“隐身”的设计理念源于一项要求，即挖掘和清除前工业用地西街前的有毒泥土。三个相邻的仓库结构体中的一个被拆除，形成一个单一的工作空间，为移除污染泥土提供地面通道。采用混凝土砌块墙，将东面剩余的两个仓库围起来，并在西面紧贴着新墙建造了一座隐形仓库。部分挖掘区域，在悬垂的新建筑下面被重新分级，形成了一个下沉的花园和会议空间，位于人行道标高以下六英尺处。

原有仓库的北端与新建筑相邻，被设计成承租人奥美的表演和会议区。一扇可移动的钢门将舞台围住，门通向新花园。舞台可容纳150个座位，花园可容纳600个座位，可进行剧场式的演出。将旧仓库与新大楼隔开的新砌块墙有两个主要开口：北面的开口形成了剧院的前厅，里面有滑动的钢门；南面的开口允许车辆通行，车辆在通往场地后部停车场的路上穿过围墙。

新结构体本身有一个三面北端立面和一个四面南端立面。新结构体长100多米，其内外部形状不断变换，有的地方是三角形，有的地方是正方形。这座建筑物预计租给三个租户。奥美租用了一层的剧院，舞台位于旧仓库内，观众座位位于新结构体的大跨度桁架下。在建筑物的南端，有整整两层，在空中升起，可租给一两个租户使用。钢架结构体在南面近似一个平面网格，便于两层租户简单组织空间。建筑中心在一楼有一个玻璃的电梯厅，在二楼和三楼有开放的平台和浴室。平台上涂漆的钢制浴室和相关的机械设备结构体是在现场外预制的，并用起重机吊入到位。访客进入楼层大堂，上电梯进入二楼和三楼的走道，然后向北或向南进入租户空间。北端也是为单个租户设计的，包括二楼和一个夹层，上面的夹层通向下面的二楼。

The design concept for the Stealth originated with a requirement for the excavation and removal of toxic earth on the west street front of the formerly industrial site.One of three contiguous warehouse structures, forming a single working space, was demolished to provide ground access to the area where the polluted soil was to be removed.A concrete block wall was constructed to enclose the two remaining warehouses on the east, and the Stealth was constructed to the west, against the new wall.A portion of the excavated area, underneath the overhanging new structure was re-graded, and landscaped forming a sunken garden and meeting space, six feet below the sidewalk elevation.

The north end of the original warehouse that adjoins the new structure was designed as a performance and meeting area for the tenant, Ogilvy.The stage is enclosed by a movable wall of steel doors which opens to the new garden.The stage can seat 150, the garden,600, for a theatre-in-the-round performance.The new block wall that separates the old warehouses from the new building has two primary openings: the north aperture forms the theater proscenium which holds the sliding steel doors; the south opening admits vehicular traffic, which passes through the wall on the way to a parking area at the rear of the site.

The new structure itself has a three-sided north end elevation, and a four sided south elevation.Over its 100 meter length, the building section transforms, changing its interior and exterior shape continuously as it moves from the triangle end to the square or the square end to the triangle.The building was intended to be divided among three tenants.Ogilvy occupies the ground floor theatre, with the stage positioned in the old warehouse,and the audience seating, outside, under the long span truss portion of the new structure.

There are two full floors, lifted in the air, on the south end of the building, useable by one or two tenants.The steel frame structure approximates a plan grid on the south,facilitating a simple organization of tenant space on the two floors.The building center holds a glazed, elevator lobby on the ground floor, and open decks and bathrooms on floors two and three.The painted steel bathrooms and related mechanical equipment structures on the decks were prefabricated off the site and craned into place.Visitors enter the lobby at grade, and proceed up the elevator to open pedestrian walks on two and three, and then move either north or south into the tenant spaces.The north end, also designed for a single tenant, contains the second floor and a mezzanine above that opens to floor two below.
