I think it could be a dodgy idea myself. I lived in a house where one of the rooms was only separated from the garage by a breeze-block wall. Whenever the car was backed into the garage, the house stank of car fumes (carbon monoxide?) for hours.
I know that you are saying you never put the car in there yourself, but for me it would add no value to a house with an office that was shared with a garage that was in use. Also, don't forget your heating - I think you're going to need quite a significant power supply going into that garage.
I also think there might be tax implications - not necessarily that the 'office' adds value to your house, rather I seem to remember that if tax officials are so inclined, they can decide that if a business is being run from a domestic property, then a proportion of the increased value of a property can be taxed as a business profit. Having an office listed in the description of a house that's been sold might be sufficient to trigger that thought in the tax inspector's mind. Although just claiming a proportion of e.g. domestic energy bills might be enough to start that process. With property prices in the UK being so over-inflated, it might well be worth looking into this issue. Furthermore, you could end up having to pay business rates on the office.
