Project management may seem like an additional expense, but 95% of people overspend on their build by at least 20% - 30%. Project management will ensure tighter control of your budget and that it is used in the most efficient way and greatly reducing your risk of overspending.
Fees are based on each individual project, subject to the complexity and size of the build and how much project management you require.
My full project management fee is in the region of 6.5% - 9% percentof the project buildcost. Fees are fixed with no hidden costs or extras. Payments are spread evenly throughout the project.
