YOUR STRUCTURAL ALTERATIONS ENQUIRY
Plan your structural alterations work
Plan a structural alteration with drawings and the intended layout change. Ask about assessment, design, temporary support, approvals and making good before any removal.
What to include in your enquiry
- The alteration and intended use of the space
- Structural drawings or assessment already available
- Occupancy, services to coordinate and finish to make good
- State whether you own, rent or manage the property and who can authorise this structural alterations work
What should the quote cover?
Compare structural design assumptions, temporary support, installation, inspections and making good. Specify what is provisional until opening-up and how changes are approved; decorative reinstatement and structural completion are different deliverables.
Can a builder price wall removal without knowing what the wall supports?
A meaningful scope needs that question addressed. Ask which assessment and design information are required before committing to the alteration.
Property and responsibility checks
An alteration needs assessed structure and a design, not a wall guess. Confirm address-specific permissions and retained fabric before opening up, with temporary support and service routes included.
- Identify the actual property, asset and owner before commissioning changes
- Include relevant plans, reports or permission information; do not assume approval
- Agree access, protection and making good where the work affects retained surfaces

Do not remove first and assess afterward
Quick answer
Plan a structural alteration with drawings and the intended layout change. Ask about assessment, design, temporary support, approvals and making good before any removal.
Enquire about a wall opening or other structural alteration, with the design, assessment and construction responsibilities established before work is agreed.
A proposed opening or wall removal needs an assessment of the structure and affected building before work starts. Appearance does not establish whether a wall is load bearing or what it supports. Do not remove material, install improvised props or rely on an online beam-size guide. HSE requires alteration work to be planned and carried out competently to prevent unplanned collapse. An unsafe existing structure needs direct appropriate help; this form does not provide emergency assessment.
Design the complete load path
The design must consider the retained structure, supports and how loads are carried, not only the visible beam. Ask who undertakes assessment and calculations, how findings are communicated and which drawings govern construction. Temporary works and the permanent structure need their appropriate design and responsibility. Existing services and concealed construction can affect the proposal. A supply price for a steel member is not a complete alteration plan. The actual building requires suitable professional input.
| Part of the proposal | Clarify |
|---|---|
| Permanent design | Who assesses the retained structure and specifies the final arrangement? |
| Temporary conditions | Who designs and manages support and the work sequence? |
| Construction and records | Who follows the agreed details and obtains required inspection evidence? |
Temporary support and work sequence
HSE explains that temporary support must be designed, installed and maintained for foreseeable loads. Ask who plans the sequence, manages support and confirms when each stage may proceed. Do not assume the builder’s permanent beam calculation covers every temporary condition. Keep occupied areas separated through the contractor’s safe arrangements. If assessment changes the design, pause dependent work until the appropriate revision is agreed. This site does not specify props or authorise a demolition method.
Keep design, approval and adjoining rights separate
Describe the opening or layout change you want, with any existing drawings and reports. The proposal needs appropriate structural design and assessment; do not infer a wall's role from appearance or remove material to test it. Agree who provides design, building-control information, temporary support and completion records.
Services and the finished room
The opening can affect wiring, plumbing, heating, finishes and doors. Define the qualified trades and order of work. Fire-related design requirements and interfaces need assessment for the whole proposal, not an assumption that covering a beam completes compliance. Agree floor/wall/ceiling reinstatement and decoration separately where needed. The room outcome should be described alongside the structural scope, with access and temporary loss of services understood before comparing construction quotes.

Tell us the intended change
Provide postcode, intended opening/change, current drawings and known property restrictions. Photos can explain the brief but cannot prove structural safety or substitute for a site assessment. We review requests and may help connect suitable local building businesses. Sending an enquiry does not book an engineer or builder, approve work or guarantee feasibility. Use direct appropriate help if there is an existing immediate safety concern.
