Selective demolition in Denmark and the 250 square metre threshold

• Selective demolition uses the floor area actually removed when assessing the threshold.
• Covered projects need an authorised demolition company.
• Client-side coordination and the demolition company’s responsibilities are different roles.
• Earlier permit applications can affect whether the new provisions apply.

Start a selective demolition review by describing the work precisely. Identify whether the project removes an entire building or a defined part, and record the floor area involved. The general size of the site is not enough. Keep the relevant drawings and area basis with the assessment so later changes can be checked against the original decision.

Ask for advice where the scope or area calculation is uncertain. Selective demolition has consequences for procurement, planning and execution, so a vague description such as “partial strip-out” may not answer the applicability question. Do not presume that every internal alteration meets the same condition as complete removal of covered floor area.

The Danish Environmental Protection Agency explains the transition for demolition begun before 1 July 2025 and cases with an earlier demolition-permit application. Review the project’s documents and the current guidance before deciding which provisions apply. A selective demolition assessment should identify the date being relied on and why it is relevant.

Keep the conclusion connected to the assessed scope. If the project changes substantially, ask the competent adviser and municipality whether the earlier conclusion still holds. Selective demolition should not be treated as a label that is fixed forever by the first tender document. Record any later clarification alongside the original basis.

For covered selective demolition, verify the demolition company’s authorisation before appointment and again if the performing company changes. The authorisation arrangements include a quality management system and a resource-responsible person. These company functions do not remove the client’s separate need to appoint the required environmental and resource coordinator.

Make responsibilities visible in the appointment. Ask who controls material separation, supervises the company’s work and provides agreed records. The selective demolition programme should allow those responsibilities to be carried out. A tender that requests only a price and completion date can leave important planning and documentation questions unresolved until the work is already under way.

Selective demolition aims to separate materials during dismantling and address problematic substances appropriately. Use the project’s assessment and plan to organise the work sequence and material destinations. Obtain task-specific specialist advice where environmental or structural conditions affect the sequence. This guide does not provide a demolition method for an individual building.

Agree practical arrangements for identified materials. The team needs to know where fractions will be kept, how they will be identified and who checks changed conditions. Selective demolition can lose its intended value when material is mixed because space, labels or collection arrangements were not agreed. Resolve those operational questions before the relevant activity begins.

The miljø- og ressourcekoordinator, or MRK, supports the client in covered selective demolition. The coordinator helps ensure the standardised demolition plan is prepared and submitted and follows its implementation. Read the dedicated MRK guide for the appointment, access to information and practical coordination responsibilities.

Avoid assuming the MRK and the demolition company’s resource-responsible person are automatically the same appointment. Selective demolition involves distinct functions even when a qualified person can perform more than one role. Record who carries out each function and how instructions, observations and plan changes reach the relevant parties.

An issued plan needs a clear version and an owner for updates. For selective demolition, record the reason for changes and the information supporting them. If the team discovers a different material or an unanticipated condition, escalate it through the agreed project procedure rather than quietly changing the handling arrangement.

A short coordination review can identify open decisions before they affect site activities. Check the next phase, the material information available and any outstanding clarification. Selective demolition documentation should help the team decide what can proceed and what needs further assessment. A long report with no clear actions is difficult to use when the site sequence changes.

Discuss the area assessment, permit information, environmental findings, approved company details, plan versions and material records with the responsible specialists. The records needed for selective demolition depend on the applicable provisions and project conditions. These examples are a procurement discussion list, not a replacement for the statutory plan or competent advice.

Where photographs support material records, identify the location, date and activity. Retain destination or transfer information where it is relevant to the agreed delivery. Review consistency between documents. Selective demolition is harder to follow if the plan names one material stream while the issued records use a different, unexplained description.

The relevant regime was introduced from 1 July 2025. Source information was checked on 9 October 2026. Before starting selective demolition, recheck current provisions, the project’s transitional position and the actual authorisation status of the appointed company. Keep publication dates and project application dates separate.
