该设施位于爱荷华州约翰斯顿的一个现有办公室公园内，主要分为两卷：一个私人行政大楼，内有私人办公空间、会议室和休息室，另一个侧翼专门用于补充办公空间和各种支助空间。这两个翅膀是由一个明亮的中庭，作为一个公共大厅和一个共同的循环路径(见下面爆炸的轴测图)。每个机翼都是为了服务于项目内部，同时保持建筑概念作为一个推广装置。

The facility is sited in an existing office park in Johnston, Iowa and is organized into two primary volumes: a private executive wing containing spaces for private office space, board rooms and a break room and the other wing devoted to supplemental office space and various support spaces. These two wings are integrated by a bright atrium serving as a public lobby and a common circulation path (see exploded axonometric diagram below). Each of the wings was developed to serve the program within while maintaining the building concept as a promotional device.

因此，南面的立面(面向州际公路)以突出的建筑防晒板为特色，它不仅作为品牌设备的外壳，而且保护室内办公空间免受太阳热量的增加和眩光。除了作为简单而优雅的建筑的标志性元素，它在减轻室内环境方面也起到了合理的作用。建筑的其余部分都覆盖了一个赤塔式的雨幕，大大缩短了施工时间和安装效率。这个包层系统告知了整个设施所使用的节奏，包括为室内办公空间提供充足采光的全高窗墙，以及对现场的看法。

Accordingly, the southern façade (facing the interstate), features a prominent architectural sun scrim which not only serves as the housing for the branding device but also protects interior office space from solar heat gain and glare.  In addition to serving as the signature element of the simple yet elegant structure, it also serves a legitimate purpose with regards to mitigation of the interior environment.  The remainder of the structure is clad in a terra cotta rainscreen which drastically decreased construction time and efficiency of installation.  This cladding system informed the rhythms utilized throughout the facility, including the full height window walls that provide ample daylighting for the interior office space as well as views of the site.

内部空间设计灵活，以适应公司未来的发展。除了将铰接式办公空间推入结构周边之外，还有一些灵活的开放式办公空间，能够适应德尔塔公司的短期和长期需求。

The interior spaces were designed to be flexible to accommodate future growth for the company.  In addition to articulated office space pushed to the perimeter of the structure, there is also flexible open office space that can adapt to meet the needs of Delta in the short and long term.
