There are many benefits of using one company for the whole of your project from design through to construction.
One that has been highlighted to me on numerous occasions lately, is the benefit to the client of having one company taking responsibility for the whole project.
Too often I hear of situations where designers and builders are blaming each other for issues arising on site, which often lead to long delays and additional costs to the client.
When one company is responsible for the project from start to finish, this blame game is avoided and if there are any problems both the designers and builders work together to find the best solution.
