This hot spring project is located in the 3rd and 4th floor of the garden-style resort hotel in Huang-hai Forest Park in Dongtai City. The Huang-hai Forest Park is a 4A grade national park with rich landscape resources in addition to natural hot spring resources. That's why we came up with the concept of "Embrace the forest, breathe nature". We wanted to provide our visitor with the most unique experience: the experience of bathing naked without a swimsuit, hugging the forest and returning to nature. Therefore, we first renovated the building, removing a facades glasses and changing the bathing pool space into a semi-outdoor space, so that customers can embrace the forest without looking through the glass and feel the natural breeze and hear the sound of leaves and rainwater. In order to emphasize the feeling of the forest and greenery, we designed a large frame in the bath pool space to increase the depth of the space and also to capture the natural beauty of the eye. The bath pool is naturally close to the frame, which creates a magical atmosphere that blends with the waterscape. At night, when the lights are turned on, the water waves will be reflected to the top of the frame, sublimating the scene and forming a real forest fantasy hot spring. At the same time, the rest of the space is lightly colored in a Japanese style, which makes people feel relaxed and gives a hint of the natural hot spring experience, but as soon as you enter the pool, the color becomes darker, using the interior design as a backdrop to support the theme of the natural landscape. The designer's intention is to implement the concept of a forest spa at its best.
