Cutting Primary Structural Beams for Hanok-Style Cafe
The team is precisely measuring and cutting Douglas fir beams to the specific dimensions required for the traditional Hanok-style cafe interior. Kim Ji-hoon is carefully reviewing the architectural drawings that show the traditional proportional relationships between beam elements, ensuring all cuts follow the sacred proportional system of Korean traditional architecture. As they work, they're marking each beam with chalk according to the cutting plan before proceeding with cuts. Choi is operating the compound miter saw for angled cuts required for beam ends that will be visible in the finished design, while Song assists by holding the longer beams steady and applying a pencil mark at measured points. They're taking extra care with these cuts as the beams will remain exposed as decorative elements, requiring precision within 1mm tolerance. For each beam, they're cutting a primary length first, then adding any specialized end treatments or notches needed for traditional joinery connections. As each beam is completed, it's carefully moved to a staging area where it's labeled with its position code according to the installation drawings.
Precision Joinery Work Combining Traditional Hanok Techniques with Modern Fastening
The workers are engaged in specialized joinery work that merges traditional Korean Hanok woodworking methods with contemporary construction techniques. Kim Ji-hoon is supervising as Choi Seo-yeon and Song Min-jae prepare and execute various joint types including mortise and tenon, lap joints, and scarf joints. They're carefully measuring, marking, and cutting connection points on the structural beams that were previously dimensioned. The team is using hand tools for initial joinery work—chisels to create mortises, hand saws for precise cuts, and Japanese pull saws for flush cutting tenons—while supplementing with modern fastening hardware. They're concealing metal brackets behind decorative wooden elements and using specialized black finishing screws that will remain visible as design features. Each joint is dry-fitted before final assembly to ensure proper alignment, with special attention to maintaining traditional proportional ratios important in Hanok architecture. For structural integrity, hidden reinforcement plates are being installed at critical junctions where beams meet at angles, ensuring the structure meets modern building codes while preserving traditional aesthetics.
Erecting Scaffolding and Assembling Ceiling Joist Framework
The team is working on installing the ceiling framework that will be a key visual element of the traditional Hanok-style cafe. This task involves first setting up mobile scaffolding platforms to safely reach the ceiling height of approximately 3.5 meters. The team must then carefully measure and mark ceiling attachment points according to the architectural plans which specify traditional Hanok proportions. The ceiling joists are being installed in a grid pattern with primary support beams running the length of the space at 1.2-meter intervals and secondary cross-members at 0.6-meter spacing. Each joist connection requires precise cutting for decorative joinery that will remain visible in the finished space. The carpenters are using a combination of traditional mortise and tenon joints reinforced with modern black finishing screws that will become design elements themselves. The team must constantly check for level and square using laser levels and traditional measuring techniques, ensuring the entire ceiling framework maintains the precise geometric alignment crucial to authentic Hanok aesthetics while accommodating modern electrical and ventilation requirements being installed by other trades.
Installing Vertical Wall Frame Elements with Decorative Features and Utility Connection Points
The team is installing pre-cut traditional Korean Hanok-style vertical wall frame elements that will remain exposed as decorative features in the finished cafe. These frames must be perfectly plumb and aligned with the previously installed ceiling joist framework. Each frame includes specially notched sections where electrical conduits and plumbing lines will pass through while maintaining aesthetic integrity. Kim Ji-hoon is supervising the positioning of frames using a laser level, while Choi Seo-yeon handles the precision fitting of joinery connections and decorative elements. Song Min-jae is assisting with material handling and fastening using impact drivers with black finishing screws. The team is taking extra care to ensure the traditional wooden elements maintain their visual appeal while accommodating modern utility requirements. Each frame must be secured to both the floor and ceiling structure with specific attention to maintaining traditional proportions and geometric patterns characteristic of Hanok architecture.
Securing Visible Connections with Black Finishing Screws
The carpentry team is meticulously securing all visible connections in the Hanok-style cafe interior frame using impact drivers with specified black finishing screws. This task requires precision and attention to detail as these connections will remain visible as decorative elements. The carpenters are carefully countersinking each screw to a uniform depth, ensuring proper alignment with the wood grain, and maintaining consistent spacing between screws. They're following traditional Hanok aesthetics while incorporating modern fastening techniques. Each connection point is being pre-drilled with pilot holes to prevent wood splitting, particularly important in the hardwood joinery. The team is working systematically from the ceiling down to the walls, checking each connection for both structural integrity and visual appeal before proceeding to the next area.
Clean and finish exposed wooden elements according to client specifications
The team is now focusing on the final aesthetic preparation of all exposed wooden frame elements in the traditional Hanok cafe interior. This critical task involves thoroughly cleaning each visible beam, joist, and frame member to remove construction dust, fingerprints, and any adhesive residue. After cleaning, they apply a specialized natural oil finish that highlights the wood grain while providing protection. The client (Seoul Brew Company) has specified a medium-amber tone that resembles aged pine traditionally used in Hanok construction. The application process requires multiple thin coats with adequate drying time between applications. The team is meticulously working on each exposed beam, ensuring consistent color and sheen throughout the space. Special attention is given to corner joints and decorative elements where the finish must penetrate evenly. The work requires careful hand application to avoid drips or streaks that would be highly visible in the finished space.
Final Inspection of All Visible Frame Elements
