Pick your space
When choosing a work area, it's a good idea to keep it away from your living room. Having a separate space makes it easier to focus when you're working and easier to switch off when you're not working.
Remember to make sure you have access to power; you might need to use extension leads and power boards.
To save time shifting office furniture around, it's a good idea to draw it up first.
If you work on a computer, having a couple of light sources cuts down on screen glare. Areas with natural light are good, but you can always use desk lamps if necessary.
Corners are great for office setups as they take up less room and choosing an L or U desk shape keeps everything in easy reach.
If you're short on space, the stand up desk is another option.
Personalise your space
Having a home office means you can decorate it any way you want. Pictures are a good idea and plants bring life into your space. Pin boards are also good for organisation and visual management.
You might also want to think about a fresh coat of paint. A splash of colour may have the power to change how you work; for example blue is peaceful, green is calming, red is passionate and yellow is optimistic.
