Luxury Custom Home Builder

At Island Home Designs, we have created a one-stop shop where we transform your Design/Build vision into reality. Founded in Palm Beach in 1997, we have been building custom ocean and intracoastal waterfront homes in Florida now for more than 20 years. Although FL is clearly our home base, our satisfied clients have also asked us to manage unique and challenging projects for them throughout the country.  This bestowed privilege has taken us to NYC, the Thousand Islands Region in Northern NY, the charming ski town of Stowe, VT, the glittering lights of Las Vegas; the beautiful sunsets of Pacific Grove, CA.  All of our projects are built efficiently and expeditiously, including only the best and highest quality of finishes with one goal in mind...exceed our clients' expectations.

Our Services


At Island Home Designs, led by Thomas O'Reilly, we have built projects of every style, including rustic mountain retreats, luxurious ocean and intracoastal homes, charming island bungalows, tenant fit-up of edgy transitional offices, sleek modern estates, cozy traditional homes, authentic Tuscan villas, and even a trendy micro brewery.


What dream can we build for you?

Interior Design

At Living Color Designs, led by Marlene O’Reilly, our in-house Interior Design group coordinates and pulls together the design and final look of our homes. While all of our projects are beautiful, our ultimate goal is always to create a place that our clients will proudly call home.

Real Estate Brokerage

Thomas O'Reilly is also a licensed Real Estate Broker in Florida and New York. With his development experience and intimate understanding of the design/build process, he offers a unique perspective to help match clients with that perfect property. As a buyer's broker, Thomas will represent your interests exclusively. We manage the acquisition and due diligence process and we reward our real estate clients with 30% of IHD's earned commission, to be credited back to you at closing. On large purchases, this credit alone can cover the entire real estate tax bill, during the building process.

What Our Clients Think

"Thank you does not seem enough for all that you have done for me and my family. Being 1,000 miles away normally would make this a torturous process. Knowing you as I do and having as much confidence in you, allowed me to sit back knowing that my interests  were always being taken care of."

Mark F

"It would be hard to find a more complex project than ours...with such a good outcome. Thank you so much!"

Bill D

"Tom and Marlene don’t just build houses, they build homes. They create well designed and constructed spaces that you look forward to spending your time in and around. The entire process from concept, to construction, to completion could not have been easier. If your dream is to build a custom home from scratch, they are the only people to call."
