This project is a Topographical Survey and Site Plan of an existing site in Maida Vale Road in Wellington. The purpose of this survey was to assist the architect with the redesign of the existing dwelling. All relevant site features have been plotted including heights on neighbouring buildings so that the impact of house alterations on sunlight and views can be analysed. The Site Plan produced is fully electronic and can be directly imported into the architect’s computer CAD system. We find that we are often asked to carry out such surveys on difficult steep sites where a detailed Site Plan is essential for building design and determination of compliance with Council’s District Plan rules.
