Having a designer that is hands-on can make a huge difference in the value from the multi disciplines involved in the design process. Employing the individual that designs the project, through to completion has many benefits. Firstly the importance of in-house approach, one person takes responsibility for the completed project from inception, rather than multi-trades stepping on each-others toes with nobody taking control. The benefits of the craftsman / designer goes back centuries resulting in projects exuding the passion and the expertise of the artisan. The multi-disciplinarian is far more likely to be current with the latest technology, materiality and construction techniques and is far more likely to be able to push the envelope in terms of what is conceivable, to add understated visual references.
