The Fitness 1 is a project that plans exercise spaces within an irregularly shaped site located on a slope, including a fitness center, indoor tennis court, and indoor golf practice facility.
The key considerations in this plan include 1) securing an efficient construction area, considering the irregular site boundaries, 2) applying wide column spacing and high ceilings considering the specialized nature of indoor sports spaces, and 3) addressing the complex surroundings of the site surrounded by mountains, schools, and apartments. Keeping these conditions in mind, the focal points of the plan have been outlined.
Various Faces of Buildings
To secure the optimal construction area within the irregular site boundaries, the left facade is segmented into three masses, and the right facade into two. The shape of the left facade, as seen from the school gymnasium, is designed to convey a rhythmic appearance rather than imposing grandiosity.
The front of the right facade, in direct proximity to the building's main entrance, is planned with a glass curtain wall, considering visibility and natural lighting from the road direction. The rear is designed with horizontally elongated windows, allowing the occupants to fully embrace the natural scenery to the north.
The front of the building takes into account the differentiation of each floor's purpose and distinction from the left and right facades.
The ground floor, supported by a piloti structure, opens towards the sports field, providing an open external space. Considering the characteristics of outdoor space users who predominantly sit in chairs, a low wall of the same material as the facade was planned across the front of the ground floor outdoor space.
This allows for the separation of the sightline towards the sports field, ensuring an open and expansive visual experience.
Between the sports stand wall, forming the boundary with the school sports field, and the newly constructed wall at the front of the building, trees have been planted, allowing outgrowth and leaves to extend up to the top of the wall.
This provides additional visual privacy for outdoor space users who primarily sit in chairs, creating a picturesque scene where the sky, nature, and the building naturally harmonize, resembling a wide canvas.
The view of the building from the school in the opposite direction is intentionally designed to harmonize with the existing stand wall.
The second floor houses the fitness center.
In contrast to the majority of users primarily sitting in chairs on the ground floor, the second floor is a space filled with constantly moving individuals as it accommodates the fitness center. However, like the ground floor, there was a need for interference prevention with the adjacent school's line of sight and the creation of an open indoor environment. To overcome these contrasting conditions, a 1.5m high transom window was applied to the front.
Given that people on the first floor predominantly sit, a wall is erected, while for those on the second floor who predominantly stand, low windows have been planned. The third floor is planned for a full-sized indoor tennis court, and considering the facility's characteristics and user convenience, a solid wall is applied to the front.
Rational structure and material planning
The building's structural system is divided into a front and rear based on the central core placement. For the front section, a steel-reinforced concrete (SRC) long-span structure with a maximum span of 14.1m has been implemented, providing a spacious area optimized for various sports activities. In the rear section, where ancillary spaces for the expansive area are arranged, a reinforced concrete (RC) structure has been employed to ensure constructability and cost-effectiveness.
Additionally, considering height constraints due to sunlight restrictions, each floor has been planned with a ceiling height of 5.4m or more, aiming to provide optimal usability. The exterior material features a grey-toned thermal insulation finish to fully reveal the form of the masses. Utilizing rough materials to capture the varied appearances of the facade as they change with shadows, the relatively lightweight properties of the exterior wall material allow for a rational structure plan.
