It is now a registered site, and the architects aimed to regain the building’s original appearance, and, at the same time, to bring the building up to today’s standards. The roof and wall assemblies were renewed, and measures were taken to renovate the concrete. Windows and doors, as well as most interior surfaces, were replaced. The partition walls have been equipped with new acoustic cladding; in addition, the ceiling soffits were fitted with mineral-wool insulation and acoustic panels. Over the course of time, windows of inferior quality had been substituted for the single-glazed steel windows; new double-glazed windows closely attuned to the original colour and proportions pay homage to their predecessors. The kitchens, bathrooms and dressing rooms have been restored, and remain – though today’s equipment and standards have been integrated – close to the original designs. And Walter Gropius’s apartment was authentically restored.
