Getting a driveway is a great idea, but you need to consider the cost. The cost will depend on several factors. One of them is the size of the driveway. The driveway that is meant for a single car will cost less than a bigger driveway. Thus, you need to consider how large you will make it. Talk to contractors and in most cases, they will charge per project. You have lots of paving options in Dublin. Do consider the quality and the design, as well.
It is up to you to decide whether you want to go for gravel, asphalt, macadam or concrete. These materials will have different qualities of driveways.
