When launching a Work from home enterprise it is foolish to compromise on space, you will need plenty of it and it should also be separate from the rest of your family. It is completely unworkable to try to work from home by sharing space with other householders. If you will be carrying out mainly Online jobs or computer based tasks you may not need too much space at all, just space for a desk and some storage.
One great way of getting such space is to convert your garage. It’s surprising the amount of space this can create for you. A standard and fairly modern single car garage will measure nine feet by eighteen and a double garage is usually in the region of eighteen feet square. So even the smaller one could offer adequate work from home space as it will be at least as spacious as a normal home office.
However you will need to consider the conversion to habitable use. A garage is normally designed simply to provide security for your car, so it will probably be poorly insulated. The most difficult garages to convert are detached prefabricated structures. With these it will be essential to install an insulated floating floor and it will also be necessary to add insulation to both the walls and the roof. The cost of all this will not be insignificant so you should carry out a proper costing before proceeding. Also, fixing all this additional structure will shrink the amount of space available inside, so you need to think about this when assessing the space available. Finally power and heating will need to be available to the converted garage.
A lot easier to convert will be the integral garage which is a common feature of modern houses. These normally have better insulation and will probably be fitted with power as well. Integral garages can be the most satisfactory solution to the work from home space problem.
