Residential Interior Renovation2026

A residential renovation focused on replacing wallpaper and architectural film finishes and reconfiguring the bathroom. The completed bathroom and its design process are documented through hinoki, mosaic tile, glass partitions, and indirect lighting.

Scope of Renovation

Metrocity is an interior renovation that replaces wallpaper and architectural film finishes throughout a residence, with the bathroom as the main area of reconfiguration. Working with the existing spaces, the project defined the extent of changes to finishes, services, and furniture. The entrance and bedroom were examined as separate detailed studies.

The project work was carried out independently within Dongsidae Architecture, with review and approval by principal JUNGGU KIM. Responsibilities included design, drawing production, product and furniture studies, and coordination during construction.

Completed Bathroom

Vertical hinoki grain, small mosaic tiles, and a light-colored floor form the bathroom's material base. A long washbasin faces a timber bathtub, with glass partitions mediating the relationship between the different areas.

Indirect lighting beneath the washbasin and along the upper walls, together with sconces beside the mirror, reveals the materials' texture and depth. The completion photographs focus on the bathroom; the drawings and models that follow document the design and review process.

Design Process

The materials presented cover bathroom finishes, services, and junction details, together with studies of the renovation scope across the residence. Drawings and models of the entrance and bedroom record the proposal stage; completion photographs of those spaces are not included.

Bathroom Design

Hinoki and mosaic tile were selected as the bathroom's primary finishes. The washbasin, bathtub, toilet, and shower areas were organized with material extents and boundaries studied according to the conditions of use in each area.

The key task was to develop finishes, junctions, and ventilation in response to moisture and water use. Alongside the visual application of timber, details address concealed services, connections between materials, and maintenance requirements.

Ventilation and Lighting

The ceiling plan coordinates ventilation units, linear diffusers, and lighting. Equipment and pipework routes were checked, and the drawings include a note to verify whether pipework would obstruct the indirect lighting.

Lighting is arranged around the centerlines of the washbasin, mirror, and bathtub, with sensor and switch controls studied for the low-level indirect lighting. Ventilation and lighting are coordinated with the spatial layout and positions of use.

Junctions and Maintenance Access

Glass partition connections were studied using metal frames and gaskets. Joints requiring disassembly were designed with future removal in mind, and magnetically attached access panels were proposed for access to services.

Boundaries between hinoki and tile, and the ends of metal shelves and frames, were detailed separately. These are construction review drawings; some glass thicknesses and connection conditions are marked as requiring further confirmation.

Washbasin Details

The washbasin combines mosaic finishes, metal components, hinoki members, and indirect lighting. Metal connections were studied with exposed ends, and the drawings specify that corners should be smoothed.

Weatherproof outlets were considered around the washbasin, and the length of the indirect-lighting baffle was adjusted to account for sightlines from the toilet area. The details bring together the furniture's form, use, and service requirements.

Finish Replacement

Wallpaper and architectural film finishes were replaced throughout the residence, with the scope of application to existing doors and furniture defined separately. Construction conditions were studied, including adding a board layer to the substrate to prevent the film from rippling.

Lighting, switches, outlets, and silicone sealant finishes associated with the replacement work were coordinated together. In the kitchen, handle positions and forms were compared for each type of existing cabinetry to define the extent of selective changes.

Entrance

The entrance study aimed to minimize changes to an existing space with some damaged tiles. Selective improvements focused on tile covers, lighting, and an electrical distribution board cover.

The centerlines of existing tiles were compared with the distribution board location to align the lighting and cover. Removal of existing moldings and the thickness and materials of the covers were studied to integrate the added elements with the existing space.

Bedroom Furniture

Two options were studied for combining a bed and headboard, credenza, and pendant lighting. The first pairs simple solid timber furniture with vintage pieces; the second emphasizes the horizontal planes of solid timber furniture.

Ready-made and bespoke pieces were compared, with model images used to review arrangement and visual proportions. The materials shown are options from the furniture proposal stage and do not represent the final installed condition.

Construction Management

The project management drawings distinguish work by space and separate fabrication and procurement items, while identifying matters requiring site discussion and confirmation. They served as a basis for coordinating bathroom construction, furniture fabrication, finish replacement, and product installation.

The project is complete. This page distinguishes the bathroom completion photographs from the design, detail, and proposal materials.
