House of Lords to review subterranean developments

Published: 05/01/2012

Concern at the rapid growth of unregulated extensions of property below ground (subterranean/basement developments) has led to the introduction in the House of Lords of a private members Bill, the ‘Subterranean Development Bill’.

The Bill, introduced by Lord Selsdon, is in response to demands of residents and other property owners for better protection from adjacent, or nearby, redevelopment involving underground and related construction work. The Bill includes the following clauses:

  1. Subterranean development works (definition)
  2. Application
  3. Approval
  4. Notice to adjoining owners and disputes
  5. Suspension of works and access
  6. Security for expenses
  7. Liability
  8. Code of Practice for subterranean development works
  9. Building owner responsibilities
  10. Council Tax valuation
  11. Application of Party Wall etc Act 1996
  12. Definitions
  13. Commencement and short title

Schedule 1 - Code of practice
Schedule 2 – Building owner responsibilities

The Subterranean Development Bill can be found on the UK Parliament website.
