It’s a pleasure to work with David Nadolney of Open Concept Designs, Honolulu, HI, because of the qualities that define him, including:

Integrity – David is a principled man who is trustworthy, honest, sincere, candid and straightforward.

Design/architectural expertise – He understands your vision and provides the best design possibilities. Renovations in a high rise building can present many challenges, but David’s expertise provided a suitable and acceptable outcome.

Patience – David is a very patient and understanding person. He takes the time and effort to accompany you to the various suppliers that provide the items required for the project. With his design expertise, he is adept in suggesting several choices with regard to style, color, etc. It becomes a joint effort with mutual agreement in the final selections. By being involved in this joint effort, it provides you, the client, with personal pride and satisfaction when the project has been completed.

Caring and professionalism – He is like a trusted friend who makes sure that ongoing projects conducted by the contractor are progressing in a satisfactory manner and making sure that you, the client, are happy.

Thanks to David, I have one of the most beautiful and functional expanded kitchens in my condo building. My master and guest bathrooms have been transformed into elegant spa-like retreats.

Without hesitation, I would recommend David to anyone planning to renovate a home or apartment, or to construct a new home. You will not be disappointed.


Fantastic taste

Mr. Nadolney’s keen eye for design and attention to detail drew us in. There is nothing quite like a David Nadolney kitchen. He has the unique ability to combine great taste and style with common sense design. My chef husband immediately fell for his new work space.

Although the design and detail of Mr. Nadolney's construction drew us to his property, the home inspector’s report convinced my husband and I this was the place to buy. David Nadolney builds sound, energy-efficient homes.

As a Realtor, I am attentive to construction that is both attractive and energy conserving. Several year’s after it’s purchase, I had an energy audit performed on our home and it passed with flying colors.

I highly recommend David Nadolney to design and oversee construction or remodel of your home. Whether contemporary or traditional design, David possesses the experience, keen eye, sensibility and good nature to make your new build or remodel experience both pleasant and successful. I would work with David Nadolney again without hesitation.

Our bathroom remodel project manager/design consultant David Nadolney was fantastic! He incorporated all our thoughts into the project and had super recommendations on materials, custom cabinets, and fixtures. He consistently let us know about progress and kept the work in our price range. The project proceeded in a timely fashion and his quality control of sub-contractors gave us a lot of confidence. David designed a beautiful walk-in shower that exceeded our expectations! We love our new bathroom! His extensive experience and expertise were obvious and made us very comfortable trusting him to deliver a superior product. He gets our total recommendation for your kitchen, bath, and other remodeling projects.

Remarkable attention to detail

I have personally know David Nadolney since early 2000. I have also known David as a Builder, local business man and even an accomplished Chef. David was a prominent builder in the Heights when I first met him and was building expensive home in the Houston Heights long before it was fashionable. His work was interesting to me because his attention to detail is intense and his mill work remarkable.

The first house that I visited was on Cortlandt, a coveted street even then and was exceptional in the sense that each room had his finishing touch that I had rarely seen with other builders a nice home and WOW property. David’s properties were always WOW homes.

In addition to the quality of the construction, David has a keen sense of design. He understands how a home should function but with a flair that makes it interesting. His creative edge always makes for an exceptional structure but his flare for cooking, which I discovered year later, explains why I loved his kitchens so much.

If you are considering David Nadolney to help you with new construction of even renovation I would strongly recommend him.

We are impressed!


I’m incredibly impressed with your design of my custom kitchen and baths!

I just received approval from the HOA today, and can’t wait to get started. Thank you for all of your help with the HOA and getting the permit from the city.

Excellent workmanship

Chelsea and David,

It has been such a pleasure to work with your company. From the beginning of the process we felt that you both took a personal interest in our project and our family’s needs. We had no idea how much was involved to accomplish our dream renovation. We met with several salesmen from various builders, but none of them were able to come up with the creative solutions that you did. We can hardly express how much time that we saved obtaining several estimates on your blueprints. The ease of communication between your team of contractors and the quality of workmanship exceeded all of our expectations. We will definitely refer you to our friends who need work in the future!

