I have work with KOS Building Group for over 10 years as a professional and would recommend Bob Ben-Simon and his team in providing excellence in all of the projects they have developed. KOS Building Group is focused on the details and development to create a successful project from start to finish and have always been an absolute pleasure to work with.

I marketed one of KOS Group's fine properties. Actually Bobby did an extensive renovation and addition, thoroughly new systems, windows, drainage/ landscaping/ waterproofing. The quality was beyond expectation. The house sold before it formally went on the market, the new buyer recognized the value of fine quality and superior building. I would recommend KOS Group to anyone looking to buy or upgrade a house.

We built our home with KOS Building group and really appreciated how they tried to accomodate our every need and understand our ideas and expectations. We had fun during the process as they explained in detail what was to be expected regarding timing and the selection of the materials. They recommended a very wide array of choices and took care of the difficult part of ordering right sizes, and specifications directly with the company to avoid mistakes.
It was a very pleasurable process as the team is really knowledgeable and really enjoy what they do. I really recommend to work with them.

We purchased a home built by KOS. The quality of materials used, solid construction, appearance, attention to detail and their ability to meet deadlines were all superior and more then met expectations. In addition, their expertise, professionalism and responsiveness well exceeded my already high expectations, especially post-closing. Prior to the purchase we asked for some changes to the configuration of the house, such as adding rooms, reconfiguring some rooms, changing placements of doors, and other cosmetic changes. KOS completed the work on time, and the workmanship was excellent. Post closing, KOS has done an excellent job on follow-up items that invariably arise with a new house. KOS has been very responsive to our needs, correcting problems usually by the next day. The entire team I have dealt with at KOS is extremely professional and I would highly recommend them for any project big or small.

I have seen many of the custom built homes.
They are just exquisite, the beauty and elegance.
Much attention is paid to the smallest detail
in wood work, painting and overall design.
I can highly recommend this company.

I've purchased my house (over $3 mil) from KOS Building Group 10 years ago and it feels like new. Even though my warranty expired, I can always count on this company to help me out with good advise. I love my house!

I had the privilege of purchasing a home from KOS Building Group. The
top-notch quality throughout the home is impressive and the fine
detail work is exceptional.
The owner, Bobby Ben-Simon, was professional, courteous and extremely
knowledgable. He also had creative ideas as to how to maximize our
living spaces. It was a pleasure working with KOS Building Group.

I am a real estate broker who sold a $3,000,000++ home in Scarsdale, NY built by KOS Building Group. The house is now 3 years old and looks as good as it did when I sold it to my clients. There was very little settling and the builder has been responsive to inquiries from my buyers.

I have worked with KOS from time to time as a residential real estate agent with Sotheby's. Mr.Ben-Simon has decades of experience as a high-end builder who constructs quality homes. He works with good architects and has a good feel for what the Greenwich market is looking for.
