架构师提供的文本描述。一座三层楼高的屋顶扩建了一栋现有的威尔赫·伊米尼时代的房子。这四套新的宽敞公寓-其中一套是一间小木屋-是从一组复杂的几何参考网格中发展出来的，这些网格的形状是由Operngas e和margeretenstra e的不规则的5街交汇处形成的。

Text description provided by the architects. A three story rooftop extension was added to an existing Wilhe lminian-times house. Plans of the four new spacious apartments - one of them a maisonette - were developed from a complex set of geometric reference grids, which were derived from the shape of the irregular 5-street intersection of Operngasse and Margeretenstraße.

在部分中，这些相互冲突的参照系被曲曲折折的三维空间带状合并成一个统一的结构，最终过渡到现有立面的顶部檐上，从而融合了旧的和新的。

In section, these conflicting reference frames were merged into a unified structure by a meandering 3-dimensional ribbon, that eventually transitions into the top cornice of the existing facade, thus merging old and new.

建筑体积、玻璃立面和露台将令人兴奋的景色汇集到维也纳的街道和屋顶景观中，创造了一种慷慨的开放氛围，反映了这一优越位置的城市化条件。

Architectural volume, glass facades and terraces orchestrate exciting views into the streets of Vienna and along its roof scape, creating a generous open atmosphere that reflects the urbanistic conditions of this premium location.
