If you run a web design company or are a self employed web designer / programmer then you may have a place in which you invite clients to come and meet with you. This many be an office that you rent or it may even be part of your home that you have converted into office space. You need your workspace to reflect who you are and what is important to you. It may be that you like to be adventurous with your designs and use bold and bright colours in your workspace. It is always important to have a clean and tidy desk, especially when clients are coming to meet with you. This will give the impression you are organised. If you have to spend ages hunting around for a piece of paper, this does not give a great impression.
When looking at your office space, try and have a designated area that can be used for meetings that is free from clutter and has some visual items around for your guests to look at. Having screens showing your latest work or designs on the wall or logos you have created etc, can be a great way to show off some of your work.
