I simply told her to do whatever she wanted within my budget to make my project a success. She delivered astounding results and I can't speak highly enough about her. Deborah and her team took my project from a dream to a reality. I gave them a budget and they performed beyond my expectations. I was impressed with their ability to handle all aspects of my luxury investment from remodel, staging and finally the transaction. Over
asking price!! They were amazing and I can't wait till the next project.

Without hesitation I highly recommend Debra Costa to anyone seeking professional interior and exterior design assistance. Her vast expertise and intuitive eye for color and design far exceeded our expectations. We strongly feel we were able to sell both our homes in a day because of how well she staged it for us, both inside and out. Her color choices went beyond the normal interior/exterior color palettes. The color tones, furniture placement, and accessories were inviting, complimentary, and made our home standout above the competition. Debra is truly an expert in her field.

I've worked with Deborah in a variety of capacities over the last decade and have always been extremely pleased with the results. She has helped with the design/build of new construction, remodel layout and finish selection, interior design, exterior landscape, furniture selection and placement, and new home design for eight different properties as well as office layout/design for my corporate headquarters. Not only is Deborah organized, efficient, and budget conscious but she makes the process pleasurable. I couldn't speak more highly of her talent.

I've known Deborah and her work for years and cannot speak highly enough of her dedication, work ethic and creativity. Deborah quickly envisions and cost effectively implements her ideas with incredible resourcefulness and ingenuity. I never hesitate to contact her for any of my projects or just a quick bit of wisdom. Her style and flair for every detail never ceases to amaze me. The results she has created in flip projects, my personal residences and other projects I've experienced is superior and lovely to witness. I highly recommend the Design Alchemy team for any project...there's no job Deborah can't handle.

Deborah Costa is amazing. I have worked with many high end designers over my years in construction and real estate and I have never had the privilege of working with someone quite like her. She is a true design professional. Incredibly talented and creative, she also has a thorough working knowledge of construction and space planning. We have worked through several major reconstruction projects together and she always delivers beyond our clients’ expectations. She excels at designing livable floor plans, productive work environments, comfortable and inviting surroundings for fine living and entertaining. Deborah has an absolute gift for bringing all the design components together into a cohesive, refined and finished product. She is personable, proficient, and a real pleasure to work with. Deborah has my highest, most sincere and confident recommendation.

We hired Deborah to stage a home that we needed to sell, and later, to build a custom home.
She took just a weekend to stage our home! Within a week of her staging job, we had a great offer. She is extremely talented, competent, and budget-conscious.
We then hired her to assist us in building a custom home from scratch. She was with us every step of the way. We were blown away with how efficient and cost-effective it was to hire her. Not only is she an amazing and brilliant designer, she also is extremely knowledgeable about the building process and the real estate market. She had an almost innate ability to tell if we would like something or not, and she helped in more ways than I can even list.
We have been living in our new home for over 5 years now, and we couldn't be happier. We often talk about what a blessing it was to find her, and how much money we must have saved by having her involved from the very beginning of the process.
In addition to all of this, she is a wonderful person with unmatched integrity. You will not be sorry you hired Deborah.
