Grand Hyatt Istanbul Hotel, "34" + Gaia Fitness Center / Spa

Istanbul, Turkey

27,000 square feet

The Mansion at Grand Hyatt Istanbul is an innovative venue that provides an all-inclusive 5-star service for business and social events, featuring meeting spaces that are more intimate, modern and residential than that of typical boardrooms and event spaces. The 4,500 square foot Mansion offers four different sophisticated environments or "residences," that are paired with the exceptional and personalized service of Grand Hyatt. Each residence has a living room and a dining area with luxurious finishes combined with built-in state-of-the-art conferencing equipment necessary for business meetings.


"34" is a place of casual dining located within the Grand Hyatt Istanbul, featuring five show kitchens showcasing the preparation of pan-Mediterranean cuisines: the cold mezze kitchen, the pasta kitchen, the bakery, the wood fire kitchen and the pastry kitchen. A challenge of this project was to create five unique dining experiences while presenting a cohesive and open design. The eatery is designed to incorporate the historic and exotic elements of Istanbul with the contemporary and luxurious Grand Hyatt.


The Gaia Fitness Center and Spa at Grand Hyatt Istanbul features a luxury spa, an exercise facility a steam room and a traditional Turkish bath. Each of the treatment rooms in the spa is designed with custom color-therapy lighting as well as a private shower. The Turkish bath, with white marble tiling and a high ceiling, recreates the traditional hammam, but with a modern aesthetic.
