Structural calculations in Helmond

Extending an addition built in several phases

Where can you find local information?

Helmond’s files through 1999 are held by RHCe. Records from 2000 are requested from the municipality. If construction phases fall on both sides of that date, two requests are needed. The municipality supplies available files for the requested address or location.

Extending an addition built in several phases

When enlarging an existing extension, its former external wall may become an internal line. Sketch retained parts and the new roof connection. Gather records for both phases, even if the older addition looks identical. Its foundations and connections need assessment for their new role.

These points help you prepare. They are not an assessment of a particular property.

Educational illustration; not a photograph or calculation for a local project.

Three actions to prepare your enquiry

  1. Check whether both RHCe and municipal records are needed.
  2. Mark the former external wall within the proposal.
  3. Include foundation and roof records for the first extension.

What scope fits your proposal?

Send the records you have found together with your proposed changes. We discuss the calculations, structural drawings and any additional information required. An archive record describes a documented situation; its correspondence with the current building needs assessment. The quotation defines the work and price.

Check permits and other consents separately for the project address. Our structural approval guarantee covers additions to our own documents within the agreed scope. The municipality decides on planning and permit approval.
