办公室的大部分空间采用开放式布局，只有不足一成员工拥有专属的私人办公室。这样的设计容许通透开阔的视野，同事之间也能保持必要的联系。私人办公室和会议室等以实体墙间隔起来的部分被安排到远离窗户的位置，因此窗外景色不受遮挡，室内又能获得自然采光。员工可按需要到办公室内适合的地方工作：要进行大型讨论或汇报，可预约使用会议室和小组工作室；若追求灵活弹性的空间，便可选择常规工作间旁边的开放空间、靠窗的共享工作台或茶水间。此外，办公室里设有不少小型房间，员工可在这里进行私人电话会谈或一对一的会议。

Sasaki深信创作原型设计能促进改变。以BPS在市政厅709室的临时办公室为例，它充分展现当代工作环境应有的条件，员工更能借此机会表达他们对设计的意见，从而帮助BPS在布鲁斯·博林市政大楼的新址实现更臻完善的效果。BPS临时办公室拥有32个长2.5米、宽2米的工作站、2间电话会谈室、1间会议室及2个开放式协作空间，而私人独立办公室只有2间。工作站的组合方式非常多样化，并且沿办公室四周的窗户布置，为员工带来一览无遗的市中心景色。为配合天花的网格结构，项目选用了长形灯具，柔和的照明效果为室内环境倍添气氛，市政厅的混凝土天花也更显个性。

由Sasaki进行室内设计的市政厅709室已成为大楼的永久空间，目前由波士顿市环境部门使用。

Creating prototypes is one of our many strategies for facilitating change. For the BPS, we were able to take over Room 709 in City Hall to demonstrate the principles of today’s workplace and to gain feedback from city employees, which would then be used in the design of the furnishings at the Bruce C. Bolling Building. Thirty-two open, 6×8-foot workstations are configured in a variety of ways, and arranged at the perimeter of the room with views of downtown. There are two phone rooms, one conference room, two open collaboration areas—and only two private offices. The iconic City Hall concrete ceilings are illuminated with fixtures that cast light up into the latticework, creating a much softer ambient light and overall feel.

The renovation of Room 709 is a permanent addition to City Hall, currently serving the city’s Environmental Department.
