Home alterations and residential structural engineering

Most homeowners meet a structural engineer for the first time when they want to change something about their house — open up a kitchen, add a rear extension, convert a loft or take out a chimney breast. The engineering behind those changes is usually straightforward, but it has to be right: the load has to have somewhere to go, the supports have to be adequate, and the information has to satisfy Building Control and be clear enough for a builder to price and construct.

Bebbington Engineering Studio provides structural advice and design for houses, extensions, loft conversions, internal alterations, removal of load-bearing walls and change-of-use projects. Work is carried out personally by Carl Bebbington, a Chartered Structural Engineer, so the person who looks at your drawings is the person who answers your questions later.

Typical projects

  • Single and double-storey rear or side extensions
  • Removal of load-bearing walls to form open-plan living space
  • Loft conversions, including new floor structure, dormers and roof alterations
  • Chimney breast removal and associated support
  • New openings in existing masonry walls
  • Garage and outbuilding conversions, and other changes of use
  • Underpinning enquiries and localised repair or strengthening

Who it is for

  • Homeowners planning an extension, conversion or internal alteration
  • Self-builders and people project-managing their own works
  • Architects and architectural technologists needing structural input on residential schemes
  • Small builders and contractors who need calculations to price and build from

What we typically need from you

  • A short description of what you want to achieve and where the property is
  • Existing and proposed drawings, where these have already been prepared
  • Photographs of the areas affected, inside and out
  • Any survey information, previous reports or Building Control correspondence you already hold
  • Details of anything already known about the structure — historic movement, previous alterations, unusual construction

What you typically receive

  • Structural calculations for the altered or new elements
  • Sketches or structural drawings suitable for Building Regulations submission, pricing and construction
  • Beam, lintel, padstone and connection sizes with clear support requirements
  • Foundation advice appropriate to the works and the ground conditions identified
  • Responses to Building Control queries within the agreed scope

Scope and limitations

  • Design is based on the information supplied and what can reasonably be seen without opening up. Concealed structure may need to be verified on site.
  • Ground investigation, drainage design, party wall awards, architectural design and planning applications are separate services and are not included unless expressly agreed.
  • A structural design for specific alterations is not a condition survey of the whole property.
  • Scope, deliverables and fee are set out in a written appointment before work begins.

If you already have drawings, sending them with your enquiry is the quickest route to a clear scope and fee. If you do not, a description of the works and a few photographs are usually enough to start the conversation.
