JN Interior Spaces is a full service interior design firm creating beautifully unique, timeless and award winning spaces for both residential and commercial clients. Always client-centric, Jill Najnigier’s approach has been described as “balancing simplicity with refinement.” Each project exemplifies her passion for design, clean lines and resolute attention to detail. Projects range in breadth and include a historic brownstone on Beacon Hill; a mid-century modern home in vibrant Manhattan Beach; a mountain modern residence in the breathtaking landscape of Wyoming; waterfront homes on Cape Cod, Buzzards Bay, East Hampton and Naples; high-rise condominiums in Boston’s iconic neighborhoods; and inspired commercial spaces. Inspiration for each project is as individual as our client base. It all starts with active listening, observing and engaging. From there, the true needs and desires of each client are revealed and made an integral part of the design process.

“Jill showed her charm and artistry by embracing our family history and memories seamlessly within the design. She is flexible, adaptable and open minded. She has a great understanding of space and worked within our budget and gave us many options. Jill gained our trust by listening carefully and respecting our ideas. We are truly happy that she gave us comfort and beauty everywhere we look. This quote says it all… ‘you can’t buy happiness but you can hire a great interior designer and that’s pretty much the same’ Jill was and will be the perfect choice for our future projects.”
— VG, Osterville

“Jill has played a leading role in 5 big projects for me, both residential and commercial. I’d work with her for her vision alone, because she creates beautiful spaces. But Jill is also one of my favorite people to work with because she combines serious attention to detail with lightheartedness and joy.”

“Jill meticulously executed every detail of our project—from the larger architectural elements in the kitchen and family room, including the design of the built-in cabinetry in basement family room, mudroom and laundry as well the master bathroom to the selection of the perfect lighting fixtures, furniture and artwork to wall coverings, paint colors and cabinet hardware. Through it all, we learned that Jill is not only a talented design professional, she is also great fun. While we love our new digs, I’m a bit sad the project is concluded because we so enjoyed working with Jill.”

“Jill is wonderful to work with. Over 15 years, she has designed 3 residential spaces for me and a commercial space. I have also recommended her to family members who have worked with her on multiple projects as well. In a recent near tear-down renovation, Jill was integral to the architectural design and every material choice. She went on to fully furnish and decorate the space and it is amazing.”

“Jill is AMAZING. For starters she has amazing taste. As important, she listened to what I wanted and I didn’t ever feel like I was forced into her agenda. I have worked with Jill for over 12 years and her ideas always feel ahead of the curve in terms of new trends and color schemes, but at the same time, there is a timeless aspect to her designs. She is super conscientious of my budget and offers suggestions at different price points. She also knows materials and textures and is able to weave different items into an overall plan that would never occur to me. Last, the people that Jill chooses to work with and support her are exceptional. I would recommend without hesitation.”
— Mary, Wyoming

“Jill’s design aesthetic is modern and clean with pops of color that can be changed over time. She is great at staying within budget, provides options and direction but welcomes client input and feedback. Works with dependable and first rate craftsmen who are able to transform plans into perfection.”
— Christine, Boston, MA
