3D & BIM

We understand two dimensional plans do not always fully convey a design.  That is why the practice utilises the latest three dimensional Building Information Modelling (BIM) software to facilitate virtual walk throughs and 3D images from the very beginning of a project.

The model is developed throughout the design process to ensure the design proposal is communicated as effectively as possible.  It can also be used to estimate running costs energy requirements.
