The terms 'soft strip demolition' and 'full demolition' are sometimes used interchangeably — but they describe very different types of work with different scopes, costs, and outcomes. Understanding the distinction helps you specify the right service and ensures you're comparing like-for-like when getting quotes.

What Is Soft Strip Demolition?

Soft strip demolition (or soft strip out) is the selective removal of all non-structural internal elements from a building. The structural frame — walls, columns, floor slabs, roof structure — is retained throughout. Everything else is systematically stripped out: suspended ceilings, partitions, floor finishes, M&E services, ductwork, pipework, fixtures, fittings, and joinery.

Soft strip is typically carried out for one of two reasons: as an enabling phase before full structural demolition (to reduce hazardous material risk and maximise material recovery), or as a standalone service ahead of building refurbishment (to return the structure to shell and core condition).

What Is Full Demolition?

Full demolition is the complete removal of a structure — structural frame, foundations, and all — typically down to ground level or below. It is carried out when a building is beyond economic repair, when the site is needed for redevelopment, or when the structure is unsafe. Full demolition typically follows soft strip: removing the internal fit-out first reduces hazardous material risk during structural works and allows better segregation of demolition arisings.

When Is Each Used?

Soft strip only — when a building is being refurbished and the structure is being retained; when a lease is being surrendered and the tenant is required to remove fit-out; when a building is being converted to a different use.

Full demolition only — rare; usually occurs where the structure has no fit-out to remove (e.g. a bare agricultural building) or where the structure is structurally unsafe for safe soft strip operations.

Soft strip followed by full demolition — the most common sequence for redevelopment projects. The soft strip phase removes hazardous materials in controlled conditions and maximises material recovery; the full demolition phase then proceeds safely.

Cost Comparison

Soft strip out is typically priced by floor area (£12–£35/m² depending on M&E complexity). Full structural demolition is typically priced by volume or building type, with the cost partially offset by the scrap value of steel and the reuse potential of concrete aggregate. A combined soft strip and full demolition programme is quoted as a single scope by JWD, ensuring cost efficiency and programme coherence.

Jim Wise Demolition's Approach

JWD delivers both soft strip out and full structural demolition with the same team, under the same management, on the same project. This eliminates the programme risk and cost uncertainty that comes from appointing separate contractors for each phase. Read our comprehensive guide to soft strip out for more detail on the process.
