What are the principal advantages of creating a conceptual design model using masses before diving into the detailed design and building element modeling?
The principal advantage is saving time. The conceptual design will give a good idea of the space and shape of the structure, and how it looks within a certain city scene. For several different design ideas, Forma can just show a very preliminary sketch that takes a shorter amount of time to create than drawing them from scratch. Additionally, during the conceptual modeling, the client does not need to see so many details, as that will be designed after the final structure footprint is decided.
It is also easier to display the conceptual model in a simpler software like Forma, where changing floor plans and structure heights can be done with a quick drag and drop function. This could be helpful during synchronous client meetings, where more ideas may be presented on the fly. The model can easily be changed to see how that vision will fit.
Should all buildings be modeled first using conceptual masses?
Not all buildings will need a conceptual mass model. Typically, larger structures that take on more complicated, non-traditional forms will need the concept model. These types of structures typically need to be modelled within its designated site to see how they will fit in the skyline. It is also helpful for understanding the scale of the structure. Overall, the conceptual masses are used as a way to communicate the design. Simpler structures such as a small house may not need to be modelled, as they are typically a standard shape and size. Because they are smaller, it can easily be designed in Revit in more detail due to its scale.
