A common reason companies opt for modular workstations is to reduce noise, and the right type of system can do exactly that. It's important to remember, though, that no system will eliminate noise completely - and that some design choices will make your system even less efficient at blocking sound. Lower panels and glass surfaces can make for a more stylish look, but they both reduce noise absorption.
Aesthetics are also important. Leading modular workstation manufacturers provide a range of colors and patterns for fabrics and worksurfaces, allowing you to choose a look that's right for you. Plain can be ok - and can save you some money - but nicer fabrics improve the overall look of your office. On the other hand, if appearances aren't that important to you, you may be able to save money by choosing less popular colors or overstocked fabrics.
In most cases, you'll need electric power and data network connections run through a row of workstations. You'll be able to choose "base feed" - power that comes from a wall outlet - or "top feed", where wires are dropped down from the ceiling. However, electrifying your modular workstations has a big impact on the cost. If your workstations are next to walls or existing overhead power sources, you may be able to save some money by simply adding wall outlets or "utility poles" - non-structural columns that conceal wiring.
Various storage options are available with modular workstations, including filing drawers, wheeled pedestals, wall shelving or cabinets, and free-standing bookshelves, many of which have the option to include locks. Sometimes these are configurable by your employees, allowing each person to set up their workstation the way they see fit.
For computer-intensive tasks, keyboard trays are a welcome addition. Some systems go a step further by allowing the entire worksurface to be raised or lowered.
Other common add-ons include whiteboards, windows, built-in task lighting, coat hangers, and tack boards. Modular workstation vendors can give you more details on what extras are available, and in most cases you'll be able to add them later with little or no extra expense.
