1.0 Introduction In this project, we are required to design a bungalow and prepare structural drawings for the bungalow. This project involves structural theory, force calculation and basic structural proposal which allows further understanding of structural analysis. I obtained and modified few minor parts to produce a set of architectural drawings of a two or three-storey bungalow, which includes ground floor plan, first floor plan and roof plan that fits the project brief. As stated, only grid lines, dimensions and room names are required.Further on, I also carry out structural framing for the bungalow to include the position of columns, beam to beam and beam to columns connections for each level. Followings are the brief building background.
