Full versus selective scope
| Criterion | Full demolition | Selective demolition / strip-out |
|---|---|---|
| Objective | Clear a defined structure or major portion | Remove defined components while retaining other structure or finishes |
| Protection | Site and adjoining-property controls | Protection of retained areas and interfaces is central |
| Cost structure | Machinery, access, debris, utilities and clearance | Controlled labour, sequencing, protection, interfaces and targeted waste |
| Hazards | Assessment and specialist remediation remain separate | Assessment and specialist remediation remain separate |
| Closeout | Clearance, foundations/slabs where scoped, grading | Condition and readiness of retained areas for renovation |
US and UK terms are related, not identical
The US calculator uses interior demolition, garage/outbuilding, and whole structure. The UK calculator uses internal strip-out, garage/outbuilding, and house/structural demolition. A strip-out is not automatically equivalent to every selective-demolition scope; define the retained elements and project objective.
Why selective work is not automatically cheaper
Less debris can reduce some disposal, but retained walls, services, finishes, access routes, dust controls, sequencing, investigations, and repair of interfaces can increase labour and protection. Compare itemised proposals rather than assuming scope labels determine price.
Hazards and utilities remain specialist issues
Neither option authorizes structural dismantling, hazardous-material removal, or utility disconnection. Surveys, controls, licensed work, permits, and site-specific assessment remain necessary where applicable.
Choose the calculator scope that matches the outcome
Use the live scope selector as a planning baseline, then verify retained work, protection, utilities, waste, and closeout in the written project scope.
Plan with the right calculator
Enter your project details and select the United States or United Kingdom market for Low, Typical, and High planning estimates.
Frequently asked questions
Does demolition include asbestos or lead removal?+
No. The calculator allows for a survey or assessment, but hazardous-material identification and remediation are separate specialist scopes.
Is selective demolition always cheaper?+
No. Retaining structures and finishes can require protection, sequencing, investigations, and controlled labour that change the cost structure.
Are utilities included?+
Only as a selected allowance. Utility identification, disconnection, isolation, and reconnection must be arranged through appropriately qualified parties and relevant providers.
Is rebuilding included?+
No. Demolition and site clearance are separate from renovation or reconstruction.
