Frequently Asked Questions

  • If the wall is load bearing, a structural engineer is usually required to assess the loads being supported and design any necessary steel beams or other structural supports. Structural calculations are typically required for Building Control approval before work can proceed.

  • A load bearing wall supports the weight of floors, roofs, or other parts of a building above it. Removing or altering a load bearing wall without proper structural design can compromise the stability of the property. A structural engineer can determine whether a wall is load bearing and advise on the safest solution.

  • Most extensions require structural calculations to demonstrate that foundations, walls, beams, and other structural elements are adequate for the proposed loads. These calculations are generally required by Building Control as part of the approval process.

  • Yes. Most loft conversions require structural calculations for new floor joists, steel beams, roof alterations, and load transfers. These calculations help ensure the conversion complies with Building Regulations and is structurally safe.

  • The cost depends on the size and complexity of the project. Simple structural alterations may require only a site visit and calculations, while larger extensions or loft conversions typically involve more detailed design work. We can provide a quotation based on the specific requirements of your project.

  • The timescale varies depending on the complexity of the project and the information available. For straightforward residential projects, calculations are often completed within a few working days, while larger or more complex schemes may take longer.

  • Most structural alterations, including removing load bearing walls, installing steel beams, loft conversions, and extensions, require Building Control approval. This ensures the work complies with current Building Regulations and safety standards.

  • Yes. A structural engineer can assess cracks and determine whether they are cosmetic or indicate a more significant structural issue. They can advise on the cause of the cracking and recommend any necessary remedial works.

Party Wall FAQ’s

  • A party wall agreement is a legal document prepared under the Party Wall etc. Act 1996 when certain building works affect a shared wall, boundary, or neighbouring property. It sets out how the works will be carried out and helps protect the interests of both owners.

  • A party wall notice is usually required before carrying out certain works near or on a shared boundary, including extensions, loft conversions involving party walls, and excavation close to neighbouring properties. The notice must generally be served before work begins.

  • A neighbour cannot normally prevent a lawful extension simply because they object to it. However, if the works fall under the Party Wall etc. Act 1996, the correct procedures must be followed before construction starts.

  • The process can vary depending on whether neighbours consent to the works. Where a formal party wall award is required, the process often takes several weeks, so it is advisable to begin discussions early in the planning stage.

  • In most cases, the building owner carrying out the works is responsible for the reasonable costs associated with the party wall process, including surveyor fees where applicable.

  • If a neighbour does not respond within the statutory period, they are generally considered to have dissented. Surveyors are then appointed to resolve the matter and prepare a party wall award.

  • Many rear extensions require a party wall agreement, particularly where excavation is taking place close to neighbouring foundations or where works affect a shared wall. A party wall surveyor can advise on the specific requirements of your project.

  • Starting work without complying with the Party Wall etc. Act 1996 can lead to delays, disputes, and potential legal action. It is advisable to establish whether the Act applies before construction begins.

  • A party wall surveyor administers the requirements of the Party Wall etc. Act 1996. They prepare notices, assess the proposed works, record the condition of neighbouring properties where required, and produce party wall awards.

  • Costs vary depending on the complexity of the project and whether one or more surveyors are involved. Fees are typically influenced by the extent of the works and the level of agreement between neighbours.

  • It is advisable to contact a party wall surveyor as early as possible in the design process. Early advice can help identify whether the Act applies and avoid delays once construction is ready to begin.
