A defining characteristic of modern architecture is the elegant, horizontally extending lines. Features such as extended eaves, continuous windows, and flat roofs create a serene yet powerful presence reminiscent of the horizon. By emphasizing the horizontal plane, a sense of stability and expansiveness is simultaneously achieved, culminating in a contemporary aesthetic. The pursuit of horizontality integrated with the structural system forms the foundation of modern architectural design.
Connecting Interior and Exterior with Large Openings.
Expansive glass surfaces integrate the interior with the garden seamlessly. Techniques such as minimizing the visible frame of the sash and connecting windows at the corners create a more open and inviting space. However, selecting glass and sash systems with high thermal insulation performance is a prerequisite for maintaining comfort. Strive to maximize openness while balancing structural safety and aesthetic quality.
Defining Space with the Contrast of White and Black.
In modern design, the contrast of brightness—such as white walls paired with black window frames, and white ceilings contrasted with dark floors—is highly effective. This contrast imparts a sense of tension within the space and clearly delineates the contours of each element. By eliminating intermediate tones, a more contemporary and sharp impression is achieved. The boldness of the color scheme decisively characterizes the modern interior.
Urban Expression with a Flat Roof.
The flat roof is an iconic element of modern architecture. Its simple box-shaped silhouette imparts an urban and sophisticated impression. While thorough waterproofing and drainage planning are prerequisites, there is also the advantage of utilizing the rooftop space. The flat roof creates a contemporary residence that opens up toward the sky.
Creating Expression Through the Combination of Different Materials.
In modern design, combining different materials such as concrete and wood, or glass and steel, generates a rich expression. By clearly defining the boundaries between materials and accentuating their individual characteristics, the contrast between materials adds depth to the space. The selection of materials and the method of combining them determine the quality of the design.
Creating Fluid Spaces with an Open Plan.
Rather than dividing the space with numerous walls, creating a large, open-plan room allows light and air to flow freely throughout the residence. The living, dining, and kitchen areas are visually connected, enabling occupants to remain aware of family presence while engaging in different activities. Flexibility is maintained by gently partitioning the space as needed using movable partitions or furniture.
Integrating Lighting into Architecture.
In modern spaces, lighting fixtures are designed to avoid asserting themselves as distinct objects. Through lighting strategies integrated with the architecture—such as downlights, indirect lighting, and linear lighting—the design focuses on the light itself. Maintaining a flat ceiling plane enhances the abstraction of the space. The seamless integration of lighting critically determines the refinement of modern design.
Composed of Geometric Forms.
Modern architecture is composed of clear geometric forms. The volumetric composition combining rectangular and cubic shapes, as well as the use of pure forms such as circles and triangles, brings order and beauty to the architecture. Avoiding complex shapes and structuring spaces with simple geometry is a fundamental principle of modern design.
Lightness Achieved Through Cantilevers.
By employing cantilevered structures for balconies, eaves, and staircases, a sense of suspension and lightness is created. Although this requires advanced structural calculations, the visual impact is significant, producing an expression characteristic of modern architecture. This is the essence of modern design, where structural beauty and aesthetic appeal converge.
Controlling Light and Airflow through the Courtyard.
Even in densely built urban sites with challenging conditions, incorporating a courtyard allows for the introduction of natural light and ventilation. A design that is closed to the exterior yet open to the interior achieves a balance between privacy and an expansive living environment. The circulation path centered around the courtyard also enriches the spatial experience in a modern residence.
Integration with the Space through Custom-Made Furniture.
Custom-made furniture, designed integrally with the architecture rather than using commercially available pieces, completes the modern space. Counters and shelves constructed to flow continuously from the walls are perceived as part of the architecture, enhancing the spatial unity. Blurring the boundaries between furniture and architecture is a hallmark of modern design.
The Aesthetics of Exposed Structure.
