Our work appeals to those who share the passion for excellence, the value of design and the importance of details.

Creators of Exceptional Properties

Our driving passion to extract all the potential a property has to offer with unique finishes, provide us the ability to add a significant value to each property.


The wide array of projects in our portfolio illustrates all the know-how and technical expertise of our architects and designers, who never cease to push back the boundaries of feasibility, bringing into play all the innovation proposed by the worlds of design and civil engineering.


And the finished quality of every one of our properties speaks for itself.

With Rosengart Property Development, you can be assured of a property to be truly proud of.

We know we are.

Real Estate is an Art

The same fundamental beliefs that established the Rosengart name in the world of Art can be found at the heart of our real estate; that beauty is timeless, elegance is never forgotten, and that true quality speaks for itself.

Our Creative Process

We understand the significance that exceptional design has to offer a property with an unrivalled level of distinction and creating value.

We work in close relation with clients to perfectly translate their ideas. Looking at the project, location, budget and style, we suggest a reflective scheme.

Once the style is defined and the photorealistic renderings approved, specific mood boards are developed to discuss colour options and finishing.
