The 31-square-meter ground floor holds a master bedroom and bathroom, while the 19-square-meter upper level hosts the kitchen, dining, and living areas. Curved walls rise 7 meters, stacked like bricks and set half a meter below ground for stability, while skylights let natural light pour into every corner.<\/p>\n<p><span id=\"more-236373\"\/><br \/><img decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/02\/27202546\/o-house-japan-3d-printed-reinforced-concrete-home-1.jpg\" alt=\"O House Japan 3D-Printed Reinforced Concrete Home\" width=\"1280\" height=\"853\"\/><br \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/02\/27202605\/o-house-japan-3d-printed-reinforced-concrete-home-4.jpg\" alt=\"O House Japan 3D-Printed Reinforced Concrete Home\" width=\"1280\" height=\"853\"\/><br \/>Kizuki Co. Ltd. and Onocom Co. Ltd. jointly led this project, while COBOD International handled the printing technology. A modified version of their BOD series printers was exactly what they needed to get the job started. Working layer by layer, the printer built the inner and exterior walls, floor slab, roof, and a few inside elements. The printer handled on-site work, however some components were manufactured off-site. To cap it off, the crew installed custom-cut styrofoam for those problematic overhangs and arches that the printer couldn\u2019t handle and increased as the process progressed. Finally, the team gave some of the wall parts a shining polish to get the smooth marble appearance.<\/p>\n<div class=\"aawp\">\n<div class=\"aawp-product aawp-product--horizontal\" data-aawp-product-asin=\"B0D17TMWFB\" data-aawp-product-id=\"218465\" data-aawp-tracking-id=\"tec02e-20\" data-aawp-product-title=\"Bambu Lab A1 3D Printer Support Multi-Color 3D Printing High Speed &amp; Precision Full-Auto Calibration &amp; Active Flow Rate Compensation \u226448 dB Quiet FDM 3D Printers 256 * 256 * 256mm\u00b3 Build Volume\">\n<div class=\"aawp-product__thumb\">\n<p>            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/31iURSU5R7L._SL160_.jpg\" alt=\"Bambu Lab A1 3D Printer, Support Multi-Color 3D Printing, High Speed &amp; Precision, Full-Auto Calibration...\"\/><\/p><\/div>\n<div class=\"aawp-product__content\">\n<p>            Bambu Lab A1 3D Printer, Support Multi-Color 3D Printing, High Speed &amp; Precision, Full-Auto Calibration&#8230;        <\/p>\n<div class=\"aawp-product__description\">\n<ul>\n<li>High-Speed Precision: Experience unparalleled speed and precision with the Bambu Lab A1 3D Printer.

With a firm anchor in the ground thanks to some ground-improvement piles, this hybrid technology enabled the construction to exceed Japan\u2019s stringent seismic regulations, which are among the strictest in the world. All of this demonstrates that in earthquake-prone regions, printed reinforced concrete is a viable alternative to timber framing.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/02\/27203408\/o-house-japan-3d-printed-reinforced-concrete-home-6.jpg\" alt=\"O House Japan 3D-Printed Reinforced Concrete Home\" width=\"1280\" height=\"1280\"\/><br \/>Rounding up a crew of only four in challenging winter conditions made things tough, with freezing temperatures below 10 degrees demanding heated water be added to the mix to keep things flowing, while hot summers of 30 to 35 degrees required careful temperature control to stop the material from setting too fast, but they kept going, working continuously from below ground to the top, and creating multi-purpose walls with an aesthetic finish, structure, and hidden services.<br \/><span>[Source]<\/span><\/p>\n<\/p><\/div>\n<p> O House Becomes Japan\u2019s First Fully Seismic-Approved 3D-Printed Reinforced Concrete Home<br \/>\n<br \/>#House #Japans #Fully #SeismicApproved #3DPrinted #Reinforced #Concrete #Home<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Photo credit: OnocomO House, finished in late 2025 within Kurihara, Miyagi Prefecture, is a 50-square-meter,&#8230;<\/p>\n","protected":false},"author":1,"featured_media":1722,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[763,765,761,704,554,760,764,762],"class_list":["post-1721","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tech","tag-3dprinted","tag-concrete","tag-fully","tag-home","tag-house","tag-japans","tag-reinforced","tag-seismicapproved"],"featured_image_urls":{"full":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home.jpg",960,640,false],"thumbnail":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home-150x150.jpg",150,150,true],"medium":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home-300x200.jpg",300,200,true],"medium_large":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home-768x512.jpg",640,427,true],"large":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home.jpg",640,427,false],"1536x1536":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home.jpg",960,640,false],"2048x2048":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home.jpg",960,640,false],"covernews-featured":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home.jpg",960,640,false],"covernews-medium":["https:\/\/news678.top\/wp-content\/uploads\/2026\/02\/o-house-japan-3d-printed-reinforced-concrete-home-540x340.jpg",540,340,true]},"author_info":{"display_name":"admin","author_link":"https:\/\/news678.top\/?author=1"},"category_info":"<a href=\"https:\/\/news678.top\/?cat=8\" rel=\"category\">Tech<\/a>","tag_info":"Tech","comment_count":"0","_links":{"self":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts\/1721","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1721"}],"version-history":[{"count":0,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts\/1721\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/media\/1722"}],"wp:attachment":[{"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1721"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1721"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1721"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