By exposing structural elements such as steel columns and beams, as well as concrete frameworks, a modern sense of robustness is achieved. The structure itself becomes a design feature, and the beauty born from necessity dominates the space. The coexistence of structure and design enables the realization of modern architecture.
Dimensions of Slope, Tread, and Riser.
The ease of ascending and descending stairs is determined by the slope. According to the Building Standards Act, residential stairs must have risers of 23 cm or less and treads of 15 cm or more. However, for comfort, risers of approximately 18 to 20 cm and treads of about 20 to 22 cm are generally preferred. A balance where "(riser × 2) + tread ≈ 60 cm" is considered optimal for comfortable stair usage.
Selection of Staircase Configuration
Straight staircases are simple and space-efficient; however, they lack landings, which increases the risk of falls. U-shaped and L-shaped staircases include landings, enhancing safety, while spiral staircases serve as spatial focal points. The choice of configuration should be made comprehensively, considering site conditions, budget, safety, and design aesthetics.
Installation and Height of Handrails.
Handrails are a critical element in ensuring the safety of staircases. Installing them on both sides, rather than just one, enhances safety. The standard height is approximately 75 to 85 cm from the floor surface, but it can be adjusted according to the user's height. The design of the handrail also influences the overall impression of the staircase, so it is important to select a solution that balances both functionality and aesthetics.
Lighting Design and Footing Safety.
Staircases are areas with a high risk of falls, making adequate illumination essential. A lighting plan that effectively highlights each step edge—such as footlights illuminating the edges of each tread or indirect lighting installed on walls—creates shadows while clearly defining the risers. Incorporating motion sensors further enhances safety during nighttime use.
Presence or Absence of Risers
Skeleton stairs without risers create an open and airy impression by allowing sightlines to pass through. When combined with a double-height space, this design enhances the sense of spatial expansiveness. Conversely, stairs with risers provide a sense of security and reduce the risk of objects falling through. For households with small children or pets, stairs equipped with risers offer greater safety.
Stair Placement and Circulation Flow.
The placement of stairs determines the overall circulation flow of the house. Positioning stairs in the entrance hall allows direct access to the private rooms on the second floor, while opting for a living room staircase creates a layout where family members can easily see each other. Each option has its advantages and disadvantages, so it is important to choose according to the family’s lifestyle.
Material Selection and Texture.
The materials used for stair treads, risers, and handrails greatly influence the ambiance of the space. Wood imparts warmth, while steel conveys a sharp and modern aesthetic. When selecting materials, consider slip resistance and durability, ensuring harmony with the overall interior design.
Utilization of Under-Stair Space
The space beneath stairs can be utilized for various purposes such as storage, a restroom, or a study nook. Due to its irregular shape, custom-built shelving is an efficient solution. However, in the case of an open staircase in the living area, keeping the under-stair space open enhances the sense of spaciousness within the room. It is important to plan with a balanced consideration of both function and design.
Relationship with the Atrium
By positioning the staircase adjacent to the atrium, a sense of visual expansiveness and enhanced natural light can be achieved. This arrangement allows occupants to overlook the lower floor from the upper level and to experience the spatial entirety while ascending the stairs. However, it is important to comprehensively consider the potential impacts on acoustics and thermal comfort.
Designing Landings.
When a straight staircase has many steps, incorporating a landing midway enhances safety. Landings also serve as resting areas and reduce the risk of injury in the event of a fall. Installing windows in the landing ensures adequate natural lighting and ventilation.
Design Appeal and Spatial Accents.
Staircases serve not only as functional elements but also as spatial accents. By highlighting the natural beauty of wood grain or meticulously designing the handrails, they can assert a commanding presence as focal points within the interior.
Consideration for Future Safety.
Staircases require careful design to ensure safe use during advanced age. This includes implementing gentle slopes, installing structural supports to accommodate handrails on both sides, and providing adequate lighting. Such measures contribute to staircases that can be used safely and comfortably over the long term. Additionally, reserving space for the potential future installation of a home elevator is a viable option.
