    Detailed construction drawings

    This course introduced us to the basics of New Zealand Building Code (NZBC) and Department of Building and Housing (DBH). Drawings are presented below as part of a series of a bigger project detailing selected features of a house (group project). Of particular focus was reference to NZS 3604: Timber Framed Buildings.  

    The most interesting thing about this side of Architecture was learning about the core structure of a built form. Having knowledge in the science of construction gives the designer more opportunity, flexibility and strength to design not just an aesthetically or sensorally pleasing form, but a functional one as well.
