A building drawing records a building or proposal graphically, for example through a plan, section or elevation. Its purpose and revision determine how it can be used: an initial sketch is not automatically a document suitable for construction.
How this term relates to your project
For an existing Haarlem home, archive drawings can help explain earlier alterations and original layouts. Compare them with the actual property rather than treating them as a guaranteed record of what remains. Work may have been built differently or changed afterwards. For a new proposal, identify which drawing forms the basis of each quote, assessment or order.
Include its date and revision so everyone works from the same information. Dimensions, materials and junction details may be developed at different stages. Keep superseded versions separately and record why an update was issued. This makes discussion of a moved opening or revised floor level traceable to a shared document rather than conflicting sketches.
