About Harbour Builders

Harbour Builders has a proven track record for designing, building, and selling unique custom homes in Florida for over 40 years.

In 1976, Spacial Development, Inc. was founded in Gainesville, Florida by David J. Kessler. After many successful projects, Mr. Kessler noticed an increase in property values and demand for quality homes in South Florida and relocated his family to Boca Raton in 1980.

His company designed and built high quality, mid-priced homes, and large communities including residences in Sonoma Lake Estates, Mission Bay, and Hidden Valley in Boca Raton, Barwick Estates in Delray Beach, and The Fountains of Rainbow Lakes in Boynton Beach.

In 1998, Mr. Kessler launched Harbour Builders and began developing upscale, luxury estates including several multi-million dollar homes in prestigious communities such as Royal Palm Yacht & Country Club, The Estates section of East Boca, Highland Beach, Boca Bay Colony, and many more locations.

Harbour Builders has been featured on the front cover of Builder Architect magazine twice in recognition of excellence in the industry and as one of the leading high end home builders in the area. Recent projects range in price from $3 million to over $12 million. They have developed a strong reputation in the community for building high quality homes on time and within budget while providing their customers with personal attention and sharing their decades of knowledge throughout the process.

Client Testimonials

Feedback from satisfied customers that have purchased new homes or completed home renovations in Boca Raton, Lighthouse Point & Highland Beach, Florida.

They Delivered Us a Magnificent Home and We Couldn’t Be More Pleased

When we decided to remodel, others had shared nightmare stories of dealings with general contractors, cost overruns and more. David was a consummate professional throughout the entire process. We came into the project with a vision of exactly what we desired our home to be. David not only delivered on that vision exactly, but also improved the design both architecturally and functionally. David delivered us a magnificent home and we couldn’t be more pleased with the outcome. Derek & Tam Dubner

Superb Quality of Construction with a Focus on Detail.

Over the years Harbour Builders has crafted many new high-end luxury homes for enclaves in the Boca Raton market. What always stands out is the superb quality of construction, the focus on detail, the exceptional melding of materials and design. David Kessler is a master at creating innovative residences and lasting customer relationships. Carmen N. D’Angelo Jr. – Broker | Owner, PREMIER ESTATE PROPERTIES

Professional and On Time. An Excellent Experience.

We used Harbour Builders to renovate our house in order to make room for our growing family. Dave Kessler and his team made our first construction experience an excellent one! Anyone who has hesitations about taking on a building project due to fears of the process or horror stories they heard from others, just hasn’t found the right company to work with. Harbour Builders is that right company… they did the job they said they would, professionally and on time… they made it a great experience! Dan Brauser

Quality Homes with Attention to Detail. No surprises!

Our first home was built by David Kessler in Thornhill Green. We were young newlyweds, inexperienced with the process, and apprehensive about what we were getting into. David was genuine, honest, and a pleasure to work with. He was patient and respectful with us, educated us along the way, and put us at ease. When he made promises, he kept them. There were no surprises at the end. The final walk-through was easy. Even after the closing, he followed through with us to make sure we were happy. After living in our home for about six months, we noticed some things that we wanted changed, and he promptly responded to our request without question or reservation. David pays attention to detail and builds a quality home that he is proud of. We enjoyed living in our “David Kessler home” for years afterwards, and recommend David Kessler and Harbour Builders without hesitation. Andrea & Bob Bogen

A Painless and Enjoyable Experience.

I just wanted to say thank you for the beautiful job you and your company did on our home. You made this a painless and enjoyable experience! You delivered on everything we discussed. The experience and insight you brought to the project were key to its’ success. What I most appreciated was your professionalism, calls always returned, never too busy to answer questions and changes in plans were always accommodated. Your passion for building and pride in what you do shines through in the results. We will gladly recommend you to all friends and family. It was a pleasure working with you, we love our new home! Sean & Anne McCaffery

People Say It's the Most Beautiful House They've Ever Seen. We agree.

My wife and I had been looking for a house for some time in the Lighthouse Pt., Boca Raton, Ft. Lauderdale area. We saw many beautiful homes but few had the formal yet family livability quality that we found in our Harbour Builders spec home in Royal Palm Yacht and Country Club. I knew right away when I walked through the front door that this house was special. We purchased the house immediately even before it was shown at the open house party. That was 2004 and we continue to enjoy it today. I have had many people tell me that our house is the most beautiful house they had ever seen. My wife and I agree. Bob & Tricia Hammel

Exceeded the Level of Customer Service and Satisfaction We Expected.

Harbour Builders worked as the custom builder for our home and I would like to take this opportunity to thank the Harbour Builders “Team” for their hard work and dedication. Harbour Builders exceeded the level of customer service and satisfaction we were expecting. I want to thank you for your willingness to spend the time and energy to meet with us on many different occasions as we worked out the various details on our home. Our experience working with you, your employees and subcontractors was always a positive one. We have been living in our home for over 10 Years now, and I would look forward to working with you and your team again. Joe Carosella – President, RETAIL PROPERTY GROUP
