One of the biggest downsides of working from home is that there are always other things you can be getting on with, or distractions which can take you away from your work. Whether those distractions are having pets in the house needing your attention, the cleaning you think you should be getting on with, or simply the TV!
One way to get over these distractions is to install a home office within your garden. This way, you have a separate space in which to work which can be totally free of distractions. Depending on how you build your office, you can be as isolated as you can be, with no TV, no pets, no housework to think about. Because you are having to physically walk out of the house to get to your office space, it will feel more like you are going to work rather than working in your home.
