Retained-building planning
Interior demolition when a house becomes separate dwellings
- Interior scope
- Renovation planning
A reviewed conversion changes more than the number of kitchens. Separate circulation, retained rooms, service routes and new separations can interact across several floors. Map the whole proposed arrangement before deciding which interiors should leave.
CoreCut assesses interior demolition and separately designed openings. The designer and relevant authorities determine whether the conversion is permitted and what the building requires. This guide grants no unit-count entitlement or tenancy advice.
Compare current rooms with the proposed dwellings
Mark the existing stairs, halls, kitchens, bathrooms and entrances. Overlay the new arrangement and distinguish retained rooms from new construction. A former doorway may close while another route changes; those are separate tasks with different receiving trades.
| Illustrative area | Removal decision | Following responsibility |
|---|---|---|
| Retained upper rooms | Selected finishes only, if required | New services or finishes specified by the design |
| Lower kitchen/bathroom area | Defined fixtures, layers and obsolete partitions | New installation and any designed concrete interfaces |
| Shared former circulation | Specific interior changes | New separation, doors and compliant circulation design |

The table is a layout comparison, not a compliant dwelling plan. The professionals resolve fire, acoustic, access and service requirements for the actual building.
Distinguish removal depth from the conversion outcome
The selective-removal versus full-gut guide helps compare how much existing interior to expose. A new dwelling arrangement does not automatically require every finish removed, nor does a selective package guarantee that concealed conditions will suit the new construction.
Identify known material, service and structural questions before affected work. Record how the project team will resolve discoveries instead of treating every newly visible item as included removal.
Keep openings tied to the design
If a foundation opening is specified, the egress-opening guide addresses that component. The wider conversion still needs its room and circulation plan; an opening alone does not approve a dwelling.
An illustrative project might retain upper bedrooms while reconfiguring lower rooms and constructing a new separation. Another could change kitchens on more than one level. The removal scope follows those actual boundaries, not the number of proposed units.
Bring all floors to the assessment
Discuss the demolition portion with CoreCut with the current/proposed layouts, design contact, retained rooms and specified openings. Identify who handles new separations, services and reinstatement. Start from the reviewed project rather than asking a removal contractor to determine conversion feasibility.
For a proposal that also changes a garage, the garage-conversion removal guide distinguishes stored contents, retained structure and the designed slab or opening changes.
