IWI Interiors. IWI Properties. IWI Hospitality.


Irwin Weiner (ASID, NCIDQ) uses a combination of architectural and decorative elements to create a home as natural and well-proportioned as a finely tailored garment. IWI Properties offers a complete design package, from architectural concept and scope of work to the interior design and landscaping/hardscaping plan.

Designer Irwin Weiner and his IWI team provide architectural detailing, custom furnishings, built-ins, decorating, and landscaping - new or renovated homes and apartments become turnkey lifestyles, reflecting the client's shared vision with our design team. Irwin’s projects range across the globe, from Hawaii to his native South Africa. His work shows up in the Hamptons, Miami Beach, Palm Beach, Orlando, Westchester, Westport, Bucks County, Manhattan, and Long Island. Irwin's clients look for perfection, great value and friendly service for money, and homes that won't date.

Clients hire IWI at the beginning of their new construction or remodeling project to work with architects, landscape designers, contractors, and landscapers. We refine floor plans and elevations, we revise and improve upon electrical and lighting schemes, window details, moldings, and architectural details because we have training both in architecture as well as interior design. IWI makes certain that all aspects of a job fit harmoniously with the client's tastes and lifestyle and the desired functioning for each room. IWI winds up being the client's eyes and ears, supervising the job site to make certain everything is done according to plan. No one likes bad surprises.

  • IWI Interiors originates architectural schemes and finely-layered interiors, either traditional or contemporary, which reflect the clients’ personality and lifestyle. Irwin and his design team always add humor and eclecticism into their comfortable, luxurious homes.

  • At IWI Properties, our team invests in properties and develops them into turnkey real estate offerings, including executive country estates, second-home getaways, and luxury urban apartments. We are pleased to partner with Kurfiss/Sotheby's International Realty to market our properties.

  • IWI Hospitality is our latest undertaking, with the IWI team designing vacation rental villas to a luxury specification in the Orlando, FL market. This project encompasses multi-million dollar high-end hospitality properties as well as premium and mid-range homes that average 14 bedrooms per property, accommodating the global tourist market lodging close to the theme parks for an average stay of eight days.
