Exterior Glass Block Walls can be a dramatic addition to a building, but may not work everywhere. Sun and views need to be handled with care. This example is an industrial building where bringing light in through a stairway seemed desirable. Views were ’industrial’ and not a concern.
This glass block wall emphasized the entrance by its size and curvilinear plan. There is a limit to the size of glass block panels. This made it necessary to have intermediate curvilinear beams to carry the block as well as column-backed mullions.
Another feature of glass block that needs care is how it is terminated, which you see below in the details. These requirements are spelled out in the manufacturer’s installation guidelines (see Comments).
Glass block is about the same cost as low rise curtain wall. The ability to curve the wall without segmentation is unique in light transmitting wall materials.
 

Exterior Masonry Door Details in Cavity Walls require attention to closing off the cavity and controlling any water that may have entered the wall above the door. 
The key features of the detail are the:

• a cavity vent that prevents mortar droppings from clogging the bottom of the cavity
• masonry flashing to direct any moisture to the exterior
• weep vent to let moisture out of the cavity and to equalize air pressure in the cavity with the outdoors (a similar vent is often placed at the top of the cavity)
• identifying the method for closing off the cavity above the door.
• reference to the structural lintel needed.

For the past 10 years all new commercial buildings have been required to have every toilet room comply with accessibility. ADA and ANSI publish the criteria for accessibility. For the profoundly handicapped person these standards do not go far enough. These toilet rooms below show what is needed in those cases.
The single occupancy toilet rooms shown here are the usual solutions that you see everywhere, except that they have a little more space because someone often is needed to assist the individual.
The larger toilet rooms require much more space than regulations dictate because some of the adults that use these rooms need assistance from one or two people, a lift and a changing table. You will note the cubicles separated by curtains, the toilet placement with double grab bars and space for a 3' x 7' hydraulic table. We learned the hard way that a facility for the handicapped needs more than code compliance.  

Guard Rails and Handrails are needed in several locations in buildings - stairs, ramps. mezzanines, floor openings, etc. The building code and ADA accessibility regulations have an impact on placement, heights, and configuration. 

In most occupancies any openings in a guard rail must be small enough to prevent the passage of a 4" sphere. Vertical pickets are the simplest and least expensive way to accomplish this. Other methods are a low wall, grids, panels of expanded metal lath and glass panels.

Hand rails are limited in profile and circumference. A painted metal tube/pipe is cheapest but has the drawback of being easily scratched or worn by hand contact. Wood doesn't show this wear as easily, nor does an aluminum or stainless steel tube. Often these round shapes are fastened to a U-shaped channel by a fastener on the underside. Here wood is shaped to fit a flat surface for attachment.  See the Comment paragraph for download link.

Simple Counters, those without other casework, are useful in various situations: reception areas where loose drawer units can be used, mail room, copier alcove, even work stations. By detailing the conditions, you create a basis for the level of detail that the project should receive. 

These details are suggested to specify any special configuration, construction and materials required for the conditions you need, especially heights and spans. The wall shown forming the freestanding counter is not self-supporting. Add return walls or fit it between two columns.

Details like these could act as typical details covering many different counters.
