For more than 23 years now, Wohnhausbau Büttner Massivhaus GmbH has been in the business of building solid construction turnkey houses at fixed price. With the company building inaugurated in January 2012, the general contractor consistently implemented the corporate philosophy which calls for architecturally appealing and state-of-the-art house construction. In particular, the laying of large-size tiles required a professional approach for the interior finishing. CASA-Bau GmbH of Hummeltal accepted this challenging task and carried it out with the aid of special products and on-site advice provided by PCI Augsburg GmbH. On an area of approx. 850 sq. m, floors and walls were laid with large-size ceramic tiles. The natural stone facing applied in the entrance area and cafeteria proved to be a real eye-catcher.
