Upscale Landscape Design

I have a private rest house in Riyadh on a 2,500 sqm plot (50m × 50m).
The main building, workers/service building, boundary walls and main structural elements are already built and their locations are fixed. I will provide the complete architectural drawings showing all existing structures.
The main scope of this project is the remaining outdoor space.
I am looking for a creative landscape designer who can transform the available outdoor areas into a unique, high-end private oasis.
I do not want a conventional garden where everything is simply covered with grass and trees. I am open to creative ideas and would like the designer to propose the best use of the space.
The design can creatively combine landscaping, lawn, mature trees, shaded areas, beautiful walkways, outdoor lounges, water features, fire pit, BBQ/outdoor dining, fruit trees, feature lighting, hardscape and other unique outdoor experiences.
The landscape should also create beautiful views from inside the main building, especially through the large glass areas facing the outdoor space.
The style should feel sophisticated, contemporary and natural — similar to a luxury resort or private retreat — while still being practical for Riyadh’s climate.
Most importantly, I want the designer to be creative. I do not want to dictate exactly where every feature should go. I want to see original ideas for how the remaining space can be used, including ideas that I may not have considered.
The goal is to make the outdoor area the main experience of the property, not simply landscaping around the buildings.
