[Construction Example 08] The exterior walls of the city hall are recreated with decorative exterior materials featuring a distinctive granite-like design.
The exterior walls of the expanded city hall were finished with a similar texture to the old city hall, using "Dotland" with a chiseled finish in granite.
We would like to introduce an example of the exterior wall of the newly constructed annex of the city hall, finished with "Dotland High-Rise Stone," which has a chiseled finish resembling granite. 【Project】[New Construction] Annex of the City Hall in Higashiomi City (Shiga Prefecture, Higashiomi City) ◇Construction Date: February 2014 ◇Construction Area: 1,200m2 ◇Substrate: RC 【Client's Challenges and Requests】 ◆The exterior wall of the annex should have a stone-like finish with colors and textures similar to the existing main building's column-type artificial stone finish. ◆To reduce maintenance costs for the building's exterior, we want to use long-lasting exterior materials. 【Selection Process】 ◇Seismic retrofitting work was carried out on the adjacent "Old Yokaichi City Hall," which is a building selected as one of the "100 Best Japanese Buildings," so it was necessary to preserve the existing design. ◇The new annex being constructed was also required to match the exterior design of the old city hall, and samples were created and proposed accordingly. 【Selection Points】 ◆It reproduces the texture and feel of high-quality granite with a thickness (approximately 6mm to 10mm) and impressive relief that cannot be expressed with conventional coatings. ◆It is lighter compared to stone materials of the same thickness, reducing the burden on the building's structure. ◆This product excels in durability, weather resistance, and stain resistance, maintaining a beautiful wall surface for an extended period.