We are thrilled with our final plans

We interviewed several design build companies before deciding who was a good fit for designing our new-multi generational home. We had a long wish list of things we wanted in our design.  Then we met David for the first time at the last BIA show in January. He listened to our needs and understand our budget. David expanded on our ideas and created an awesome floor plan and exterior design. We are THRILLED with our final plans and anxiously awaiting our permit to start construction.

Saving my family’s home


Saving my family's home was an obvious decision for my husband and I after my grandma passed away. Not only were we saving it from foreclosure, but we were saving this 1950's, termite eaten, molded plantation home that only Wahiawa weather can bring. 

What do first-time home owners do?

Call David Nadolney of Open Concept Designs. He brought our vision to life, while keeping the warmth of our original plantation home that would make my grandma feel proud. 

Who knew that table legs and lighting could bring to life our kitchen island? He turned our small, rotted out kitchen that could only fit 2-3 people at a time into our family's new hang out. His design made it possible for my parents to finally cook together and our family of 10 to eat together with ease. 

David's design changed our life and were grateful. 

One can't argue that in order to do this, you need an amazing team. His design is his reputation, therefore they must be reliable, hard-working, and ethical. We got just that with Howard Kunimura, one of the contractors whom David works with to materialize his designs. 

Renovation can be stressful, and costly. Something my husband and I have nothing to compare this experience to as first time home owners.  I've been told by many in the business that we had one of the smoothest renovations. This is because of David and his team. There are no words to describe how filled our hearts are with gratitude. 


The Kitchen is the Heart of the Home! 

The Kitchen is the Heart of the Home! 

Our previous 1st floor was so chopped up, and we had a very small kitchen.

Open Concept Designs re-designed our entire First Floor, added additional footage in our backyard,

moved our laundry room, took out several walls, and created an awesome Family Gathering area.

Everyone loves our home. We never imagined it could be so wonderful. Thank you so much David and Howard.

Stunning work

Aloha David,

I wanted to give a big thanks for the professionalism of your team. Lisa at Constantino was consistently wonderful during all three of our meetings and the contractor who did the installation of our Dekton was also phenomenal - friendly but professional. Our master bath is ABSOLUTELY STUNNING! Your company has an exceptional team of good people who are wonderful ambassadors for your business.

I highly recommend David and Open Concept Designs

My 50+ year old kitchen and bathrooms were in desperate need of an update. 

David took my rough ideas for a remodel and turned them into spectacular new areas.            His attentiveness to detail and reasonable price point of his General Contractor sets him apart from others.  His extensive home building experience was clearly evident when he recommended critical modifications required for structural design and integrity.  I can’t be happier with my new kitchen and bathrooms.  I highly recommend David and Open Concept Designs for your remodel.

To Whom It May Concern

I am writing to provide our testimony regarding our experience with David Nadolney and his company, Open Concept Designs, over the past two and a half years.

Prior to engaging the services of David my wife and I had three prior architects that we engaged in designing a new home in Hawaii Kai.  Our experience was very frustrating and disappointing as we spent several thousand dollars and went through many plans and revisions before terminating their services.  Much of the problem was that we felt the architects were more interested in advocating their ideas and concepts than taking into consideration what we wanted and were comfortable with. Each architect had different ideas and perspectives of what they thought would meet our needs but did not seem to consider what fit in our lifestyle and likes.

We were fortunate to meet David at the BIA Home Show and were attracted to his low-key approach in discussing our situation and prior experiences with the other architects.  He offered to meet with us at our home to get a better understanding of the “lay of the land” and to discuss what we wanted in a new home design.  We were impressed with David’s patience and understanding of our situation and was able to address our issues.  He was open about his recommendations and provided sound reasons for them.  There were some conflicting ideas, but David never tried to impose his ideas or concepts on us.  Instead, he always tried to accommodate our wishes into his designs and offered several different approaches to making out wants work to make the house more flowing and cohesive.

It has been a pleasure to work with David and to hear his ideas and recommendations whenever we have a new “idea” that we wanted to incorporate in the house plans. He does not discourage our input but does point out issues and problems that make our ideas would cause or affect the design of the house.  He has been open to new ideas and is able to make recommendations to ensure that our ideas are practical and affordable.

In short, we are pleased with our relationship with David and are more than satisfied with the quality of his work and his dedication to meeting our needs in designing our new home.
