Here is a glossary of features of a floor plan drawing. Scroll down for a visual glossary!
CAD | Computer-aided design; accurate, precise software used to draw up surveys
Dashed Lines | Dashed Lines represent objects above 1-metre cut point on a drawing, e.g. loft hatches, beams
Doors & Windows | Doors and windows are shown using standard templates (please see our visual glossary below). ‘CH’ stands for ‘cill height’ and ‘WH’ for ‘window height’
Drawing Titles | Every drawing has a title, including a scale and scale bar
Elevations | After surveying a building or area, we produce a 2D ‘plans and elevations’ drawing. The view from the sides are called the elevations (the view from the top is called the plan)
FFL | Indicates a finished floor level
Fixed Furniture | Permanent, fixed furniture and features of a room, e.g. toilets, cookers, basins. We do not precisely survey these as standard
Hatching | A shading technique used to show shrubs, hedges and areas of dense vegetation
Numbers With Crosses | Numbers with crosses are spot heights. The cross represents the location of the measurement; the number shows the level of land or surface in relation to another (in metres). Sometimes we survey spot heights to Above Ordnance Datum (AOD), sometimes to arbitrary datum
PDF | Portable Document Format, a file format containing all the elements of a printed document as an electronic image that you can view, navigate, print, or forward to someone else.
Plan | After surveying a building or area, we produce a 2D ‘plans and elevations’ drawing. The view from the top is called the plan (the view from the sides are called the elevations)
RWP | Indicates a rainwater pipe
Section Lines | Section lines represent a cut line through the building for an accompanying drawing. The numbers and letters indicate drawing number and specific section
Stairs | Arrows on stairs and ramps are in the direction of up. Lines through the middle of stairs are break lines, representing a cut-off point as the stair goes above a certain height
SVP | Indicates a soil vent pipe
Thick Lines Thick lines indicate significant structural and internal partition walls
