Useful context for St George
For a house or extension, show the relationship with party walls, neighbouring roofs, garden levels and retaining features. A rear addition on a level street differs from an outbuilding on a falling plot. Mark what holds back ground and what remains after removal. State known service and drainage routes, and obtain structural advice where the work could affect a shared or retaining wall. The proposal should explain temporary and final stability, not simply list the volume to be demolished.
Former-site questions should be handled carefully. Where records show an industrial use or made ground, ask environmental and design professionals what investigation is proportionate to the planned work and end use. Do not extrapolate Troopers Hill's documented history across all of St George. Likewise, a roof or lining that looks old should be described and surveyed where appropriate, not diagnosed by a homeowner or from a photograph. Give bidders confirmed information and keep uncertainty visible.
