Creating a design that is visualised and sketched by a designer is of course a significant architectural challenge but is taking that design on for design development and detailing more challenging? Is taking that visualisation into 3D and 2D and construction drawing sets likely to maintain the design intent and is it efficient to allow someone else to develop a design. Also, why does it become a challenge and what type of issues and problems arise as a result and how do we overcome the challenge – i.e. involving the designer/architect at various stages and sign off points. Raising design inconsistencies with the architect for clarification etc.
