We try to minimise as much as possible the time to completion. We should be able to give you an estimate for this if you ask us once we discuss the project. The thing that slows us the most is that some projects simply don’t allow for multiple people to work at once.
For example, an extension project or extensive internal alterations allow us to use most of our team members. This means that, despite the fact that it takes a lot of work to finish the project, the work is divided amongst multiple persons. For smaller projects, it’s hard to work with more than 2-3 people at once; this happens because you can’t divide the task effectively among the team members or sometimes there’s simply not enough space to work for all of them.
