近年来，随着城市密度的增加，新型混合高层建筑不断涌现，“拉链”大楼则是新一代混合高层建筑的代表。项目坐落于杜塞尔多夫Dominikus-Krankenhaus医院的前公园场地上，综合了各类医疗实践以及居住功能。综合保健衍生出的协同效应使现有医院具备了跨区域性的重要意义，同时也为“未来医院”提供了一个优秀的范本。

In recent years, increasing urban density has led to new kinds of hybrid high rises. Our project ZIPPER is part of the latest generation of these mixed-use concepts. The project combines various medical practices and residences on the former park grounds of Dominikus-Krankenhaus in Düsseldorf-Heerdt. The synergy effects thus achieved with comprehensive health grant the existing hospital transregional importance as the “prototype of a hospital for the future.”▼下部楼层为医院，上部塔楼为住宅，the lower floors are hospital and the upper tower is residence
莱茵河畔，杜塞尔多夫市Dominikus-Krankenhaus医院的原公园场地上，一座集居住与医疗设施于一体的新型综合体正在崛起。从远处便清晰可鉴的混合高层建筑ZIPPER大楼，成为该医院转型的醒目地标。J.MAYER.H事务所在该医疗住宅综合体国际设计竞赛中拔得头筹，继而操刀该混合高层建筑的设计与建造。

Right on the Rhine, a new campus combining housing and health facilities is being erected on the former park on the grounds of Dominikus-Krankenhaus, a hospital in Dusseldorf-Heerdt. The hybrid high-rise Zipper is the striking emblem of this transformation, visible from afar. J.MAYER.H was the winner of the international design competition for this joint residential and health unit.

莱茵河和杜塞尔多夫的广阔全景成为这栋大楼得天独厚的优势。穿孔金属幕墙立面的设计，为建筑内部灵活布置开放和封闭区域提供了条件，同时创造出柔和自然的空间氛围。在东、南、西三面，波浪形态的建筑外壳向周边环境打开，同时也起到了必要的遮阳与抗风作用。而建筑北侧则采取了更为封闭的立面形式，以隔绝来往车辆产生的交通噪音。整栋大楼就如同“拉链”（ZIPPER）一般，在开放和封闭之间循序渐进，并为医院留出了充足的发展空间，使其能够灵活回应未来发展的需求。

The unique panorama view over the Rhine and Dusseldorf makes the building striking. The conception of the perforated metal curtain façade allows for a gentle arrangement of open and closed areas. On the east, south, and west sides of the building, the wavy shell opens generously while also offering shade and wind protection. On the north side, the façade is closed to provide sound insulation from the traffic. Like a zipper, the transitions between open and closed are gradual and allow for flexible adaptation during the process of development over the years.

建筑较低的六个楼层中综合了集体会诊、专家以及理疗空间，与现有的医院形成了良好的协同作用，为当地创造出一处高水准的医疗保健中心。建筑上部14层则混合了各种形式的住宅，并为居住者提供了宽敞通透、充满自然采光的舒适生活空间，以及大量露台、阳台、凉廊和屋顶花园。

The combination of group practices, specialists, and therapists in the lower six floors of the building offers synergies with the existing hospital to create a medical health center with an importance that goes beyond the local region.
The fourteen floors above feature a vital mix of various residential forms resulting in transparent, light-flooded living spaces with generous terraces, balconies, loggias, and rooftop gardens.
