What to include in an existing-home measurement brief

Give every room a stable identifier

Use a simple room name and floor designation that will stay consistent across sketches, photographs and notes. If two spaces are both called bedroom, add a distinguishing label. Include a rough sketch showing their relationships and the route between them. A reviewer should be able to connect a photo of a doorway with the corresponding opening on the sketch without relying on the memory of whoever visited the property.

Define what each measurement means

Record whether a dimension is taken between finished wall faces, another visible surface or an inferred boundary. Note ceiling heights separately from room widths and depths. For irregular rooms, capture the additional offsets needed to explain the shape rather than forcing it into a single rectangle. If a measurement is difficult to access, mark it as approximate. Do not silently substitute a convenient value for a missing observation.

Document visible constraints

Photograph columns, changes in level, windows, doorways and visible services that affect the proposed use. Explain where the photo was taken and which direction it faces. Avoid conclusions about structural roles or concealed utilities from appearance alone. An existing wall may require investigation before it can be altered. Identify those questions in the brief so a qualified professional can decide what surveys, records or further checks are appropriate.

State the purpose of the study

A room-layout exercise needs different information from a structural alteration or a detailed cost estimate. Explain the intended decision, the required output and who will review it. In TranslateDesign, a manual rectangular room model can organize a concept, but it is not a surveyed record of the building. Keep the original observations and uncertainty notes alongside it so simplified geometry is not mistaken for complete evidence.

• Use consistent room and floor labels.
• Record units and measurement endpoints.
• Label approximate or inaccessible dimensions.
• Keep photos, sketches and proposed changes distinguishable.
