Describe the join on every side
Describe where the addition meets the retained house at the roof, walls, floors and services. Give each junction a reference and attach available current drawings. A line on a floor plan alone may not describe what remains at a roof or external wall. Leave uncertain connections for the responsible professional to assess.
Assign the exposed-edge handover
Ask who takes responsibility for each exposed edge after removal and before the next construction stage. Record the required condition, receiving party and dependencies. Weather protection and closure of openings need an explicit arrangement; they are not guaranteed by naming the removal 'partial demolition'. Keep design and reconstruction responsibilities distinct.
Check the occupied side
Identify the rooms, entrances and services intended to remain in use on the house side. Bring that information into the professional and contractor review. Do not assume that an occupied room is unaffected because it lies outside the marked addition. The occupancy guide provides the separate questions to discuss.
Keep an interface register
For each junction, record the drawing reference, retained element and handover responsibility. Use the addition demolition page to explain the removal request and the engineering guide for design interfaces. This register coordinates questions; it is not a sequence for dismantling an attached structure.
Addition interface register
Copy these headings into your own working document and complete the rows for your property. The prompts are not findings or approval of work.
| Junction | Retained element | Receiving party and condition |
|---|---|---|
| Roof / wall junction | Fill in | Professional drawing and closure responsibility |
| Floor / opening edge | Fill in | Support and next construction scope |
| Service crossing | Fill in | Responsible trade and confirmation |
Keep your completed record private. Bring the relevant scope questions into the optional project planner or discuss them directly with Clearpath.
